Title: Improvements in or relating to postal franking machines
Inventor: MUELLER WILHELM
IPC: G07B17/00
Filed: 1952-09-09
Abstract: 706,898. Franking machines. TELEFONBAU UND NORMALZEIT GES. Sept. 9, 1952, No. 22604/52. Class 100 (2) A franking machine comprises a printing roller 18 for printing a franking stamp on matter to be franked, the drive of the printing roller being controllable by an electric control circuit having a main contactor in series with an auxiliary contactor 9 which is operable by the matter to be franked when fed through the machine to prepare the control circuit, the main contactor being operable at regular time intervals by a motor 3 for driving the printing roller, to open and close the circuit so as to print franking stamps at regular intervals on a strip of material fed through the machine. The motor 3 drives a conveyer 4 for the matter to be franked, a shaft 21 driving the roller 18 through a dog clutch 15, 20 and a main-contactor cam shaft 17 through reduction gearing 16. The shaft 17 carries cams 32, 33, 34 operating main-contactors 35, 36, 37 respectively. The clutch part 15 is continuously driven whilst the part 21 is spring- biased for operative connection but normally kept out of engagement by a lever 24 so that until operation of the lever 24 the roller 18 remains stationary. A subtracting counting mechanism 40 controlled by a cam 38 on the shaft 21 is provided and maintains a switch 43 closed until the desired number of franking operations has been completed. When it is desired to print on individual envelopes the envelopes are stacked on a table 5 removably mounted on the frame 1 of the machine and are fed to the conveyer 4, the main contactor switch 50 being set in the position shown in Fig. 3. The envelopes are detected by a feeler 26. The auxiliary contactor 9 comprises a mercury switch having a main contact 31 on an iron arm 29 and held out of engagement with the liquid contact 30 by a permanent magnet 28. Operation of the feeler 26 moves the magnet 28 out of range of the arm 29 and the switch makes contact thereby energizing an electromagnet 23 which in turn causes operation of the lever 24 so that the roller 18 makes a franking revolution. When it is desired to print on a strip of material the table 5 is replaced by a web roll holder 6. The switch 50 is set in a position so as to select one of the circuits passing through contacts 35, 36, 37 depending on the frequency at which a franking stamp is desired to be printed on the web. Since the web is continuous the feeler 26 is continually operated and the auxiliary contactor 9 remains closed. Energization of the electromagnet 23 therefore takes place under the control of the selected one of switches 35, 36, 37, operated by cams 32, 33, 34. Each time the roller 18 prints a franking stamp the web is severed on emerging from the machine by a cutter device 8 which is also controlled through linkage by the electromagnet 23. The counting device is set at the number of franking stamps required and when this number has been reduced to zero the switch 43 is opened thereby stopping any further printing operation.

Abstract: 835,067. Toy guns. METTOY CO. Ltd. July 17, 1958 [July 17, 1957], No. 22635/57. Class 132(3) The forward part of a barrel of a toy gun accommodates a number of ball projectiles 7 which are urged forwardly by a light spring 8 such that the front ball is held against a synthetic rubber diaphragm 10 having a central aperture smaller than the balls. A piston rod 14 is normally urged forwardly by a spring 15 and the rear part of the piston rod is cranked downwardly for the part 14b to slide in guides formed in the stock 4 and the part 14a to lie between a pair of plate members 17, 18. An enlargement 24 on the rear part of the piston rod engages behind a shoulder on a lever 25 when the piston rod is moved rearwardly by a bolt rod 19; the lever is connected to a trigger 29. The gun is loaded by forcing the balls 7 successively through the aperture in the diaphragm 10 and is cocked by drawing the bolt rearwardly by a knob 23, the bolt returning forwardly by a spring 20. On pulling the trigger, the piston rod is released and is driven forward until arrested by a rubber buffer 30. The air compressed by the forward movement of the piston forces the front ball against the diaphragm and through the diaphragm aperture. The remaining balls are moved forwardly by a spring 8 ready for discharging in turn.

Title: Improvements in and relating to systems of electric motor control
IPC: H02K17/40
Filed: 1933-08-15
Abstract: 424,136. Induction motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and ADKINS, B., 13, Fisher Avenue, Paddox, Rugby. Aug. 15, 1933, No. 22806. [Class 35] In a speed control system for an induction motor, a commutator machine is provided to apply a voltage of slip frequency to the secondary circuit of the motor and to act alternatively as a machine having a low frequency output for feeding the induction motor during low speed operation. The secondary of a motor 2 is connected through slip rings 3 to the commutator 8 of a regulating machine 6 in series with a compensating winding 7. The machine is coupled to a motor 10 running at approximately constant speed. The exciting winding 9 can be fed either from a variable auto-transformer 12 connected in shunt to the slip rings 3 or through a switch 16 directly in shunt in series with a rheostat 17. The auto-transformer circuit also includes a frequency changing exciter 13. For the upper part of the speed range, the main motor is connected to the supply, switch 16 and the rheostat 17 are opened, switches 11, 18 are closed and the speed is controlled by varying the taps on the autotransformer. For the lower part of the speed range, the primary circuit of the main motor is disconnected from the mains and short-circuited through a switch 5. Switch 16 is closed and switches 11, 18 are opened so that the regulating machine 6 acts as a low frequency generator feeding the main motor, the speed being controlled by means of the rheostat 17. The machine 6 may be of the type described in Specification 420,230 and the main motor 2 and frequency changer 13 may be combined as described in Specification 402,498. In a modification, the machine 6 is replaced by a continuous current machine the brushes of which are connected to the commutator brushes of a rotary converter, the slip rings of which are connected through switches controlling the direction of phase rotation to the slip rings of the main motor. The speed can be varied down to about half the synchronous speed by varying the field of the continuous current machine. For low speed operation the main motor primary winding is disconnected from the mains and short-circuited, and the phase rotation of the connections between the main motor and the converter is reversed so that the continuous current machine acts as a generator feeding the rotary converter which supplies low frequency current to the secondary of the main motor. Specifications 19362/11 and 140,476, [both in Class 35], also are referred to.

