Patent GB-1258525-A (GB)
IPC: G01R11/36
Filed: 1969-11-28
Abstract: 1,258,525. Electricity meters. LANDIS & GYR A.G. Nov.28, 1969, No.58385/69. Heading G1Q. A phase adjusting device in an induction type electricity meter comprises a short circuiting winding associated with one of the current and voltage coils and a mechanically variable magnetic reluctance, the arrangement being such that the winding is coupled with a fraction of the total drive flux developed by the associated coil, the remaining fraction of the drive flux being branched off and taken past the winding and through the variable reluctance, the value of the remaining fraction and hence of the fraction coupled with the winding being adjustable by varying the magnetic reluctance. The system is particularly for use with a reactive volt-amp meter, in which resistors are associated with the current and voltage coil windings, which in combination with the internal phase adjustment of the driving system ensure that the driving fluxes have a phase difference of 180 degrees when there is phase coincidence between current and voltage. Precise phase adjustment is necessary in such meters. The adjusting device is associated with the voltage coil 2 of such a meter, and incorporates a short circuiting copper ring 10 which surrounds the voltage counterpole 4 and is held in a ferromagnetic holding member 11. A brass shim overlies the holding member over which a pivotable steel yoke 15 is secured. The direct flux path between the central core 3 of the voltage coil and the counterpole passes through a large reluctance air gap 20. Most flux therefore passes via the holding member 11 which is secured to the central core to the counterpole 4 via the limbs 11a 11b. Some flux passes outside the position 21, where the copper ring is secured, via the shim 13, pivotable yoke 15 and again via the shim and holding member to the counterpole. The short circuited ring therefore surrounds most of the flux. By varying the position of the yoke 15, this flux can be varied as more or less flux is enabled to pass outside the ring. Thus the exciting current taken by the coil 2 and the voltage drop across the phase changing resistor in series with it are varied, to produce slight phase adjustment between the voltage applied to the meter and the voltage across the voltage coil.

Abstract: 1320896 Telephone keyset systems POST OFFICE 30 June 1970 [2 July 1969] 33502/69 Heading H4K In communication with a data storage system the ten pushbuttons of a telephone keyset have their normal significance if used singly but have a different significance if used in combination with one or other of auxiliary pushbuttons. The signals produced by the pushbuttons may be characteristic frequencies or frequency combinations or may be D.C. signals. Operation of an auxiliary pushbutton once or a number of times before or after operation of one of the ten pushbuttons will determine the interpretation the computer puts upon the key signal such as to extend the significance of the keys to include letters of the alphabet or operational instructions such as of addition or multiplication. Operation of an auxiliary pushbutton may determine the interpretation to be put upon the ten key signals until further operation of an auxiliary button effects cancellation and reverts the keys to normal numerical significance. The computer is accessed over an exchange system and responds automatically to a call with a ready-to-proceed signal.

Abstract: 1325785 Freeze drying HILLS BROS COFFEE Inc 25 June 1971 29972/71 Heading F4G In a system for continuously freeze-drying liquids or solids containing liquids, material is supplied to an endless belt 12 cooled by spray means 14, 16, 18. The resulting frozen sheet of material is broken up by mechanism 22, the pieces being conveyed by a refrigerated conveyer 26 to a comminuting means 30. This, together with a screening device 32 delivers particles of a desired size to a hopper 34, from where they are delivered, via a second refrigerated conveyer 40 and a vapour lock 48, to a freeze dryer. Freeze drying operation.-A vacuum pump 152 maintains a partial vacuum (100-800 microns) in a freeze drying cylinder 42. A vibrating feeder 52 delivers the frozen pieces to a vibratory conveyer which comprises vertically spaced conveyer decks 54, 56, 58, 60 mounted within a suspended frame by means of flat springs. The frame comprises a conduit through which is passed fluid which cools the conveyer decks from below. Each deck is also heated from above, ice from the frozen pieces subliming on to walls of cooled cryoplate condensers 62. The condensers 62 are periodically heated, the ice falling on to a conveyer 76 which delivers the ice to a breaker 86 and thence melted and disposed of. The conveyer decks each comprise plates fixed at one transverse edge and freely supported at the other on an adjacent plate. When the decks are vibrated at or near their natural frequency the slowly drying pieces move to a hopper 74 and thence via a vapour lock 84 to packageing means. A motor external to the cylinder 42 drives two pairs of eccentrics, 180 degrees out of phase, associated with two rocker arms. Each arm vibrates two of the decks 54, 56, 58, 60 such that the two pairs of decks vibrate in opposed vertical and horizontal relation to one another thereby cancelling out the forces in the frame.

Abstract: 1335201 Semi-conductor device manufacture JOSEPH LUCAS (INDUSTRIES) Ltd 23 April 1971 [21 May 1970] 24550/70 Heading H1K In making a plurality of semi-conductor devices a wafer containing at least one PN junction is mounted on a support and divided into a number of parts by channels in which PN junctions are exposed. The channels are filled with a curable resin, which when cured has an adherence to the semi-conductor stronger than its internal so that on stripping off the resin some remains attached to the parts to protect the junctions. As described the wafer, of silicon, is plated on both faces with metal and attached to a glass or ceramic slide. The channels are then formed in a grid pattern by spraying on wax through a steel mask and etching away the silicon remaining exposed. A silicone elastomer 17 (Fig. 6) in liquid form is poured on to fill the channels and after removal of excess cold cured. Then a layer of rubber 18 which adheres strongly to the cured resin is deposited overall. To separate the diodes tab 19 is gripped and layer 8 ripped off taking with it the resin in the channels. Wax 12 is then dissolved to release the elements from the slide. A recommended curable elastomer is a mixture of alpha-omega dihydroxypolydimethylsiloxane, a polydimethyl siloxane, an acetoxy silane, and a silica filler.
