Title: Electrode system for cathode-ray tubes
IPC: H01J29/84
Filed: 1952-02-06
Abstract: 718,201. Ion-trapping in cathode-ray tubes. LOEWE OPTA AKT.-GES. Feb. 6, 1952 [Feb. 24, 1951], No. 3156/52. Class 39(1) In cathode ray ion trap apparatus in which the beam is given a direction inclined to the tube axis by means of an inclined electron gun or a static electric deflecting field, and a magnetic field restores the electrons to the tube axis, the magnetic field is produced by one or more permanently magnetized or magnetizable rods 7, Fig. 1A, arranged inside the tube wall and extending substantially parallel to the tube axis. As shown the first and second anodes or Wehnelt electrode and first anode have slanted ends 2, 4 to produce a static electric deflecting field component. There may be two iron or nickel rods 7 which are welded or rivetted at one end to electrode 1 and at the other end are connected to the other electrode 3 via a quartz or glass bead, Fig. 2 (not shown). The focusing coil 9 may be used to magnetize rods 7, in operation. The coil 9 is made axially moveable on the tube neck and its windings or some of them may be fed with a current which is adjustable by means of a variable resistance, so as to provide some degree of independent adjustment of the focusing and ion trapping magnetic fields.

Title: Improvements in or relating to machines for packeting tobacco or like materials
IPC: B65B11/30
Filed: 1926-02-04
Abstract: 267,671. Rose, W., and Rose Bros. (Gainsborough), Ltd. Feb. 4, 1926. Packeting by wrapping-up.-Relates to machines, for wrapping-up tobacco and the like to form rectangular packages, such as are described in Specification 22709/91. A wrapper and a charge of tobacco are fed into a mould-box 3 in a wrapping wheel 1 and are acted upon so that the wrapper covers three sides of the charge, the top portion 8 being then laid across the upper surface.

Title: Improvements in electric motor and like controllers
IPC: H01H19/11
Filed: 1945-02-08
Abstract: 586,416. Ratchet gearing. MORRISON, A. C. Feb. 8, 1945, No. 3191. [Class 80 (iii)] [Also in Group XXXVII] A shaft (e.g., that of an electric motor controller) is rotated step by step by a rotary part 3, Figs. 1 and 2, associated with locking means normally engaging an adjacent relatively fixed member to prevent rotation and with a trip member movable (e.g., by a pedal) through a yieldable connection and a dashpot, windvane, or other delay-action' device to release the locking means and so allow of a step of movement in either direction. The forked locking arm 5 pivoted at 6 on a part 3 carries a roller 7 normally held in a groove 8a in a fixed ring 8, as in Fig. 3, by a spring-pressed plunger 15, Fig. 2, acting on the tail-piece 5e of an arm 5. When the trip member 9 is rotated in either direction one of its projections 9a and 9b urges the roller 7 out of the groove 8a while one of its surfaces 9c and 9d compresses one of the springs 13 through a plunger 12 or 12'. When the roller 7 is lifted clear of the ring 8, the spring 13 quickly turns the part 3 through one step; the roller 7 is then urged into the next groove partly by the action of the plunger 15 on the tail-piece 5e and partly by engagement of the latter with the further projection 9e from the member 9. The pedal or handle can move member 10 against the force of a spring 30 to drive the member 9 through a yielding spring 27 bearing against an eye-piece 24 pivoted at 25 to an arm 26 formed on the member 9. Motion is delayed in one direction by a piston 31 moving in a dashpot cylinder 32 and mounted on a rod 33 secured to an eye-piece 34 also pivoted to the arm 26 at 25; in the other direction, a valve plate 35 uncovers ports 36 in the piston 31, topermit rapid return.
Patent GB-765245-A (GB)
Title: Teleprinter machines having alternatively operable transmitting arrangements
IPC: H04L13/06
Filed: 1955-02-03
Abstract: 765,245. Printing-telegraph transmitters. SIEMENS & HALSKE AKT.-GES. Feb. 3, 1955 [Feb. 3, 1954], No. 3266/55. Class 40 (3). A teleprinter having a transmitting arrangement operated by a keyboard or by a perforated tape, according to choice, includes a change-over arrangement dependent on a tapeexploring member in such manner that the change-over from perforated-tape operation to the condition for keyboard operation takes place automatically in the event of an interruption in the tape. The absence of tape may be due to tearing or to the exhaustion of the supply of perforated tape. For tape operation, the shaft 17 is in the position shown in which it is latched by a pivoted detent 13 and positions a member 18 so that the transmitter shaft 19 is permitted to rotate continuously. During each revolution of the shaft 19 a cam 27 rocks a lever 24 carrying a pin 23 engaging a rod 21 which is rotated so that its upper end slides on the end portion 6 of a feeler lever 4 mounted on a stirrup member 5. The opposite end of the lever 4 lightly engages the tape 1 through a window 3 in a guide member 2. When the tape supply is interrupted the feeler 4 is rocked clockwise by its spring 7 so that the rod 21 when subsequently actuated under control of the cam 27 engages the end portion 6 and rocks the stirrup 5 so that its projecting member 11 rocks the detent 13 clear of a toothed lug 16 on the shaft 17 which is rotated clockwise by a spring 15. The rotation of the shaft 17 actuates the member 18 so that the shaft 19 is brought under the control of the keyboard and is released for one revolution on each actuation of key lever. Additionally, the movement of the cam 31 allows the lever 28 to move so that a lateral extension 29 rocks the rod 21 out of operating range of the pin 23 on the lever 24. The machine is restored to tape operation by anticlockwise rotation of the shaft 17 by a knob 20. The change to keyboard operation may be effected manually by moving the shaft 17 axially against the action of a spring (not shown) so that its rotation is effected by the spring 15 after disengagement of the toothed lug 16 from the detent 13. Specification 680,633 is referred to.