Title: Improvements in typographical linecasting machines
IPC: B41B27/10
Filed: 1957-10-11
Abstract: 878,944. Type-bar-making machines. ASTIER, P. J. B. Oct. 11, 1957 (Oct. 17, 1956; Jan. 15, 1957], No. 22865/61. Divided out of 878,943. Class 100(3) A typographical machine of the kind having a keyboard to assemble a line of matrices from which a type-bar is cast is provided with means for being automatically controlled from a perforated tape, said means comprising a series of spring-biased bars, in notches of which engage feelers which normally lock the bars, the feelers being periodically raised to feel the tape, any feeler which penetrates a tape perforation disengaging from its notch to free its associated bar to bear, under its spring load, against a rotating cam so as to be reciprocated thereby, and a series of notched keys each urged by a spring towards a rotating cam, but normally held locked by fingers engaging in their notches, a selected key being freed to allow it to follow the cam movement by operation of the fingers under. control of the reciprocal movement of the bars, the movement of the notched key being translated to a keyboard key of the machine so as to cause the normal functioning thereof. A shaft 107, Fig. 1, is rotated from the casting machine, and a cam 126 acts to raise feelers 100 against the control tape P. Any feeler which passes through a hole in the tape releases a bar 105 to be urged by a spring 108 against a cam 106 and reciprocated thereby. Reciprocation of a combination of bars 105 raises selected bars 125, 124 to release one of a series of keys 112, which is spring-urged against a cam 106a and reciprocated thereby, its movement being translated through a rod 117 to the corresponding key 417 of the keyboard of the casting machine to actuate it. The cam 126 also causes rotation of a ratchet wheel 133 to feed the tape. When the assembling elevator begins to rise, it energizes an electromagnet X, to stop the tape feed. Certain additional keys 112a actuate electrical contacts 144 to carry out special functions e.g. quadding. An end-of-line signal energizes a magnet E 14 , Fig. 4, to release a block 427 on a which 439, which is first rotated by a counterweight 431, rotation being continued by a roller 432 on the shaft of the normal keyboard roller 434, the roller 432 engaging a milled periphery of the wheel. A pin 435 on the wheel acts on the elevator raising handle 436.

Abstract: 288,591. Still, C. April 13, 1927 [Convention date]. Tar oils, purifying.-Benzol fractions are treated directly after their production, before any oxidation can occur, with caustic alkali to free them from sulphur. The light oil or crude benzol or motor benzol or crude toluol may be improved by rectification and washed continuously with aqueous caustic alkali as it is produced.. Preheated wash oil charged with benzol enters by a pipe e a distillation column a heated by steam at h, and the gas passing through a dephlegmator b enters a condenser c 'having means h to withdraw water at the bottom. Light oil passes out at m and is mixed continuously in the pipe o with a solution of caustic soda added through the pipe n, the mixture next entering a centrifugal pump r, whence it is led to a separator t with inspection pots w, v for drawing off benzol and caustic soda solution.

Abstract: 1478928 Scanning systems INTERNATIONAL BUSINESS MACHINES CORP 23 May 1975 [1 July 1974] 22924/75 Heading G2J [Also in Division G4] A beam, e.g. from a laser 20, is scanned by a moving mirror, e.g. a polygonal rotating mirror 26, on to an array of fixed reflectors, each fixed reflector being so orientated as to provide a discrete scanning beam, falling on scanning station 35, which is spatially separated from the scanning beams from the other reflectors. As shown, Fig. 1, the planes of the separate reflectors 91-98 are all intersected by a line 31 which is parallel to the plane of the scanning station but set at an angle to the long axis of the scanning station. Beams from the end mirrors 91, 92, 97, 98 suffer an additional reflection at 36 to produce discrete beams which intersect the beams from mirrors 93-96 at an angle. A preferred angle is 45 degrees. A plurality of scanning patterns such as that shown at station 35 may be interlaced by providing a plurality of beams incident on the rotating polygon at different angles, e.g. by means of beam-splitters 114, 116, 118. The array of mirrors 91-98 may be replaced by a staggered array of fixed mirrors, each of which deflects the beam through 90 degrees. The system is intended for scanning bar coded labels on merchandise as they are passed before windows 35. Reflected light is detected at 36, 38 and processed.
