Title: Milk Cooling and Cold Storage Apparatus
Inventor: MARSHALL FREDERICK GEORGE
IPC: F25D17/02
Filed: 1967-04-03
Abstract: 1,177,952. Refrigerators; cooling liquids. ENGLISH ROSE KITCHENS Ltd. 28 June, 1968 [3 April, 1967; 17 Aug., 1967], Nos. 30833/68 and 37905/67. Heading F4H. A refrigerant evaporator located in the upper part of storage apparatus generates an ice bank which, either directly or indirectly via a heat transfer liquid, cools a roof portion of a storage chamber in the lower part of the apparatus, which chamber houses a bulk milk storage tank which is cooled by, and has its open top closed by, the roof portion. As illustrated, the evaporator 36 maintains water in a tank 35 in the frozen state, thereby cooling water or brine in a tank 37 whose bottom wall 39 forms the roof of the chamber 2 which contains the milk tank 1. The tank is formed from steel sheet supported by a cradle structure 42 and rests on rollers 6. The tank has pivots 11 located between the flanges of an arm 8 which is slidable in mountings 9 and 10 so that the tank may be withdrawn from the chamber and partially inverted, Fig. 7 (not shown). So that the milk tank may be subjected to additional cooling, a circuit is formed by the tank 37, a spray pipe 51 whose sprays 52 are directed against the sides of the tank, a collecting sump 54 and a return pipe and pump (not shown). The return pipe opens into the tank 37 above the brine level therein to prevent blockage in the event of a freeze-up. In other embodiments, Figs. 9-12 (not shown), the additional cooling is provided by an evaporator coil supported on the tank or the chamber. In the former case, the evaporator may have flexible connections to allow for withdrawal of the tank. In the illustrated embodiment a retractable stirrer 68 is driven by a motor 73. In other embodiments, Figs. 15-19 (not shown), the stirrer is not retractable but its shaft includes a coupling at the level of the top of the tank which automatically disengages when the tank is withdrawn. The stirrer shaft may be hollow to allow the passage of a thermometer and to allow filling and emptying of the tank while it is in the chamber. The apparatus may include means for weighing the tank, Figs. 13 and 14 (not shown).

Abstract: 940,264. Removing metal by spark erosion. SONDURE ELECTRIQUE LANGUEPIN. Nov. 13, 1959 [Nov. 14, 1958], No. 38636/59. Heading B3V. A method of spark machining an edge of a workpiece 1 comprises placing the latter in a dielectric bath 10 on a support 2 having substantially free lateral movement and connected to one side of a spark generator, and centring and locating the workpiece by a vertically movable gear 9 including an electrode 6 having a surface progressively fitting the surface to be machined. The support may be mounted on a spring 3 or alternatively on a slender resilient rod, connected to an electrically conductive tank 4 containing the dielectric 10 which may be a mineral oil. An insulated chuck 9 connected to a pair of vertical displacement mechanisms 12, centres the sleeve-like workpiece 1 and the conical head electrode 6 is then lowered to machine and de-burr the inner edge of the sleeve. The spark gap is regulated by mechanism 11 controlled by the gap voltage. In another embodiment, Fig. 1 (not shown), the chuck 9 is connected rigidly to the electrode 6. The electrode and/or the tank may be vibrated during sparking. In another embodiment, Fig. 5, the support 27 is wholly or partly immersed in mercury 28 which conducts current from the tank to the support and permits its lateral movements. The workpiece is a helical spring 26 whose outer edge is machined by an electrode 19 and whose inner edge may be machined by a conical head electrode. If the surface to be machined is elliptical the axis of the conical electrode is inclined to the axis of the workpiece, Fig. 6 (not shown). An insulated replaceable sleeve 36 forms a loose guide for the support 27 and is connected to a vibrator 38 to thereby cause vibrations in the mercury 28 and hence the workpiece 26. Different sizes of sleeves produce different amplitudes of vibration. In a similar embodiment, Fig. 3 (not shown), the electrode is vibrated and the workpiece is guided by a peg projecting upwards from the tank floor; three springs may be machined simultaneously, Fig. 4 (not shown). A continuous process for machining both ends of springs 26, Fig. 8, is performed at a plurality of stations A-H. Each spring is mounted in a tank 4 carried stepwise through the stations on a rotatable table 55. At A the spring is passed into the tank from hopper 44, at B the upper inner edge is machined by electrode 45; at C the upper outer edge is machined by electrode 46; at D and E the spring is inverted by mechanism 47-50; at F and G the other edges are machined and at H the spring is withdrawn by an extractor 53.

