Title: Improvements in colour photographic materials
IPC: G03C7/388
Filed: 1940-07-23
Abstract: 544,135. Photographic materials. KODAK, Ltd., and KNOTT, E. B. July 23, 1940, No. 12064. [Class 98 (ii)] Photographic material has one or more layers on one or more supports, at least one layer of which is a light-sensitive layer having a colloid binder containing a salt of a salt-forming water-insoluble colloid and a dye-forming substance, e.g. a colour coupler or leuco dye, which does not form a salt with the water-insoluble colloid. The light-sensitive layer may be silver halide gelatine or collodion emulsion layer. The salts may be water-soluble salts such as those of alkali metals, ammonium, ethanolamine, or other strong organic bases, or waterinsoluble salts such as those of alkaline earth or other metals, e.g. magnesium, calcium, strontium, barium, aluminium, cadmium, manganese, zinc, cerium, nickel, cobalt, and thorium, or of organic bases of complex structure or high molecular weight such as quinine or cinchonine. The salts may be soluble in organic solvents. The saltforming colloid may be a natural resin, e.g. whole, hard, soft, or hydrolyzed lac; colophony; dammar; mastic; and sandarach; or a synthetic resin such as polyhydric alcohol-polybasic acid' resins; or cellulose esters of polybasic acids having free carboxylic groups, e.g. cellulose acetatephthalate or cellulose phthalate. The material may have two or more emulsion layers on a single support, preferably all on one side. Colour photographic material of the types referred to in Specification 503,752 may be used. In examples (1), an alcoholic solution of p-nitrophenylacetonitrile and the sodium salt of colophony is added to a silver halide emulsion; (2), as in (1), using the sodium salt of soft lac; (3), cadmium nitrate is added to the emulsion, followed by the addition of an alcoholic solution of 1-phenyl-3-methyl-5-pyrazolone and the sodium salt of colophony; and (4), as in (3), using nickel chloride instead of cadmium nitrate. Specifications 399,713, 410,286, 458,664, 458,665, 478,942, 478,983, 478,989, 478,990, 493,952, 496,196, 496,245, 503,863, 511,180, 519,695, 524,040, 524,154, 524,554, 524,555, 525,874, 525,875, 527,493, 531,246, 531,312, 536,673, 536,939, 537,696, 537,921, 538,914, 540,525, 541,558, 541,589, and 544,134 also are referred to.

Filed: 1939-04-24
Abstract: 528,626. Automatic control systems. EFRAIMOVITCH, Y. April 24, 1939, No. 12230. [Class 38 (iv)] Arcs.-A reversible motor adjusting the electrodes of an arc furnace is controlled as to direction and speed in accordance with the sense and extent of deviation of the arc from a normal condition by a rotatable element such as V of conducting material cut by three magnetic fields, two being energized by coils A, B carrying currents in phase with each other and derived respectively from arc current and arc voltage, and the third energized by a coil C so that its field is 90‹ phase displaced from the others. In normal conditions the torques due to A and B balance, but motion occurs in accordance with the sense and extent of a charge. In a modified form the regulator has two drums on a spindle each surrounded by a four-pole ring, the coil C being found on two poles of each ring and the coils A, B on the remaining poles of each ring respectively. The regulator may drive a mercury reversing switch 1 for the electrode motor. A rheostat XV in the rotor circuit of an asynchronous motor or the brushes of a commutator motor is or are actuated to vary'speed in accordance with deviation of arc conditions by a servo-motor M, controlled by a reversing switch 56 operated by the planet spindle of a differential gear between the elements V, M 1 . Hydraulic adjusting means may be used.

