Title: Improvements in and relating to kinematograph apparatus
IPC: G03B1/56
Filed: 1937-06-17
Abstract: 497,651. Kinematograph apparatus. PATHE CINEMA ANCIENS ETABLISSEMENTS PATHE FRERES, (in Liquidation), and BRADLEY, J. June 17, 1937, No. 16898. [Class 97 (i)] A gate for kinematograph projectors or cameras adapted to employ films of different widths comprises a stationary plate 10 to which are hinged two or more plates 19, 34. The stationary plate 10 has a groove 11 for a narrow film and the hinged plate 19 has a groove 28 for a wider film. The narrow film is held in the groove 11 by projections 27 on the hinged plate 19 and the wider film is held in the groove 28 by projections 32 on the hinged plate 34. The plate 34 can be held open against the action of springs 37 by a catch 39. The plate 19 can be secured during the film-threading operation either to the stationary plate 10 or to the outer plate 34, a pin being passed through holes 18, 21, 33 for this purpose. The claw has two long forks 14 passing through a hole in all three plates to engage marginal perforations in the wider film and a short fork 15 passing through holes in the plates 10, 19 only, to engage central perforations in the narrow film. A masking aperture for the wide film is provided in the plate 34 and masking apertures for the narrow film are formed in the plates 19, 10. The larger aperture is nearer the light source and when the light is focused on the larger aperture the smaller apertures are sufficiently out of focus not to interfere with the projection of the large film.

Title: Improvements in and relating to control systems for dynamo electric machines
IPC: H02P9/02
Filed: 1943-10-15
Abstract: 598,348. Automatic speed control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 15, 1943, No. 16937. Convention date, Oct. 17, 1942. [Classes 35 and 38 (iv)] One field winding of an auxiliary brush exciter is energized with a voltage responsive to the speed of the main machine and a second exciter field winding is excited by the difference between the said voltage and a voltage proportional to the exciter armature current. The main machine may be an internal-combustion engine-driven generator and the exciter an auxiliary brush machine. In the form shown in Fig. 4, the winding 36 of exciter 28 is excited from source 76 through rectifier bridge 78-81 which is made responsive to the speed of main generator 11 by adjusting the voltage regulator 75 through cam members 73, 77, the position of member 73 being governed by an electrodynamic coupling 65, 67 on the main generator shaft, the movement of member 67 being restrained by a spring 71. The same voltage opposed by the potential across resistance 35 in the exciter armature circuit excites winding 41 and the exciter may also have a compensating winding 34 and a winding 62 fed by the transformer 63, 64. Other methods of deriving the speed-responsive voltage may be used, e.g. from a sub-exciter on the main machine shaft directly or from an alternator excited by the sub-exciter.

Abstract: 500,850. Step - by - - step conveyers. ELLIS, L. S. E. (Toastolator Co., Inc.) June 8, 1938, No. 17041. [Class 78 (i)] (Also in Group VI] In a toaster, a bread slice is rested upon a ,stationary surface and cyclicly acting means lifts it from the surface, advances it and replaces it upon the surface, means being provided for adjusting the length of the recurrent advance movements. The slice is guided by wires 12 and rests upon bars 14 from which it is lifted by a toothed bar or bars 15 carried by a member 16 guided for limited vertical and horizontal movement and provided with two openings 17, 18 of rectilinear or other suitable shape. The openings 17, 18 are engaged by eccentrics 19, 20 driven in unison by a motor 26 and worm gearings 23, 24. One of the openings is associated with a sliding member 27 adjusted by a screw 34, the effective horizontal dimensions of the opening, and consequently the magnitude of the advance step of the bar 15, being thus regulated. The member 27 is stepped so that its operative end,slides in a slot in the member 16 and the limit stop 36 is likewise in the plane of the member 16, whilst the middle portion is outside the member 16 and is guided between that member and a recessed block 28 secured thereto. The screw 34 is threaded into the block 28 and has a neck which is engaged by the forked outturned end of the member 27.

Pottery.-Relates to a modification of the process described in Specification 114,183 for annealing certain substances such as porcelain. According to the invention a rod b, Fig. 1, of the substance to be annealed is fixed by a screw c in a tube a and is bent down against a stop g by a bell-crank lever d operated by wires f attached to a lever h. The apparatus is placed in the annealing oven and the lever h is released periodically to ascertain when the rod b ceases to return to its original form. The degree of permanent distortion is indicated on a scale j and is a measure of the degree of annealing.

Filed: 1965-04-23
Abstract: 1,100,003. Telegraphy. SIEMENS A.G. 23 April, 1965 [24 April, 1964], No. 17168/65. Heading H4P. In a system wherein two subscribers are connected via the telex network, when characters SSSS are transmitted the receiver is set to operate in parity checking mode and to return those characters to the transmitter. When they are received at the transmitter it also is set to parity checking mode and data is then sent. If parity error is detected, the receiver returns the signal EEEE which causes the transmitter to cease parity operation and revert to normal. The data source, a punched tape, is stopped and an alarm operated. The operator thereupon pulls back the tape and sets up the parity checking modes as before. Then the signal EEEE is transmitted, followed by the repeated characters. The parity operation is also cancelled at the end of a message, if the tape supply fails, if no signals are received for a preset time, or if any stop bit is absent. At the end of a message the transmitter does not immediately cancel its parity mode, but waits for a time equal to the round transit time, so that any error occurring in the last few characters transmitted can be detected.

Abstract: 1,177,056. Valves. CESSNA AIRCRAFT CO. 10 April, 1968 [15 May, 1967], No. 17341/68. Heading F2V. Initial movement of a spring-centred spool 25 from the neutral position shown allows flow from inlet 11 to a chamber 48, via spool passages 36-38 and casing passage 20, to cause pistons 44, 45 to move outwards to unseat load check valves 42, 43. Subsequent spool movement connects one motor port 14 or 15 to inlet 11 and the other to its respective exhaust port 12 or 13. When the spool is returned to neutral, chamber 48 is vented through spool passages 41, 39, 40 and the check valves close. Any leakage into passages 18, 23 leaks to drain through passages 57, 58 in pistons 44, 45 and passages 41, 39, 40. A detent 53 can engage in recess 54 to define a " float " position of the spool in which both motor ports are disconnected from the inlet and connected to exhaust. The check valves can also be unseated by depression of pin 59, and can alternatively be seated by a spring and motor port pressure. In Fig. 6 (not shown), the leakage into passages 18, 23 passes to drain directly through spool passage (41).
