Abstract: 670,882. Shoes. STANDARD ENGINEERING CO., Ltd. May 19, 1950 [June 1, 1949], No. 14735/49. Classes 17 (i) and 17 (ii). Light flexible shoes are made by attaching an upper to an upstanding lip formed round the periphery of a light flexible insole held firmly on the last during such attachment at least round the full length of the lip. The last may have a recess in its face bounded by a lip b into which the insole is forced and held by a plate d of rigid material so as to form the upstanding lip c<SP>1</SP>. Instead of a plate d, a wire frame may be used to hold the insole in position. The upstanding lip may be formed by a moulding operation, in which case the last need not be recessed on its face, or by turning up the edges of a flexible insole secured by means of a plate, to the face of the last. The invention may be used in the manufacture of welted shoes or of platform type footwear, the upper being attached to the insole e.g. by staple lasting or a bed lasting machine and a welt or a platform cover attached and the shoe completed in usual manner. Specifications 17993/11, [Class 17 (ii)], and 600,660 are referred to.

IPC: G10K13/00
Filed: 1916-10-18
Abstract: 107,144. O'Gorman, M. Oct. 18, 1916. Diminishing " scratch " by vibrating the sound-box; producing tremolo; sound-boxes, mounting.-A talking-machine tremolo effect is produced at will, either during the formation or reproduction of the record, by giving the) recording tool or reproducing needle a vibratory movement along the sound groove. A limited up- and-down vibratory ' movement also may be given, and this is stated to diminish friction and " scratch " during reproduction. As shown in Fig. 1, a sound-box c and needle h are supported on the tone arm d by a flexible connexion e or other joint designed to allow the necessary movement without chatter. A motor with an outof-balance fly-wheel n and carried on a hinged table t is connected to a lever by a wire connexion m which is normally slack, the lever g being held against a padded stop x by a spring s. When the connexion m is made taut by depressing the table t, the vibrations of the motor are communicated through the lever g and a wire or pivoted link f to the sound-box. A modification is described in which the lever g is vibrated directly by the finger. The pivot of the link f is preferably low as shown. Two or more vibrating tables of different period may be provided. Up and down movement may be given by a direct connexion between a vibrating table and an extension of the link f (not shown). Alternatives are described in which the record-carrying table is vibrated. In conjunction with the tremolo arrangement, the volume of sound may be controlled by an obturator or by pinching the flexible connexion. The effects may be controlled from a distance by a suitable key-board and connexions.

Abstract: 601,053. Electric detectors of surface irregularities. JACK & HEINTZ RESEARCH CORPORATION. Aug. 2, 1944, No. 14793. Convention date, Aug. 2, 1943. [Class 40 (iv)] [Also in Groups XIX and XXXVIII] An electrical pick-up for indicating irregularities in a surface comprises a primary coil with coaxial pick-up coils on opposite sides of the driving coil and two spring arms arranged to hold a coaxial armature in a position symmetrical with respect to the pick-up coils, a stylus being attached to one of the spring arms and effecting movement of the armature from a reference position when irregularity on the surface is encountered. As shown in Fig. 1, the stylus 21 is carried by the spring arm 10 attached to the armature 11 which is also connected to the spring arm 9 secured to an insulating casing 1. Oppositely wound coils 2, 4 are connected to contacts 6, 7 and the primary coil 3 connected to contacts 7, 8 is fed with alternating current from an oscillating circuit, Fig. 3, comprising a positive feed-back network C1, R1, C2, R2, determining the oscillation frequency and a negative feed-back network R3, R4 to stabilize the oscillator. The differential voltage produced in the coils 2, 4 is fed through a step-up transformer 33 to valves 36, 38 and a recording milliameter 35. The plate, grid and filament voltages for the valves of the oscillator and for the valves 36, 38 are obtained from a source 25, a rectifier 30 and a tuned circuit 31, 32. In the use of the instrument the stylus and armature 11 are displaced by a standard surface so that the needle 41 of the ammeter 35 occupies a central or artificial zero position and irregularities on the work surface are indicated as deviations to the right or left of the zero position. The instrument may be used to investigate irregularities on a curved surface, Figs. 4, 5, 6 (not shown), the work piece being mounted on a table which is adjustable in two directions at right angles and the pick-up mechanism being carried on a rotatable shaft which may be adjusted to suit different radii of curvature. In a modification, Figs. 7, 8 (not shown), the pick-up is carried on a frame having three spaced feet with the stylus projecting through an aperture in one of the feet. In a further modification, Figs. 9, 10 (not shown), the stylus member comprises a ball which engages the surface and which is located centrally with regard to three supporting feet.