Title: Improvements in and relating to the hydraulic feed system of metal and other cutting machines
Inventor: ANDERSON JAMES
Filed: 1958-04-18
Abstract: 901,354. Machine tool details. VERTIMAX Ltd. March 23, 1959 [April 18, 1958], No. 12320/58. Class 83 (3). An hydraulically-controlled copying machine comprises a first slide C moved by a piston 6 and carrying a second tool-carrying slide 43 moved by a differential piston 37, a system for simultaneously delivering fluid to the piston 6 and to the smaller side of the piston 37 and a tracer valve 27 for exhausting or supplying fluid to the larger side of the piston 37 to move the slide, or for isolating the piston 37 and causing a built-up of pressure behind the piston 6 to feed the slide C. Pressure fluid is supplied to the system by a line 17 and, at a reduced pressure, by a line 3. Pressure in the line 3 passes through a line 7 to move a valve 11 and exhaust the larger side of the piston 37 through lines 25a, 28, 23, 22, 12, 15. Pressure in the line 25b therefore moves the piston 37 downwardly together with the tracer valve body 24. When the tracer touches the pattern G, it moves upwardly to close ports 32, which are initially open by an amount adjusted by a screw 33. The closing of ports 32 seals off the larger side of the piston 37 and pressure builds up behind the piston 6 to move it forwardly. At any time, both pistons 6 and 37, or only one of them, may move. When a valve A is actuated to exhaust the line 3, the parts return to their initial positions.

Title: Improvements in or relating to drilling or like machines
IPC: B23Q1/00
Filed: 1944-06-29
Abstract: 580,309. Drilling-machines. TAYLOR, J. T. June 29, 1944, No. 12366. [Class 83 (iii)] Drilling-machines have the spindle fed by gravity acting through a cord unwound from a drum. As applied to a portable electric drill the feed is automatically stopped by arresting the fall of the weight; the motor being switched off at the same time. As applied to a portable drill for work 5, Fig. 4, the machine frame is prevented from rotating by an arm 4 and the abutment for the feed comprises a cross-head 7 connected to the work by ropes 8. Feed is applied by a drum 6 rotated by a cord 9 passing over pulleys 17, 18, Fig. 1, on a frame 16 supported by posts 15, 11 from a wheeled platform 13. The cord is connected to a support 10 guided by pulleys on the posts 11. At the end of the feed the support is arrested by projections 31 from the posts. The feed continues at reduced pressure by a smaller weight 30 during the short movement required for the weight to actuate a switch 32 for the motor. The support 10 is formed to receive additional weights 21 to enable the feed pressure to be varied as required. In a modification the feed pressure, is reduced during switching off by arresting the support 10 by yielding spring arms. A winch 22 and cord 23 passing over a pulley 24 and under a pulley 19 on the support to an anchorage on the frame 16 provides for resetting the weight.

Title: Installation comprising free piston compressors or autogenerators
IPC: F02B71/06
Filed: 1965-03-24
Abstract: 1,097,727. Free-piston compressors and gas generators. SOCIETE D'ETUDES ET DE PARTICIPATION EAU, GAZ, ELECTRICITE, ENERGIE S.A. March 24, 1965 [April 1, 1964], No.12395/65. Headings F1B and F1Q. In an installation comprising two free-piston compressors or gas generators A, B, preferably of two-stroke diesel type, the air cushion spaces 12b are inter-connected by a duct 15 containing a valve 17, and the air cushion spaces 13b are inter-connected by a duct 16 containing a valve 18. Valve 17 is opened during a part of each inward stroke of the pistons of machine A while valve 18 is opened during a part of each inward stroke of the pistons of machine B. The timing and duration of opening of each valve is so chosen that, when the difference of phase between the two machines is at the desired value, the total quantity of air transferred through the two valves from the air cushion spaces 12b, 13b of machine A to those of machine B is equal to the total quantity transferred in the opposite direction. Any departure of the difference of phase from the desired value results in an inequality between the two total quantities, whereby there is a net transfer of air from the leading machine to the lagging machine so that the lagging machine is accelerated and the leading machine is retarded. This restores the difference of phase to the desired value. Two alternative means for operating the valves are shown, each driven from the oscillating spindle 7 of the piston synchronizing linkwork of the respective machine. In one case, an oscillating cam 19 moves a piston 20 in a master cylinder 22 to actuate a piston 25 hydraulically, thereby opening the valve 17. The piston 20 is grooved circumferentially to provide a land at the inner end of the piston, and displacement of hydraulic fluid to cause opening of the valve 17 occurs only while the land covers an annular groove in the wall of the cylinder 22 during the inward stroke of the piston. The alternative arrangement comprises an oscillating cam 32 acting on the valve 18 through a tappet rod 33, the cam having separate parts (32b, 32c, 32d), Fig. 3 (not shown) arranged so that the cam follower (43) is acted on by different surfaces of the cam during the two directions of oscillation of the cam, whereby the valve 18 is opened only during part of the time that the cam is turning in one direction and remains closed while the cam is turning in the other direction. The two ducts 15, 16 may be replaced by a single duct, and the two valves 17, 18 may be replaced by a single valve operated alternately by the free pistons of the two machines.