Title: Automatic adjuster for brakes, clutches and the like
IPC: F16D13/75
Filed: 1957-01-30
Abstract: 804,826. Brake automatic adjusters. BENDIX AVIATION CORPORATION. Jan. 30, 1957 [March 21, 1956], No. 3316/57. Class 103 (1). [Also in Group XXIV] An automatic adjustment device, which although shown applied to a disc brake, may be used equally well on other forms of fluid pressure actuated brake, comprises a pressureresponsive element 14 reciprocal in a bore in a fixed carrier member 12 and having secured to its end friction element carrier plates 22, the element 14 having an inner bore therein, within which slides a positioning member 28. The positioning member 28 is normally moved by the piston element 14 in the brake applying direction by a friction ring 34 therebetween until a sleeve 54 within the member 28 abuts the boss 46 on the end of a stem 42 secured at its end 44 to the fixed carrier member 12, the spring 50 being compressed during this movement. On release of the brake the spring 50 expands and moves the member 28 and piston element 14 back through the distance D to reset the clearance. If at any time the clearance between friction members 22 and 24 is reduced below the proper amount application of fluid pressure behind piston element 14, first moves the piston element and friction member 22 to bring it into engagement with member 24 and then acts on the inner end of member 28 to move the member forward relative to the member 14. Thus, when the brake is released, after only a single brake application, the clearance is always restored to the correct amount. Fig. 5 shows a similar arrangement in which the friction ring 34c is adapted to slide in the bore of the hollow piston member 14c, being wedged against a projection on the member 28c by a clamping nut 36c.

Title: Improvements in and relating to starting apparatus for electric discharge lamps
IPC: H05B41/10
Filed: 1942-03-16
Abstract: 556,112. Electricity supply to discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. March 16, 1942, No. 3421. Convention date, March 18, 1941. [Class 38 (iv)'] The starting "kick" for a discharge lamp 1 is produced, after the electrodes have been adequately heated, by the opening of the thermal switch 6 ; this energizes the coil 16 in parallel with the switch with the result that the armature 17 is attracted breaking the heating circuit (which includes the heater 13 of the switch 6) at 21, 22, rapidly, to give the starting impulse. When the lamp is started the thermal element, which is in two parts, one part 11 heated by 13 and the other set in the opposite direction to compensate the element as a whole for variations of ambient temperature, re-approaches the fixed contact but is prevented from actual engagement by a shoulder on the attracted armature. The armature is released if the supply fails.

Title: Improved arrangement for measuring the temperature of solid particles
Inventor: BLAKE LESLIE REGINALD
IPC: G01K13/02
Filed: 1956-02-03
Abstract: 831,144. Measuring temperature. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 11, 1957 [Feb. 3, 1956], No. 3474/56. Class 40 (1). The temperature of flowing solid particles is measured by passing them in a stream around a temperature-sensing member which is mounted on a resilient support so that it can move parallel or at right angles to the flow. Fig. 1 shows an arrangement for measuring the temperature of stone chippings which are heated in a drum 2 revolving anticlockwise about its centre. The conical passageway 1 does not rotate and serves to concentrate the particles around the sensing element 3 (e.g. a thermocouple or thermistor). The latter is sealed in a heat-conducting abrasion-protective casing and mounted on a plate 13 for good thermal contact with the particles. The resilient mounting is a spring 4 through which the leads pass, and (Fig. 2, not shown) it may be mounted in a hollow tube. The electrical signal may be passed to an indicator, or may be used to control the flow of material or the rotation of the drum. In a continuous heater the particles flow along an inclined drum with the member 1 outside.