Abstract: 549,985. Sulphones, LILLY & CO., E., KHARASCH, M. S., and REINMUTH, O. Oct. 4, 1940, No. 14892. [Class 2 (iii)] Therapeutically useful compounds are prepared by reacting 4:4<SP>1</SP>-diaminodiphenylsulphone with a saturated or unsaturated aliphatic aldehyde containing not more than 3 carbon atoms and an unsubstituted mercaptocarboxylic or mercapto-sulphonic acid. The two latter reactants are employed in such quantities that substitution takes place at either one or both of the amino groups in the sulphone. The sulphone may first be reacted with the aldehyde and the resulting condensation product then treated with one or two equivalents of the mercapto acid. The products may be converted into their salts with alkali and alkaline earth metals, ammonia, alkylamines, alkanolamines and polymethylenediamines. Examples are given of the treatment of 4:4<SP>1</SP>-diaminodiphenylsulphone (1) with formaldehyde and mercaptoacetic acid, #- mercaptopropionic acid, α-mercaptopropionic acid, 4-mercaptobenzenesulphonic acid, #- mercaptoethanesulphonic acid or 2-mercaptobenzoic acid, the amount of formaldehyde and mercapto acid being sufficient to combine with one or both the sulphone amino groups; (2) with one or two equivalents of acetaldehyde or acrolein and of mercaptoacetic acid ; the products are converted into their sodium salts. The preparation of N:N<SP>1</SP>-dimethylene-4:4<SP>1</SP>- diaminodiphenylsulphone from 4:4<SP>1</SP>-diaminodiphenylsulphone and formaldehyde is also described.
Patent GB-164322-A (GB)
Title: Improvements in animal traps
IPC: A01M23/30
Filed: 1921-05-30
Abstract: 164,322. Kroon, J. P. H. May 30,1921. Animal traps. - A throw-over trap of the type having a bait-lever 3 which rests upon the bait 4 and controls a locking lever 2, has the arms of the bait-lever of unequal length and provision is made to allow the long arm which rests on the bait to turn when released without contact with other parts of the trap. In one form a slot 5, Fig. 1, in the base of the trap allows the long arm of the bait-lever 3 to move downwardly. In another form the bait may be arranged on an elevation so placed that the bait-lever passes behind it. The bait-lever may be loosely attached to the locking lever 2 and engage under a cross-bar which replaces the pivot 17<a>. In another form the baitlever is formed as a frame which loosely surrounds the cross-bar 9, Fig. 3, which engages with a shoulder 21 in the set position. When released the bait lever can move inwardly. This form may be modified by making a recess at the angle 22 in which the cross-bar 9 fits when the trap is not set. This allows the lever 2 to be locked by the bait-lever while the bait is placed in position. In another form, a link 10, Fig. 4, attached to the locking lever 2 slides over an inclined surface 11 formed on the bait-lever 3, and engages beneath the bait-lever without tilting it. A projection such as 14, Fig. 1, is engaged by the striker frame 1 when the latter is moved to the set position and brings the locking-lever 2 automatically into the set position. Additional levers may be interposed between the bait-lever and the locking lever, and the spring 16 may be made in two parts leaving a central space to accommodate the train of levers. The bait-lever may be arranged parallel to the axis of the spring 16, the pivot being near one side of the trap. The locking-lever is then bent to correspond and is prevented from moving laterally by means of a V- shaped guide. A stop such as 13, Fig. 4, is provided to limit the rise of the long arm of the bait-lever, so that the lever always falls by gravity into the horizontal position. According to the Specification, as open to inspection under Sect. 91 (3) (a), the bait-lever may be curved and accommodated in a slot passing beneath the spring 16. This subject-matter does not appear in the Specification as accepted.