Title: Improvements in and relating to cam-operated electric switches
IPC: H01H19/62
Filed: 1953-05-05
Abstract: 738,425. Interrupters. GENERAL ELECTRIC CO. May 5, 1953 [May 9, 1952], No. 12464/53. Class 38 (5). The " dwell " or closed time of the contacts of a cam-operated mechanical converter is adjusted by tapered thrust members arranged between the cam and the contacts so as to alter the length of the thrust-transmitting means. In one form, Fig. 3 (which shows one phase of a three-phase converter) the fixed contact pairs 19, 25 and 20, 28 are arranged to be bridged by spring-urged contacts 31, 32 respectively. A motor-driven operating shaft 47 has an eccentric portion 48 carrying a ball race 49, 50, 51 co-operating with balls 54, 55. The latter engage the tapered thrust members 56, 57, which in turn engage balls 58, 59 bearing on push rods 60, 61 which operate the contacts 31, 32. The members 56, 57 are pivoted at their upper ends 62, 63 to plungers 64, 65 which are urged down by springs 66, 67. The plungers 64, 65 pass through blocks 110, 111 secured to arms 69, 74 pivoted at 70, 75 and having openings 70a, 76 engaging an eccentric 12 on a shaft 71. The plungers 64, 65 are adjustably secured to the blocks 110, 111 by nuts 106 ... 109 so that the members 56, 57 may be individually adjusted. Joint adjustment of the members 56, 57 is obtained, during operation of the converter, by rotation of shaft 71 to pivot the arms 69, 74 and raise or lower plungers 64, 65. Shaft 71 may be rotated by hand or by a motor (not shown) responsive to the current through the converter. The push rods are biased towards the cam by springs 76, 77 and comprise insulating portions 82, 83, and metallic portions 84, 85. In a modification, Fig. 4, the portions 84, 85 directly engage the members 56, 57 which directly engage the outer ball race 51. Individual adjustment of members 56, 57 is by bolts 125 threaded into a plate 127 and acting on the ends of the plungers 64, 65. Plate 127 is vertically movable for joint adjustment of the members 56, 57 by rotation of a screw which is axially secured in a frame 123. The outer ball race may, in each arrangement, be prevented from rotating by an arm 52 and ball 53 acting in a slot, as shown. Specification 688,958, [Group XXXV], is referred to.

