Title: Engine starting device
IPC: F02N3/04
Filed: 1920-02-24
Abstract: 139,482. Knopp, J. W. Feb. 24, 1919, [Convention date]. Turning-gear. - A motorvehicle engine is started by means of a pedal 18 connected to one arm 7<a> of a bell-crank lever 7, the other arm being connected by a chain &c. 9 passing over a pulley 23 to a segment 25 on an arm 26, which is loose on the engine shaft 4 and turns the shaft by means of a pawl 27 engaging an internally-toothed ratchet wheel 29. The lever 7 and pulley 23 are carried by a bracket 5 secured to the engine top by screws 6, which may also secure the engine cap in the case of a Ford engine. The shaft 10 of the pedal passes through a sleeve 11 swivelled on the lever arm 7a, and has studs 14, 15 normally situated one at each end of the sleeve 11 and coupling the shaft 10 to the sleeve. This coupling can be disengaged by turning the pedal 18 until the stud 15 registers with a longitudinal groove 17, Fig. 6, in the sleeve 11, so that the shaft 10 can slide through the sleeve until a slot 22 in the pedal plate passes over a loop 21 on the dash and a padlock can be applied. The shaft 10 may pass through either of two apertures 20 in the dash-plate 19, and the sleeve 11 may engage either of two apertures 13 in the lever arm 7<a>.

Title: Improvements in the construction and operation of precision balances
Inventor: WHITCROFT ROBERT JOHN
IPC: G01G7/06
Filed: 1953-02-27
Abstract: 771,593. Correspondence control systems for weighing. STANTON INSTRUMENTS, Ltd. March 1, 1954 [Feb. 27, 1953], No. 5592/53. Class 40 (1). [Also in Group XVIII] A balance for continuous or continuously recorded weighing comprises mechanism for step-by-step application or removal of weights controlled when the balance beam approaches either of the limiting positions of its range of deflection by a sensing device which does not impose any restraint upon the movements of the beam. Balance beam 2, Fig. 1, carries a condenser plate 1, so that movement of the beam produces a corresponding variation of capacitance 1, 3 to produce a signal from 5 to control a servomotor 4 which moves condenser plate 3 to restore the capacitance to its original value; the servomotor 4 also actuates an indicator 8 which at its limits of movement operates switches 6 to actuate mechanism 7 for adding or subtracting weights on the beam 2. When switch 41, Fig. 5, is in its left-hand position, the closure of e.g. contacts 6a by the recording indicator 8 energizes relay 45 to close contacts 45a and start motor 22 to drive cams 16 which actuate hooked levers to successively add or subtract-weights on the beam; motor 22 also actuates cam 28 which holds switch 30 closed when cams 16 are in an intermediate position so that relay 45 is held actuated over its contact 45b irrespective of whether contact 6a is open or closed; when contact 6a opens, motor 22 runs until contact 30 opens so that no cam 17 is in an intermediate position. If contacts 6b are closed, motor 24 is similarly actuated to operate weight-adjusting cams 17. When switch 41 is in its right-hand position, motor 22 or 24 is energized over contacts 29 or 23, so that the motor runs through its range to its home position when cams 27 or 31 operate to open contacts 29 or 23 to stop the motor. The cams 16, 17 may operate to add or subtract weights on one side of the beam, or on both sides of the beam. The motors may be replaced by a reversible motor.

Abstract: 1,087,102. Photo-electric thickness measurement. EMHART CORPORATION. Feb. 9, 1966 [Feb. 25, 1965], No. 5646/66. Heading G1A. [Also in Division G2] The thickness of a coating upon a glass or plastics article or a crystal which thickness is of the order of the wavelength of light, is measured by determining the intensity of a beam reflected off the coating when the article or crystal is immersed in a liquid having the same refractive index as the base material of the article or crystal. In Fig. 2 a glass bottle 26 is partially immersed in and partially full of xylene or monochlorobenzene 32 and is held in position by a spring biased lever 44, 56, which is deflected downwards as the bottle is inserted into the reservoir 30 of the liquid and which then urges the bottle against two vertical posts 46 and 48. The base of the bottle rests upon a platform 50 whose height can be adjusted and which, together with the posts 46 and 48 and the lever 44, 56, is carried by a lid of the reservoir having an aperture through which the bottle passes. A variable-positionable light source 78 directs a beam through the liquid on to the coating on the bottle and the reflected beam is received by a selenium photo-cell 94 mounted upon a hinged support 96, 98. In setting up the apparatus the reservoir is rotated to align an indexing-rectangle, inscribed upon the reservoir, with the photo-cell. After which the photo-cell is swung away, Fig. 4 (not shown), and the position of the light source adjusted so that the reflected beam, which fans out due to the curvature of the bottle, is centred upon the rectangle. The indexing rectangle is then moved aside and the photo-cell swung back into place. A partition 42 shields the photo-cell from direct light from the source. A meter 114 is provided. An article, such as a flat plate may be held in a vertical position against the ports 46 and 48 by the spring-biased lever 44, 56, Fig. 5 (not shown).

Title: Multiplex telephone system having reduced band-width
IPC: H04B14/02
Filed: 1949-03-04
Abstract: 663,397. Telephone transmission systems. STANDARD TELEPHONES & CABLES, Ltd. March 4, 1949 [March 5, 1948], No. 5933/49. Class 40 (iv). A distributer 2, Fig. 2, cyclically connects n lines 1, 1, 1 to the transmission channel 3, and a further distributer 4 cyclically connects the channel 3 to n receivers 5, each receiver being fed through a network comprising (n-1) delay devices 6, 7 shunted by one-way conductors 8, 9 so that the signal is repeated n times to be substantially continuous. In a modification, a single delay device 14, Fig. 5, is used, and is shunted by a gating circuit 16 and an amplifier 15; the gate 16 is controlled by the distributer to be closed while the receiver is connected to the channel 3 so that when the receiver is disconnected the gate is open and the signal is repeated continuously. The three lines 1, Fig. 2, may be the output lines of apparatus which is fed with m signals, and shifts the frequencies of each of the signals so as to give a wide band in which the individual signals occupy adjacent frequency ranges, Fig. 4 (not shown). In Fig. 6, signals in lines 1 are all shifted in frequency, e.g. to occupy the range 4600 c/s. to 7700 c/s., and are " chopped " by a distributer 18; the pulses of variable amplitude so produced are translated into a five-unit code, and applied with other similar signals to the input of a distributer 19; at the receiver, a distributer 21 feeds the appropriate channels 2, where the five-unit code is transformed back into varying amplitude pulses by circuit 22, these pulses being repeated by circuit 23 (as in Figs. 1 or 5) and applied to distributer 24 for demodulation at 25. In a further modification, Fig. 7, the output from each distributer 27 is stored on the screen of an iconoscope 28, each row thereon comprising one pulse from each of the channels 1 ; by scanning these rows vertically, all the signals from each channel are sent consecutively so that the pulse from one channel only occasionally is adjacent to a pulse from another channel, thus reducing cross-talk. At the receiver, similar iconoscopes 32 operate in reverse to distribute the signals to the appropriate channels.
