Title: Improvements in or relating to prepayment meters
IPC: G07F15/06
Filed: 1933-07-31
Abstract: 423,438. Prepayment mechanism for meters. WRIGHT, N., 15, Woodheys Drive, Sale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. July 31, 1933, No. 21490. [Class 27] Price-changing mechanism.-In prepayment meter mechanism in which basic charges are collected by a constant speed motor acting in addition to the consumption meter to return the quantity mechanism to zero, the constant speed motor drives through gearing 1, 2, 3, 4 a shaft 5 having fixed thereto an arm 7 carrying a spring-controlled pawl 8. During each revolution of the shaft 5, the pawl 8 engages a pin 9 on an oscillating arm 10 carried by a sleeve 10<a> loose on the shaft 5, the arm being normally held against a fixed stop 16 by a spring 15. The arm 10 is thus carried round with the arm 7 until the pawl 8 meets an adjustable stop 20, which moves the pawl to release the pin 9, the arm 10 being then returned by spring 15. During the forward stroke of the arm 10 a spring-controlled pawl 14 carried thereby drives a ratchet wheel 12 fixed to a sleeve 11 loose on the shaft 5, the sleeve 11 carrying also a pinion 13 which drives a wheel 6 connected to the quantity mechanism differential. The trip pin 20 is mounted on a disc 17 which can be rotated by a central knob 18 to adjust the position of the pin 20 in accordance with the amount of basic charges to be collected in a determined period.

Title: Improvements in or relating to automatic weighing apparatus
IPC: G01G21/00
Filed: 1929-07-13
Abstract: 329,563. Avery, Ltd., W. & T., and Meyer, O. July 13, 1929. Automatic-feed weighers. - An automatic weighing-apparatus of the kind embodying a rotatable multi-compartmented weighing hopper, a power-driven feeding mechanism and an automatically operating clutch device for putting the feeding mechanism into or out of operation is characterized in that the clutch device is actuated by means under the control of trigger arms which determine the operation of the main and dribble feed supply gates governing the supply of material to the weighing hopper. The material from the supply hopper 35 is fed to the upper compartment 6a of the weigh hopper by a bladed feed drum 34 for the main feed and a pug screw 40 for the dribble feed. The weigh hopper sinks until a knife-edge projection 6<d> thereon liberates a trigger 14 and allows the main feed gate to close in the manner described in Specification 284,231. During this movement the shaft 15 of the trigger, operating through linkage 20, Fig. 3, moves a rocker 21 away from a collar 23 connected by a link 26 and lever 27 to a clutch-disengaging plunger 28. The dribble feed is continued through a chamber 41 by the pug screw 40, which carries a sweeper arm 40a and a blade 40<b> to prevent clogging. When the charge is made up, a second knife-edge projection 6e on the weigh hopper liberates a second trigger 13 and allows the dribble gate to close. The movement of the trigger shaft 16 causes a cam 29 to displace a trip lever 30 from the end 24a of a spring-pressed rod, which then rises and brings its upper end, together with the plunger 28, into engagement with spring-pressed clutch members 32, 36, thus disengaging the clutch and stopping the feed drum 34 and pug screw 40. During the above-described operations, a counterweighted lever 42, Fig. 1, resting on a stop 7<a> on the supporting-strap 7 of the weigh hopper has been descending with the weigh hopper. One end of the lever 42 engages a roller 43a on a pendulum lever 43b, which also carries a bent tube 45 containing mercury. During the descent of the weigh hopper the pendulum lever is thus raised and the mercury flows gradually along the tube and prevents too sudden or premature release of the lever 42, which ultimately comes to rest on an eccentric stop 47 out of contact with the stop 7<a>. During discharge, the weigh hopper rises and the mechanism is re-set. To permit a weighing operation to be checked, a hand-operated bolt 52 may be turned so as to prevent the weigh hopper from rotating and discharging.

