Title: Improvements relating to dynamometer apparatus for testing internal combustion engines
IPC: H02K49/06
Filed: 1930-10-25
Abstract: 360,178. Rotary-absorption dynamometers. HIGHFIELD, F. W. W. and HIGHFIELD ELECTRICAL CO., Ltd., Faraday Works, Stoney Stanton Road, Coventry. Oct. 25, 1930, No. 32111. [Class 106 (ii).] Relates to electrical apparatus as in Specification 322,394, [Class 106 (ii), Dynamometers &c.], and consists in an alternating current generator a coupled to the engine b and supplying the whole of the current generated to an ordinary induction motor c which drives a fan f for cooling the engine. The generator is preferably carried on pivotal supports so that torque reaction may be used to measure the power developed. Any convenient regulating means connected to the slip rings may be employed for the rotor of the motor. As the power absorbed by the fan is usually much less than that developed by the generator, the rotor is run at less than synchronous speed, the loss of power supplied being dissipated in the regulating means. If it is desired to use the excess energy, the regulating means is arranged in combination with a rectifier or converter or other means for rendering such energy available for use.

Title: Concertina type sheet folding machine
IPC: B65H45/14
Filed: 1971-07-08
Abstract: 1349558 Folding paper D RODA 8 July 1971 [14 July 1970] 32149/71 Heading B8R A sheet 2, Fig. lb, is placed on a table 1 and moved along it until the front end passes beyond the table and also under a blade 5 which prevents reverse movement. When the front end passes a photo-electric device 13, a motor starts to rotate rollers 10, 11a, 11b, for instance in the directions opposite to the arrows C, E. When the front end is pushed against the roller 10, it is carried through the nip between the rollers 10, 11a, until it reaches a photo-electric device 12a, which reverses the motor so as to rotate the rollers according to the arrows, and the end portion 2a of the strip moves backwards to form a loop 2b, which is pulled between the rollers 10, 11b to form a first fold. When the fold reaches a photo-electric device 12b, the motor is reversed and the process is repeated to form a second fold, until the whole strip is zig-zag folded. When the trailing end clears the device 13, the devices 12a, 12b no longer reverse the motor, so that the folded pack is ejected. The roller 10 is on sliding bearings and moves away from the rollers 11a, 11b against spring action as the pack gets thicker. The blade 5 may be replaced by an eccentric roller or a pair of oneway rollers. The rollers may be replaced by roller segments. In another form, Fig. 3, the roller 10 is replaced by an endless band 17 passing over cylinders 15, 16, the bearings of which can be fixed since the bending of the band allows for the increase in pack thickness.

Title: Improvements in electric time switches
IPC: G04C23/22
Filed: 1931-11-28
Abstract: 373,554. Time switches. HORSTMANN GEAR CO., Ltd. and HORSTMANN, K. J., Newbridge Works, Bath. Nov. 28, 1931, No. 33007. [Class 38 (v).] A time switch has a rocking g switching- member with flexible contact-arms adapted to be partially rotated towards the on position against spring action by a pivoted " make " lever moved by a tappet, whereupon it is held, and the concluding part of the on movement is quickly made as the "make" lever snaps back when clear of the tappet. The rocking contact-member consists of an insulating disc 1 pivoted at 2 and carrying flexible contactarms 4, 6 adapted to co-operate with studs on fixed contact-pins 3, 5 on the base D. A " make " lever 8 pivoted at 10 is held against a stop 15 by a spring 16 which also serves to hold a " break " lever 9 against a latch member 14 to hold the contact-member in the off position. In operation, a pin 21 carried by an "on" tappet F, attached to a 24-hour dial B, engages the "make" hever 8 which in turn engages a pin 18 to rotate the contact-member 1 towards the on position against the action of a spring 17. When the contact - member approaches the on position, an insulated pin 12 on the " make " lever engages the contact-arm 4 to flex it and prevent contact being made'. The disc 1 is however rotated until the catch 14 is held by a detent 19 on the "break" lever, and the arm 6 makes contact. When the " make lever 8 springs clear of the pin 21, it returns due to the action of the spring 16 and the switching action is completed by the flexure of the contact-arm 4. To open the circuit, a pin 22 on the "off" tappet G moves the " break " lever 9 to release the catch 14, allowing the switch to open quickly due to a spring 17 assisted by the flexure of the contactarms. An arm 20 is provided on the lever 9 to co-operate with a pin 23 on the "on" tappet, in advance of the pin 21, to open the switch in the event of its being already "on" when the " on " tappet comes round. Otherwise a slow break would occur. Specifications 329,633 and 331,083, [both in Class 38 (v), Electric switches &c.], are referred to.
