Abstract: 624,787. Batteries. BURGESS BATTERY CO. Jan. 28, 1947, No. 2672. Convention date, April 3, 1946. [Class 53] The zinc electrode 17  of a dry cell is bent up on two sides 21 and along the bottom to enclose the carbon electrode and depolarizer block on four sides. The two electrodes are separated by an absorbent paper sheet 16 which is shaped similarly to the zinc electrode, the paper sheet and zinc electrode being bent together from superimposed blanks of the shape shown in Fig. 4. The lower corners 24 of the paper separator penetrate and close the spaces between the meeting edges of the turned-up sides and bottom of the zinc electrode. The container of each cell consists as shown in plan in Fig. 5 of a sheet 13 of synthetic resin, rubber or other insulating material which is folded round the bottom and two sides of the depolarizer block 14 and zinc electrode 17, the projecting edges 30 of the sheet being cemented together and folded flat against the cell. The contents of the cell are moistened with a solution of ammonium chloride and zinc chloride and the carbon electrode is tipped with solder to facilitate connection with a lug 22 projecting from the zinc electrode of the adjacent cell. Each zinc electrode is provided with a second projection 23 which passes through the sealing composition of the battery as shown in Fig. 1 and is used for testing purposes. The terminals of the battery consist of sockets 26, 27. Specifications 624,786 and 624,788 are referred to.

Abstract: 159,750. Cillario, A. Jan. 30, 1920. Limbs, artificial.- Comprises special means of utilizing the contraction of the muscles of a plastic motor stump to effect the operation of the fingers of an artificial hand. One end of a link 20 engages a hole in the stump in such manner that the contraction of the muscles transmits a pull to the link. The pull is transmitted to an adjustable rod 17, and moves the upper end of it downwards in the slot 19. This movement is transmitted by the tail-piece 16 to the four fingers, which are moved as an integer about the pivot 12 towards the fixed thumb. A spring 25 restores the fingers to the open position when the closing effort is relaxed The hand rotates as a whole on the stump socket 3 through the medium of a plate 23 which is mounted rotatably on the socket between an inwardlyprojecting flange 26 and a securing-ring 25.

Title: Method and apparatus for measuring a time interval
IPC: G04F10/10
Filed: 1968-01-19
Abstract: 1,213,341. Measuring short time intervals. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. Jan. 19, 1968 [Jan. 24, 1967], No.3042/68. Heading G1U. [Also in Division H4] To measure the time interval between a start signal and an end signal, periods of a clock are counted starting from the first period occurring after the start signal up to and including the period comprising the end signal, while the duration between the end signal and the beginning of the first counted period and the duration between the end signal and the end of the period comprising the end signal are each determined by an integrating method in which a subsequentially constant flow e.g. of current is integrated, the duration of integration being that of the required duration plus a constant delay term, the time interval between start and end signals being given by the sum of the time represented by the count and the time represented by the difference between the two integration results. The constant delay term is added to each of the two durations in order to allow time for the establishment of the constant flow which is to be integrated. In an embodiment Fig. 2 clock pulses are provided from a generator 10 and passed to a normally closed gate 11. This is opened by the start signal on line A, to pass pulses via a normally open gate 13 to a counter 14. The start signal also sets a bi-stable circuit 16 which operates a switch permitting current to flow to the integrator 18. The first transmitted clock pulse is also passed via a delay 17 to the other input of the bistable to reset it and cease integration. The end signal on line B operates to close the gate 13 in the path to the counter, and to open the gate 23 so that the next following pulse is passed to the delay 25, preferably the same delay as 17. The signal B also sets the bi-stable 21 which is reset by the pulse from the delay 25 to control the integrator 22. The signals from the output devices 19 and 26 and the count from the counter 14 are combined at 26, the constant terms representing the delays being eliminated to provide the required measure of the interval between A and B. A further system is described (Fig. 4) providing separate count and integrated valve outputs wherein it is shown how the gates are reset after a particular measurement, and how the system is initially adjusted and calibrated.

Abstract: 512,514. Preventing reverse movement of vehicles. BRADSHAW, G. Feb. 1, 1938, No. 3061. [Class 103 (i)] A vehicle transmission system includes a ratchet or like device for preventing reverse movement of the vehicle, interposed between the fixed part and a rotary transmission part, means controlled by the change-speed gear for rendering said device operative or inoperative, and an overload coupling between the said device and the said fixed part and/or the said rotary part. As shown in Fig 1 the device comprises a ratchet wheel 4 formed on the low-gear pinion 1 and a corresponding wheel 5 splined on to a sleeve 6 embracing but not engaging with the shaft 2. The sleeve 6 carries a brake band 7 engaging with a brake lining 8 round a brake drum 9 fixed on to the gear box 10. The brake band is adjustably tensioned by means of a spring 12 and a bolt 13 and nut 14. The ratchet wheels 4 and 5 engage when low gear is engaged, forward running being made possible by the sliding of the wheel 5 on the sleeve 6 against the action of the spring 15. In the form shown in Fig. 2 a ratchet wheel 20 is formed on the casing 18 of a clutch 16 and the co-operating ratchet wheel 21 is carried by a sleeve 22 splined to a sleeve 23 surrounding the shaft 17 and secured to the gear box 24. The plates of the clutch 16 are urged into engagement by the spring 19. In this form the ratchet wheels are brought into operative relation, when low gear is engaged, either by the links 30, 31, and 32 or 36 and 37.