Title: Chewing gum having controlled flavour release
Inventor: KALAFATAS NICHOLAS JOHN
IPC: A23G4/20
Filed: 1959-05-01
Abstract: A chewing gum comprises a water-immiscible flavouring, e.g. oil of wintergreen, peppermint, or spices, liquorice, or fruit juices, enclosed in finely-divided particles of gelatine or plastic gum base, e.g. chiele, rubber, jelutong or natural or synthetic resins or waxes and plasticizers, e.g. glycerine and sweeteners, e.g. sucrose or dextrose or cyclamates or saccharin &c.  The gelatin may be hardened by various agents.  As an example, 20 parts of weight of gum arabic are dissolved in 160 parts water and 80 parts of oil of wintergreen added, and emulsified and mixed with 20 parts gelatine dissolved in 160 parts of water.  After drop by drop addition with agitation coacervation begins and is continued until the particle size of the oil droplets is as large as desired all at 120 DEG  F.  This mixture is poured into water at 32 DEG  F. to bring the total weight to 4,000 parts which is then agitated and allowed to stand for 1 hour at less than 77 DEG  F. to form a solution containing the enclosed flavouring.  This may be hardened by adjusting the pH of the coacervate to 9-11 with NaOH and allowing it to stand for 30 minutes; 19.8 parts of a 37% aqueous solution of formaldehyde previously adjusted to pH 9-11 is added to the coacervate and the mixture is agitated for 10 minutes at 37 DEG  F. or less.  The result is filtered dried and comminuted and added to chiele or other chewable agent.
Patent GB-476293-A (GB)
Title: Improvements in or relating to mowing machines
IPC: A01D34/26
Filed: 1936-05-28
Abstract: 476,293. Mowing - machines. VILLE, A. W. DE, KITCHEN, A. E., and RUSTON & HORNSBY, Ltd. May 28, 1936, No. 15073. [Class 6 (iii)] A power mower is provided with poweractuated means for raising the cutter bar actuated through a clutch which is adapted to be disengaged automatically when the cutter bar reaches its raised position. A power shaft 4 driven from the power take-off shaft of the tractor has splined thereon a sleeve 10 provided with teeth adapted to be moved into engagement with co - operating teeth 8 on a sleeve 9 free to rotate on the shaft. The sleeve is moved into and out of operative position by a lever 11 adapted to be moved in the one direction by a cord 22 and in the other by a spring 20. A trigger lever 34 pivoted on the lever 11 passes at its rear end through a slot 38 in a latch plate 39 and is provided with a shoulder 40 that may engage on the front side of the latch plate. The front end of the bar 34 is pulled downwards by a spring 36 and carries a roller 37 that bears against a double cam 33 on a shaft 24. The sleeve 9 is formed with a worm 7 engaging with a worm wheel 23 keyed to the shaft 24. This shaft carries a crank 25 connected by a rod 26 to a bell-crank 28 connected by a chain 31 to the usual lifting gear, the crank and the bell-crank being so arranged that in both the raised and the lowered positions of the cutter bar the pivots are practically in line. On pulling the cord 22 the clutch is thrown in starting the worm 7 and driving the shaft 24 and also causing the trigger bar 34 to move forward with its shoulder 40 clear of the latch plate 39; as the roller 37 on the latch bar passes over the raised part of the cam 33, the bar is pulled downwards by the spring 36 so that the shoulder is in position to engage the latch plate 39 and thus to hold the clutch engaged even though the cord 22 is released. When the shaft 24 has turned through half a revolution, thus raising or lowering the cutter bar, the trigger bar 34 is lifted bv the cam 33 so that the shoulder 40 is moved below the latch plate, the clutch then being opened by the pull of the spring 20 on the lever 11. The end 47 of the shaft 4 is squared so that a handle may be fitted for hand operation of the shaft. A bracket 46 on the lever 11 moves into position at engage stops 43 on the sleeve 9 to lock this sleeve when the clutch is disengaged.

Title: Inking systems for offset printing and duplicating machines
IPC: A47C27/06
Filed: 1959-05-06
Abstract: 867,623. Inking-apparatus. GERICKE, E. May 6, 1959 [Oct. 31, 1958], No. 15516/59. Class 100(2) An offset printing-machine comprises an inking system in which each alternate inking roller is mounted in the machine frame while the other rollers are mounted in a roller frame which can be tilted about a fulcrum on the machine frame, a guide pin on the machine frame is arranged to lock the roller frame in position, and a control lever is provided for arresting the roller frame in various positions, the control lever having a forked member which is so positioned with respect to the guide pin that in a first position it engages or releases the pin, while in the remaining positions it slides over the pin and thus locks the roller frame in its various positions. The rollers 8, 10, 12, Fig. 3, are supported on a roller frame 1 carrying a shaft 14 on which is pivoted a control lever 2 with a forked portion 6 co-operating with a fixed pin 7. A pin 3 on the lever engages in one of a number of grooves in a quadrant 4 also carried on the frame 1. In position III shown, the rollers are in contact with the fixed rollers 9, 11 and the rollers 8, 10 with the printing cylinder. In position II, the rollers are out of contact with the printing cylinder while in contact with the fixed rollers. In position III, the portion 6 can be drawn clear of the pin, so that by means of the lever 2 the frame 1 can be swung upwards through about 180 degrees until retained by an abutment 13 on the machine wall 23. When the pin 7 and portion 6 are out of engagement, the shaft 14 and lever 2 are prevented from movement relative to the frame 1 by mechanism at the opposite end of the shaft 14. As the portion 6 leaves the pin 7, a fork member 6<SP>1</SP>, Fig. 6, leaves a fixed pin 71, releasing a lever 17 mounted on the shaft for movement limited by a pin 22 on the member 6<SP>1</SP>. A spring 18 then moves a catch 16 pivoted at 20 on the frame 1, displacing a stud 19 on the lever 17, until a recess in the catch engages a pin 15 on the shaft and locks it. If the catch 16 fails to move into locking position, a fixed abutment 24 engages it and prevents raising of the frame 1.