Abstract: 1,112,293. Wrapping-machines. C. F. TAYLOR (UNITY DESIGNS) Ltd. 26 May, 1965 [26 May, 1964], No. 21749/64. Heading B8C. Articles are wrapped in heat-shrinkable film by forming a curtain of the latter and thrusting each article or group of articles, fed in at right-angles to the direction of thrusting, on to the film, heat-sealing and severing jaws closing behind it, causing the article to be enveloped in a tube. The article may then pass through a heat-shrinking tunnel (not described) to close off the tube ends. Articles, fed in between plates 6, 7 on rollers 5 which may be driven, are each located by a stop (not shown) on a pusher 2. Webs 36 from rolls 12, 13, previously joined to form the curtain, extend in front of welding and cutting jaws 14, 15. The entering article operates a switch causing the pusher to thrust it with the web between the jaws and on to a conveyer 20. After withdrawal of the pusher, the jaws close to sever the package and re-establish the curtain, and the conveyer, operated intermittently by a pneumatic cylinder means 51, removes the package for further treatment. Chains 53, 57, driven also by the means 51, rotate feed rollers 45, 47 to draw off more of the webs. In an alternative web feed, link means (not shown) attached to the pusher drive 21, 23, draws off the web as the pusher moves backwards, loops passing round rollers mounted on these link means being loosened as it pushes the article forward. The machine is fully adjustable for various article sizes.

Patent GB-1041756-A (GB)
Title: Improvements in or relating to mixers
Inventor: SHEPHERD BRIAN OLIVER
Filed: 1964-05-27
Abstract: An annular pan mixer has mixing shovels 16 arranged to pivot on shafts as at 34 having a lug 40 bearing on the end of an adjustable compression spring 56 which has limited lateral movement; the angle between the lug and the spring axis is chosen so that as the shaft turns, the moment arm of the spring force about the shaft axis is reduced.  Thus as the spring force is increased by compression the torque about the shaft remains substantially constant as the shovel 16 rises and falls.  The springs may consist of a stack of disc springs.  The shovels depend from an annular member 8 mounted above the rim of the pan 2 by rollers 6 and rotated by a sprocket chain 20 entrained round it and driven by a hydraulic motor 28.

Title: Magnetic memory element
IPC: H01F10/00
Filed: 1973-05-09
Abstract: 1382977 Magnetic storage devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 9 May 1973 [12 May 1972] 22081/73 Heading H3B A ferrite storage layer 2 mounted on a transparent substrate 1, and intended for use in a magneto-optical store, has its individual storage positions separated by discontinuities in the storage material, and has a non-ferromagnetic surface overlay which exerts a tensile stress on the surface of the storage layer and in its plane. The discontinuities may be provided by grooves 4 extending partially or wholly through the layer or by grain boundaries formed by a sintering process. The layer is prepared by surface grinding and polishing, followed by ion etching to remove cystallographic defects and stresses. A layer 3 of a transparent resin adhesive is used to secure the storage layer to the substrate. The grooves may be produced by conventional photolithographic methods, or by using an energy ray deflected in a controlled manner, preferably by the optical control system used in the magneto-optical store. A further method which produces random discontinuities involves heating the layer so that separations are caused by the different coefficients of thermal expansion of the magnetic layer and the substrate. The grooved layer is overlaid by a vacuum-deposited layer of silica 5 which provides mechanical support, stabilizes the preferred direction of magnetization, and prevents both surface reflection of an incident optical beam and scattering by the groove walls. The magnetic layer may consist of Gd 3 Fe 5 O 12 , and its magnetic state normal to its plane may be changed by the combination of an external bias field of appropriate direction and a light beam of sufficient intensity to raise the temperature of a selected storage portion to the Curie or compensation point. Reading is by the magneto-optical Faraday effect.

Filed: 1951-09-24
Abstract: 710,373. Determining physical qualities of materials. LANTSON, Ltd. Sept. 24, 1951, [Oct. 27, 1950.] No. 22278/51. Class 37. A substance is identified, or the proportions of two substances in a mixture determined, by subjecting a standard volume to electromagnetic waves at radio frequency and determining the resonant frequency or the energy absorption at the resonant frequency. A wave generator 1 Fig. 2 feeds valves 7, 8 whose outputs comprise condensers 22, 23 and radiating inductances 16, 17, coupled to inductances 24, 25, feeding detectors 26, 27 and an instrument 44 or amplifier 4<SP>1</SP>. The substance under test is placed in containers 2, 3 in fixed location .to the radiators 16, 17. It is found that as the frequency of generator 1 is varied the response of the meter shows a minimum at one frequency, the frequency of this minimum depending on the quantity of the substance, and its nature; the depth of this minimum is found to vary with the nature of the substance. Thus, if the quantity is kept constant, a pure substance can be identified by its resonant frequency, and the proportions of a mixture determined either by its resonant frequency or by the depth of the minimum, i.e. its absorption. The containers may have the substance under test following through them. One container alone may be used. The contents of one container may be kept constant.
