[Class 143] In a weighing scale wherein the platter supports extend through a casing enclosing the frame structure, the space between the case opening and the platter support is substantially closed to dust vermin &c. by an adjustable bridging member. As shown in Fig. 2, the platter 40 is supported on an inverted Y-shaped yoke 60 passing between two sections of a computing drum and bearing upon a loop-like lever 62 the fulcrum end 63 of which passes round one frame end member 14' whilst the other end 75 is located at the inner side of the other frame end member 14<SP>2</SP>. The bearings 107, 106 of the computing drum are carried by the members 14<SP>1</SP>, 14<SP>2</SP>. A check link 65 maintains the vertical position of the yoke 60. The end 75 of the lever 62 carries an adjustable nose iron 82, Fig. 5, supported on a bearing block 84 at the centre of an equalizing lever 87. The ends of the equalizing lever are suspended from the weighing springs 93 by means of hooks 90 which engage calibrator bars 92. The lower ends of the springs pass through holes in the calibrator bars so that the effective lengths of the springs may be adjusted. Clips 94 of U-shape secure the calibrator bars to the springs. The computing drum is actuated by a rack and pinion 104, 105, Fig. 5, connected to the bearing block 84 by a shock spring 100, a bimetallic strip 98, a pin 96 and arms 97. The pin 96 extends through an enlarged opening 103 in a U-shaped arm 102 carrying the rack, and prevents excessive movement due to shock. At the customer's side of the machine, an elongated slot through which the weight indications on the computing drum are viewed, is largely covered by a translucent illuminated panel in front of which a frame bearing advertising matter may be slid. Casings.-The casing 16 is secured to the frame structure 15 by dust-excluding attachments 20 and is sealed at its lower edge by a flexible strip 18 carried by a base 10.

IPC: B62D3/12
Filed: 1916-09-11
Abstract: 101,626. Chryst, W. A. Sept. 30, 1915, [Convention date]. Motors, controlling; motors, gearing for- -Internal-combustion engines are started in either direction by (1) an electric motor running always in the same direction and driving through different sets of toothed gearing, (2) a pair of electric motors driving each through independent gearing, or (3) a reversible electric motor driving through a single set of gearing. In the arrangement shown in Fig. 4, the armature shaft 26 of an electric motor 24 is extended to carry a pair of pinions 28, 29, which slide into mesh with a crown-wheel (not shown) on the engine shaft. The pinions are engaged by arms 38, 39 of bell-cranks 90, 91, the other arms of which are in contact with the inclined faces 31, 33 of an actuating-lever 40. To prevent the motor from being driven at an excessive speed when the engine works under its own power, the pinions are constructed as shown in Fig. 5. The part 67 which engages the crownwheel is mounted loosely upon a sleeve 61 and is driven by the end long engagement therewith of teeth 66, having inclined ends, secured to the sleeve. The part 67 is held in engagement with the part 62 by a spring 64, and in the event of overrunning, the noise of the teeth passing one against another serves as an audible signal to the operator. When using a reversible electric motor, a starting-lever engages a pinion with teeth on the fly-wheel and controls the direction of running of the starting-motor by moving different sets of brushes into and out of contact with the commutator on the armature shaft. The brushes are carried in pairs on two pivoted arms, the distance apart of which is regulated by a wedgeshaped member.

Title: Improvements relating to the generation and modulation of electric oscillations
IPC: H03C3/36
Filed: 1931-05-01
Abstract: 379,718. Valve generating and modulating circuits. COMMUNICATION PATENTS, Inc., 60, Broadway, New York, U.S.A. May 1, 1931, No. 12868. Convention date, Oct. 17, 1930. [Classes 39 (i), 40 (iii), and 40 (v).] Electric oscillations are produced by the action of a variable light source on a photoelectric cell, the electric output from which is passed through amplifiers and a delay or phaseshifting device and is fed back to the light source to maintain oscillation. Several adjustable frequencies may be produced, and a further light source energized by signal currents may be used to modulate the oscillations. As shown in Fig. 1 the cell comprises a photo-sensitive electrode 7 mounted in the same envelope as the filament 8, grid 9, and plate 10 of an amplifying valve. Light from sources 57, 58, 59 is focused through a lens 16 and window 17 on the electrode 7 causing voltage variation between it and the filament 8. The electrode 7 is light-sensitive only on its exposed surface, and when it is surrounded by the plate 10, the latter has an opening to admit light. The cathode 7 is directly connected to the grid 9 so that the anode current, is varied, and these variations are passed through delay networks 21, 22, 23 connected in parallel, and thence through amplifiers 24, 25, 26, with tuned output circuits, to the light sources 57, 58, 59. Several frequencies are thus generated simultaneously, each frequency depending on the delay period caused by the network 21, 22, 23 and on the tuning of the circuits 28, 30. Adjustment is preferably effected by ganged control of the elements of the delay network and the tuned circuit. In a modification shown in Fig. 2, a piezo-electric crystal 67 replaces the delay network, and the oscillation generated is modulated by a signal source, such as a microphone 75 or television transmitter 76, connected through an amplifier 77 to a lamp 78, the light from which is focused on the cathode 7.