[Also in Division F2] A computer 5 employed to control the braking of an aircraft or other vehicle (see Division F2) differentiates signals F, g, derived from inputs C, n and V, divides them at 17 and produces a binary signal Œu according to whether the signs of the original differentials were the same or different, integrates the signal at 19, a value is added at 20 and a signal n c  representing assigned wheel speed produced from unit 21. Signal n c  enters regulator 7 and operates to vary the braking unit 4 to make the wheel speed n reach the value n c . In another embodiment (Fig. 5, not shown), the differentials produce, in units 26, 27, binary signals which are compared by AND gates 29, 30, diodes 28 and relay 31, the output Œu being integrated at 19 and processed as before. In a further modification (Fig. 6, not shown) the binary output from unit 26 is compared, at the units 28, to 31, with the output of the regulator 7. In a modification (Fig. 8, not shown), the undifferentiated value F is passed to a circuit which detects maximum values, the output being processed by a Schmitt trigger device 48, a binary device 49, an integrating device 51, a control unit 52, and an adding device 53 to produce the output n c . In this circuit the signal F is sent on one hand to a detector circuit comprising a diode 44, capacitor 45 and shunting relay 46 and on the other hand to the differential amplifier 47 which also receives the discharge current of capacitor 45 when the latter is discharged by the energization of the relay by the amplifier output.

A device for modulating the pressure of an antiskid braking system by controlling the operation of a solenoid valve 22 is responsive to a continuous input signal from a sensor 18 which is inversely proportional to the angular velocity of a wheel 16 and has a differentiator C 8  receiving the signal to provide a second signal proportional to wheel acceleration and which has a given polarity in the event of wheel deceleration and opposite polarity when the wheel accelerates. The second signal passes to a transistor T 8  the collector of which is connected to that of a further transistor T 9  to the base of which is supplied, by a Zener diode D 6 , a stabilized direct current compensating the base-emitter current of the second transistor for temperature variations so that the transistor T 9  maintains the collector current of transistor T 8  constant. Transistor T 8  provides a third signal transmitted to a flip-flop circuit T 10 , T 11  which operates when the signal passes a threshold voltage to provide two output voltage levels which respectively actuate the solenoid to two operative states for cyclically applying and releasing the brake pressure when the wheel deceleration and acceleration exceed predetermined levels respectively. The device may be provided in duplicate each half receiving a signal from a respective wheel and acting in common upon the brake actuator of the pair of wheels.

Abstract: 954,900. Snap-action switches. E. G. E. JANSSON. Nov. 14, 1960 [Nov. 14, 1959], No. 39056/60. Heading H2B. In a switch of the type comprising fixed contacts bridged by an electrical component, e.g. a fuse, carried by a movable bridge member, arcing between the fixed contacts and component contacts is prevented by mounting the component in contacts on the bridge so that both the bridge contacts and component contacts engage the fixed contacts. As shown, a fuse 7 having knife contacts 8 engaged with and depending from bridge contacts 9 is mounted in a bridge 2. The bridge contacts comprise pairs of U-shaped contacts with diverging limbs the inner limbs 9b receiving contact 8 and the outer limbs 9a co-operating with the outer limbs 3a of a fixed contact 3. The contacts 3 are arranged in pairs and receive the fuse contact 8 between their inner limbs 3b, their inner and outer limbs being biased apart by springs 18. Contact 8 is shorter than contact limb 9a so that in opening it disengages from contact 3 before contact 9a, and in closing engages afterwards. A snap-action mechanism comprises an operating shaft 11 carrying an arm 12 which is in toothed engagement with a similar arm 13. The arms are connected by a tension spring 17 and engage abutments 15, 16 on the bridge. A similar snap-action mechanism is provided at the other end.
