Title: Digital force balance
IPC: G01G7/04
Filed: 1972-12-14
Abstract: 1362770 Digital force balance STANDARD TELEPHONES & CABLES Ltd 14 Dec 1972 57689/72 Heading G4H In a digital force balance, a deflection indicator allows clock pulses to pass to a multistage counter while the balance is out of equilibrium and the output of each counter stage drives a separate digital to analogue converter which converters provide via electromagnets a balance restoring force proportional to the counter reading. As shown balance beam 1 is pivoted at 2 and the load is placed in pan 3. The deflection sensor 6 is a l.v.d.t. and carries a dashpot 10. The l.v.d.t. output is rectified and smoothed at 11 and compared at 12 with a reference voltage 13 which can be varied for tare allowances. When the l.v.d.t. voltage is greater than the reference gate 14 is enabled and pulses from clock 15 are fed to counter 16. The output of each counter stage is fed direct to the corresponding digital to analogue converter 17 and the correct output of these drives the coils of electromagnet 18 providing the restoring force. The windings of electromagnet 18 are such that the maximum current from each digital to analogue converter 17 is about the same. The counter is periodically reset by a slow (0À2 Hz) clock 22. The deflection sensor may also comprise either a shaped vane capacity sensor or a lamp and photosensor. In an alternative embodiment an up/down counter is used and the l.v.d.t. is coupled so that deflections in one direction are positive and in the other negative. Tare correction is provided by an additional winding on the electromagnet 18 operated by a manually adjustable direct current supply.

Liquid is distilled by feeding it through conduit 31 into an apparatus comprising a stationary tray 28 from the periphery of which the liquid is distributed through slots and then flows as a thin film down the internal wall of the cylindrical shell 12 which is heated by jackets 15; the vapours evolved from the film are twice reversed in direction as they pass through stationary de-entraining skirt 44 and then condensed on cooled tubes 47. Condensate is withdrawn from the apparatus through outlet 58; and heavy residue is withdrawn through outlet 54. The apparatus may be evacuated via outlet 27. Skirt 44 comprises two rows of overlapping, polished-metal baffles 43. The temperature of the shell 12 may increase in a downward direction. If desired, a portion of the residue, withdrawn through outlet 54, may be cooled and pumped back to the bottom of the still as quench medium. The still may be used for the distillation of hydrocarbon oils for synthetic alcohols, and for the concentration of fruit juices.

[Also in Division E1] A slate roof or a tile roof of the kind in which the slates or tiles are hung on battens or similar supporting members are strengthened, preserved or repaired by applying to the inside surface of the roof a coating of a plastics material in liquid form, together with a glass fibre reinforcement, allowing or causing the coating to set to form a continuous membrane adhesively secured to the slates or tiles and to the battens or similar supporting members. The plastics material may be a polyester resin. The liquid plastics material may be sprayed onto the inside surface of the roof and simultaneously chopped glass fibre strand blown onto the surface being coated. Alternatively glass fibre reinforcement may be applied in the form of a thin sheet to the inside surface of the slates or tiles and the battens or similar members after a layer of coated material has been applied to them, the sheet or tissue being pressed into place so that it conforms exactly to the shape of the overlapping slates or tiles and the battens or like supporting members. More liquid material can then be applied to impregnate fully and consolidate the sheet or tissue of glass fibre. Strengthening members may be disposed alongside the battens or like supporting members within the membrane. Additional sheets of glass fibre can be added.

Abstract: 1409918 Transistor gating circuits; selector switches TEXAS INSTRUMENTS Inc 22 Dec 1972 [18 Jan 1972] 59333/72 Headings H3T and H4K A multichannel analogue voltage switch has an output transistor common to all channels and connected in series with a first constant current source; each channel includes first and second transistors connected in parallel with each other and in series with a second constant current source to a supply line. A first semi-conductor diode connects an analogue voltage input to the input electrode of the first transistor while a control input is connected to the input electrode of the second transistor. A second semiconductor diode is connected between the junction of the first and second transistors with the second constant current source and the input electrode of the output transistor for decoupling the channel, when not selected, from the output transistor. In operation the second transistor of a channel is responsive to a corresponding control signal input to switch from a conductive to a non-conductive state, thereby switching the corresponding first transistor to a conductive state to transmit an analogue signal to the output via a channel including the first and second diodes the first transistor of that channel and the common output transistor. Each constant current source includes a fixed biased transistor. Signals from input terminals E11, E21, E31, E41 are applied over diodes D11, D21, D31, D41 to the bases of transistors T11, T21, T31, T41 respectively. The emitters of transistors T11, T21, T31, T41 are connected via diodes D12, D22, D32, D42 respectively to the base of an emitter-follower output transistor T1 having the collector to emitter path of a further transistor T2 as its load. The emitters of transistors T11, T21, T31, T41 are supplied over constant current sources comprising the collector to emitter paths of transistors T13, T23, T33, T43 respectively and are connected to earth via the collector to emitter paths of gating transistors T12, T22, T32, T42 respectively: these transistors are normally conductive, that one in the channel tor be used being rendered non-conductive by a gating voltage applied to its base. Transistor T is biased by means of transistor T3 and diodeconnected transistor T4, while the transistors T3, T13, T23, T33, T43 are biased from a network comprising diode-connected transistor T5 and transistor T6. It is shown in the Specification (Fig. 3, not shown) that the signal circuits, e.g. diode D11, transistor T11, diode D12 and transistor T1 are self-compensatory for temperature changes.