Title: Improvements in Apparatus for Making and Applying Caps to Bottles and the like.
Inventor: NORDSTROM ELOF
IPC: B67B3/02
Filed: 1916-08-30
Abstract: 106,273. Nordstrom, E. Aug. 31, 1915, [Convention date]. ' Crown corks ' and the like, applying.-In apparatus for making bottle-caps and applying them to bottles or other vessels, the cork inserts 152, Fig. 11, are fed one at a time from the bottom of a shoot 151 by a slide 149 into the path of a plunger 153, and, after receiving a cork from the plunger 153, the cap is brought by a rotary table 114 over the mouth of a bottle 166, Fig. 4. The bottle is held by pivoted grippers 167 provided with arms 168, Fig. 3, which are geared together and one of which is carried by a sleeve 169 having an arm operated by a cam. The cap-applying plunger 203 is actuated by a lever 205 and rod 207 connected by a lost-motion coupling 208 to a rod 209 operated by the lever 107. If a bottle is not presented to the capping-mechanism, a feeler 173 at the lower end of a rod 174 is moved inwards by a spring and an arm 175 disengages the pawl 66 from the shoulder 69, thereby throwing the cap-constructing mechanism out of gear The bottles &c. are fed one at a time to the capping-mechanism, and the capped bottles are fed in pairs to the crimping-mechanism. The crimp. ing-head is carried by a slide 217, Figs. 3 and 17, reciprocated in a guide 218 by a cam 214 on a shaft 213 driven by bevel-gearing from the shaft 58, Fig. 4. The spring-pressed crimping-elements 228, Fig. 12, project through radial slots in a spring-pressed slide 222 carried by a rod 224 which passes through the upper end of a socket 221 carried by the slide 217. An adjustable nut 225 limits the downward movement of the rod 224. When the socket descends, the member 227 rests on the cap on the bottle, and when the slide 222 is brought to rest, the spring-pressed plungers 232 are forced down on to the elements 228 causing them to turn about their rounded lugs 229 and crimp the cap. The bottle-clamping levers 236 carried by the guide 218 are normally drawn together in pairs by springs 237, and are provided with interengaging segmental arms 238. Lugs 239 projecting from the front lever of each pair are engaged simultaneously by a bar 240 connected by straps 241 to the slide 217. The means for feeding cork inserts described in Specification 106,272 may be used in the machine. Specification 101,351 is referred to.

Title: A new or improved means for relieving the compression in the cylinders of internal combustion engines at starting
IPC: F01L13/08
Filed: 1935-02-08
Abstract: 451,428. Starting. BLACKSTONE & CO., Ltd., CARTER, W. E., and JACKSON, P., Rutland Engineering Works, Stamford, Lincoln. Feb. 8, 1935, No. 4064. [Class 7 (v)] Starting is facilitated by a device for relieving cylinder compression which is rendered inoperative after a predetermined number of rotations of the engine by means of a step-by-step mechanism operated by the normal periodic movement of a part of the normal valve-actuating mechanism. As shown, a snail cam a is mounted on a shaft g alongside the air or exhaust valve lever d, and can be turned to a position in which the valve e is held open. A disc b on the shaft g is formed with ratchet teeth for engagement by a pawl c pivoted on the valve lever d, and a spring-pressed plunger f bears against the disc b. As the engine is turned, the movement of the valve lever d turns the shaft g step-bystep by means of the pawl c, so that after a predetermined number of engine revolutions the lever d falls into the recess h of the snail cam and normal compression is restored. When the movement of the disc b has been completed, the plunger f falls down the incline t and holds the gear out of operation. For a multi-cylinder engine, a snail cam a acts on the valve lever d of each cylinder and the snail cams may be arranged to restore compression in individual cylinders in any predetermined order. In a modification, the pawl c is acted upon by a spring coiled around its pivot and the plunger f is replaced by a projection on the lever d. In a further modification, the pawl c is pivoted on a valve push-rod and the snail cam a actuates through a lever a slide bar acting upon each valve push-rod through a lever.