Unshipping levers.-The change-speed and brake levers and gate are modified so that the levers may be disconnected from the operated parts and moved into an extended slot in the gate to enable the driver to reach his seat without obstruction. The change-speed lever g normally works in the slots b, c, d, e but is shown moved into an inoperative position in engagement with a carrier j moving in a slide i; it is dovetailed into an arm k splined to the selector rod l. The rod l carries an arm m with a pin n which, when the lever g is moved to the left into its operative position passes into a hole o and secures the parts g, k together. In the position shown, the lever g may be moved with the carrier along the slide i, the lever g separating from the arm g, at the dovetailed joint. The arm k is retained in a position for re-engagement by a pair of stops q. The brake lever s works in a slot f and is connected by a pin to a member u, which is telescopically connected to an arm v on the brake shaft w and is provided with a step 4 for the foot of the brake lever s. The member u is provided with a pawl operated by a finger z on the brake lever and engaging teeth on the gate. When the carrier is moved opposite to the brake lever in its " on " position the lever is forced by springs 3 in the member u into the carrier, a pin 5 thereon engaging a hole in the brake lever. The slide is fitted with teeth 2 which are engaged by a pin 1 on the brake lever, and with an extension 10 which normally prevents movement of the brake lever into the carrier. The carrier is retained in its rearmost position by a spring stop 6, and a stop r similar to the usual reverse stop prevents accidental movement of the changespeed lever into the carrier. The device may be applied only to a change-speed lever or brake lever.

Title: Differential sense amplifier circuits
IPC: G11C11/34
Filed: 1976-03-31
Abstract: 1491845 Transistor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 31 March 1976 [21 May 1975] 12972/76 Heading H3T A sense amplifier comprises: a pair of differential inputs coupled to respective input lines 14, 16; a restore circuit Q9, Q10, Q 11 operable to charge the capacitance of one line towards a first potential and discharge the other towards a second potential to make the amplifier insensitive to signals between the inputs smaller than a first voltage; balancing means Q12 operable to reduce the potential difference, between the lines; and means to disable Q12 when the potential difference between the lines falls to a predetermined value. The input to the amplifier is provided by variable threshold FET memory cells S1...Sn which are in a high threshold state when storing a "0" and a low threshold state when storing a "1". Applying a read signal to the gate of any one of these cells will cause it to conduct when storing a "1", but not if it is storing a "0". Standby mode.-An "up" level of the RESTORE signal turns on transistors Q9, Q10, Q11 allowing line 16 to charge towards V REF  and line 14 to discharge towards earth. When the potential difference between the lines is sufficient transistor Q2 turns on and transistors Q1, Q7 turn off giving a low level "0" output at 20. In this condition the circuit is insensitive to small fluctuations in input voltage between lines 14, 16. Balance mode.-The RESTORE signal is switched to its down level, turning off transistors Q9, Q10, Ql I thus disconnecting lines 14, 16 from each and V REF . Since Ql is off, the gate of Q12 can now rise until Q12 turns on shorting lines 14, 16. The potential on line 14 now rises and that on line 16 falls thus increasing the conduction of Q1 until Q12 turns off again. At the same time, the conduction of Q2 is decreased, although remaining sufficient to hold Q7 off. Read mode.-An interrogation signal is applied to one of the cells S1... Sn. If the interrogated cell is in its high threshold state, no conduction results and the circuit remains in the state with Q7 off and a low level "0" output at 20. If it is in its low threshold state, lines 14, 16 are again shorted and the gate potential of Q2 falls below that of Q1 resulting in Q2 turning off and Q1 and Q7 turning on to give a high level "1" output at 20.
