Filed: 1970-12-17
Abstract: 1282800 Antiskid braking systems FIAT SpA 17 Dec 1970 [31 Dec 1969 11 Dec 1970] 59987/70 Heading F2F An antiskid braking system has a solenoid valve 26 controlling hydraulic fluid flow from a pump 10 to a reservoir 14 to control the pressure applied to a wheel cylinder 20 and being driven by a pedal operated potentiometer 34 the solenoid 28 being operable through an antiskid signal fed from a tachogenerator 54 denoting incipient wheel lock to exhaust the pump delivery to the reservoir 14 when the wheel deceleration exceeds a predetermined limit. In the embodiment shown the solenoid valve 26 comprises a valve member 88 which opens an inlet 96 to an outlet passage 86, the communication between these passages being progressively closed during normal braking to allow fluid to pressurise wheel cylinder 20 as the potentiometer output varies with pedal travel. The potentiometer is fed with a constant voltage supply 35 and its output passes via preamplifier 36, capacitor 38 and conductor 42 to a junction 43. When wheel-lock is detected the tachogenerator signal passes by way of capacitor 56, parallel resistor 58, conductor 60, Schmitt trigger 62 and conductor 64 to an NPN transistor 52 and then to junction 43. A voltage source 53 is then caused to pass a voltage to the junction 43 and then to a power amplifier 46 which delivers maximum power to the solenoid 26 allowing the valve to relieve braking pressure. In another embodiment, Fig. 3 (not shown), the normally closed valve 26 is replaced by a normally open solenoid valve (126), transistor (152) is of the PNP type and the sliding contact (132) is biased in its rest position to the low voltage end of the potentiometer 34.

Abstract: 648,394. Applying closures to bottles &c. ANCHOR HOCKING GLASS CORPORATION. Sept. 19, 1947, No. 25610. Convention date, Oct. 11, 1946. [Class 125(ii)] A sealing machine for applying screw type closures to moving bottles &c. in vacuo includes a rotatable turret with a plurality of sealing heads thereon movable in registry with said moving containers, each sealing head having an individual lowerable hood for forming a chamber from which air is to be withdrawn, a chuck within each hood for screwing a closure onto a container, and means for rotating the chucks. The machine shown is similar to that described in Specification 607,703, but is adapted for applying screw caps. Caps are supplied to star wheel 10 from a hopper 16, the cap feed being controlled by a release pin 171 operated through levers 174, 177 by an arm 180 deflected by each passing container 6. A cap is picked up from star wheel 10 by magnets in the cap holder 95 of a passing sealing head 15, Fig. 4, the hood 76 being at this stage raised above the level of holder 95 by engagement of a roller 55 with a raised portion of a stationary cam 24. The sealing head with cap moves into register with a container, at which time cam 24 falls to drops hood 76 about the upper end of the container, engagement of a member 91 with the container moving a valve pin 85 to put a vacuum conduit 75 in communication with hood 76 via a screen 80. The other end of conduit 75 communicates with a moving valve member and is now brought into register with a stationary arcuate vacuum port containing an arcuate bar adjustable to vary the effective size of the opening to conduit 75 so that the container is subjected to a slowly increasing vacuum which will not disturb the container contents; alternatively, the valve may be arranged to apply the vacuum gradually by bringing conduit 75 into communication with an increasing number of vacuum grooves in the stationary valve member. During evacuation, the cap is held spaced from the container mouth by member 95. When evacuation is complete a roller 69 engages a stationary cam to lower the cap onto the container; member 95 then yields against a spring 100 and a rotating chuck 96 continues to descend to engage the cap and screw it home on the container. Chuck 96 is driven through a friction clutch 22a, 120a which is adjusted to slip when the cap is screwed on to the proper tightness. Cam 24 now raises the head 15 and the container moves away to the delivery end of the machine. In a modified form of sealing head, the vacuum port in hood 76 is not screened but the cap is held in contact with the container mouth during evacuation. Instead of evacuating air through conduit 75, steam may be injected therethrough, the gasket 78 which engages the container neck being in this case unnecessary. A filling machine may be combined with the sealing machine and driven as a unit therewith.

Abstract: 656,601. Calculating-apparatus. HERZSTARK, C. Dec. 31, 1947, No. 35027. Convention date, April 12, 1939. [Class 106 (i)] A compact calculatng machine with a single stepped-toothed drum and transfer and totalizing elements arranged in a circle round it, is characterised in that the entering wheels and tens transfer wheels are provided with less than ten teeth, preferably five, and a reduction drive is provided between the entering wheels and the number wheels so that the number wheels make a tenth of a revolution for each tooth of the stepped drum. Pinions 4 are slidably adjusted by arms 6, justified by spring-pressed balls 9 in notches 8, so that their positions on their respective splined shafts 5 vary in accordance with the digits in a number being set up and correspond to the number of teeth on a stepped drum 3, around which the shafts are arranged, with which the pinions will engage when the drum is rotated by a cranked handle 2, pin-wheels 10 on the shafts 5 then engaging pinions 11, justified by spring-pressed balls c and rigid with decade cams 12 and numeral drums 13 which are rotatable on pins 14 inserted in radial slots in a rotatably journalled body 16. When a numeral drum 13 passes from 9 to 0, its cam 12 depresses a spindle 20<SP>1</SP>, justified by a spring in grooves 29, and lowers a pinion 18, on the shaft 5 corresponding to the next higher denomination, into the path of a tooth 22 on a plate 24, rotatable on the shaft 1 of the drum 3 by which it is driven through pin and slot 27, and subsequently as the turn of the handle 2 is completed, the pinion 18 is advanced one tooth and a sloping lug 25 lifts the pinion 18 and spindle 20<SP>1</SP> free from the path of the tooth 22 to a position where a pinion 17 is locked against rotation by a plate 26. To spread the driving and transfer operations over as much of a complete turn of the handle 2 as possible, reduction gearing is introduced as, for example, by forming the pinions 11 each with ten teeth and the pin wheels 10 and pinions 4 each with five teeth. For strength the teeth of the drum and of the entering and transfer pinions are formed asymmetrically and resemble ratchet teeth, the drum rotating in one direction only.

Abstract: 731,761. Moving-coil electrical indicating instruments. RECORD ELECTRICAL CO., Ltd. May 25, 1954 [May 26, 1953], No. 14607/53. Class 37. The flux collecting piece b has a locating face so as to accurately position the central pole iron c. In the assembly process solder foil is placed between permanent magnet a and collecting piece b, between permanent magnet a and return iron f and between return iron f and yoke e. The central pole iron c is located by a spring-loaded screw (temporarily in place of non- magnetic screw g) and a gauge of the air gap size required is placed around the central pole iron c. The complete assembly is then heated to solder the parts together and afterwards the spring loaded screw is removed and the central iron c withdrawn for the purpose of removing the gauge and inserting in position the moving coil d through radial gap k. The central pole iron c is now replaced with exact locational accuracy due to the V-shape on the collecting piece band is secured by non- magnetic screw g. The angle of the V is so proportioned to the angle of the thread on the securing screw g that there is no tendency to either open or close the radial gap k when tightening the screw g. The parts of the assembly may be secured together by adhesive instead of solder.