Title: Improvements in or relating to a controlling device
IPC: B41B27/28
Filed: 1929-04-23
Abstract: 334,499. Uher, E., and Uhertype Akt.- Ges. April 23, 1929. Monogrammic signals.-A keyboard selectively applies bodies to points on a moving support which carries them until they reach the parts to be actuated. The bodies are loosely mounted in the support and may act as circuit-closing contacts or mechanical abutments. The device may be used in controlling light or sound signalling systems and electric or mechanical switching apparatus. In an embodiment, an insulating bar 1 carries' a series of spring contacts 2. A cylindrical surface 5, which is intermittently rotated about its axle 4, is provided, in the plane of each contact 2, with a circumferential girdle of cavities 6, adapted to receive balls 7. An indined channel 8, below each girdle of cavities, feeds balls 7 to a charging point 9. The balls 7 are inserted into the cavities in a predetermined order by means of a keyboard, which has a key corresponding to each girdle. Depression of a key 12 causes a lever 16 to assume the ready position by engaging the corresponding charging pin 10 sliding in a guide 11. A pawl 18 retains the lever 16 in the ready position. The next successive depression of a key brings another lever 16 to the ready position and energizes an electromagnet 19, thus rocking the lever 21. The latter gives the first lever 16 a further motion causing the pin 10 to push the ball 9 into the corresponding cavity in the cylinder 5. A release key 25 is provided to enable an erroneous depression of a key 12 to be corrected. The balls travel round the cylinder, past the aperture 28 which provides an opportunity for correction, to the contacts 2, where they close circuits from the contacts to one pole of a battery the other pole of which is connected to the cylinder 5. After passing the contacts 2, the balls are removed from the cylinder and return to their channels 8. To retain the balls 7 on the cylinder, a hood 27 is provided. Alternatively the cylinder 5 may be a magnet. The keys 12 also cause a record strip to be printed. The keys 12 with their associated mechanism being independent of each other, a number may be depressed simultaneously as is necessary when playing a chord on a piano or in preparing a pattern surface for a jacquard loom.

Title: Improvements in or relating to Hand Method Lasting Machines for Boots or Shoes.
IPC: A43D21/02
Filed: 1916-09-07
Abstract: 109,304. British United Shoe Machinery Co., (United Shoe Machinery Co.). Sept. 7, 1916. Lasting.-To maintain more effective control of the upper by the gripper of a hand-method lasting-machine, the parts are constructed sc that the grip on the tensioned upper is reduced after the updraw, whereby the gripper. while retaining a hold on the material, grips it relatively lightly and permits the upper to slip as necessary during all or any desired part of the overdraw. The closing-bar 15* of the gripper, which is normally upraised by a jaw-opening spring 16*, is overlaid by an arm 20 of a rockshaft 22 mounted in bearings on the updraw lever and actuated from a cam 28 on the main shaft 30 through a roll carrier 25, Spring 26, and a second arm 24. A bracket 33 secured to the machine frame carries a second shaft 32 which is adapted to be actuated yieldingly through a. spring 36, sleeve 35, and a roll-carrying arm 34 from a cam 38 adjustably secured at 37 to a hub on the main shaft 30; the spring 36 is secured at one end to a collar 39, and at the other end to an adjusting-lever 42 pivoted on the shaft and having a pawl-andratchet engagement with the sleeve 35. A second arm 40 secured to the shaft 32 is forked at its free end to embrace a roll 44 on the rear side of the lever 24. In operation, the gripper is closed by the cam 28 and held during the updraw, at the end of which, instead of the gripper jaws being opened by the spring 16*. the control of the jaws is effected from the cam 38 through the arm 34, spring 36, shaft 32, and arm 40. The jaws therefore maintain a light hold on the upper, allowing it to slip through them gradually throughout the overdraw or until the upper has been entirely pulled out of the jaws. In some cases, it is desired to reduce the tension of the spring 36 when working round the toe of the shoe; this can be done by movement of the lever 42.

Filed: 1917-09-05
Abstract: 114,410. Turner, W. V. March 28, 1917. [Convention date]. Fluid-pressure. - A pilot valve 5 exhausts the pressure fluid from the upper larger surface of a differential pistonvalve 16, which is thereafter raised by the brake-pipe pressure acting on its lower surface 17. After its first movement, the additional central area of the valve 21 is acted on by brake-pipe pressure and the valve is fully opened rapidly. The brake pipe 3 is exhausted through the port 42. When the valve 16 is raised, the channel 38, through which pressure from the main reservoir 35 reached the upper side of the piston, is closed and reservoir pressure acts in the chamber 43 and serves to keep raised the valve 16 until this is manually reset by the driver. The port 44, which is opened while the valve 16 is lifted, allows the escape of any pressure fluid which may leak into the chamber 18.
