Patent GB-1303005-A (GB)
IPC: H02P7/295
Filed: 1971-04-16
Abstract: 1303005 Control of DC motors STANDARD TELEPHONES & CABLES Ltd 16 April 1971 9584/71 Heading H2J [Also in Divisions G3 and H3] A motor control system in which a series motor is controlled by varying the firing angle of a thyristor 3a comprises an A.C. power supply 13, 24, a motor circuit 1, a thyristor circuit 3, a firing signal generator 4, and a control circuit 5 associated with the outputs from a tachogenerator 8 and a motor current sensor resistor 61 incorporated in a protection circuit 6. The firing circuit 4 is based on the charging of a capacitor 22 via the resistors 30, 19 on positive half cycles, the resistor-capacitor connection being attached to a terminal of a silicon controlled switch 20 of the thyristor type such that when the voltage across the capacitor exceeds that at the terminal of switch 20 which is connected to the control circuit 5 via a transistor 39, the switch 20 closes discharging the capacitor through the gate circuit of the thyristor, thereby supplying a motor current for the remaining period of the positive half-cycle (Fig. 2, not shown). The time after the beginning of the cycle at which the thyristor triggers depends on the size of the control voltage supplied to the switch 20 by the control circuit, i.e. on the base voltage of transistor 39. When the power is switched on the capacitors 51, 52 are uncharged and transistor 39 is unconducting thereby yielding a high control voltage to which capacitor 22 must charge for firing to occur and firing accurs towards the end of the positive cycle. As the capacitors 51, 52 charge up the control voltage drops, the thyristor fires earlier in the cycle and the motor speeds up until the charging of capacitors 51, 52 is counterbalanced by the rectified output of the A.C. tachogenerator 8 at which stage the motor speed stabilizes. A D.C. tachogenerator may be employed if the circuit is modified suitably. The potentiometer 42 can be used to vary the speed setting. Should an increase in the motor load cause it to slow an increased current flows through resistor 61 and this increase in voltage is detected by the control unit input resulting in the control level on the switch 20 being lowered increasing the power supplied to the motor. If the current through resistor 61 rises above a prescribed limit, the transistor 65 in the protection circuit 6 conducts thereby causing the rate of charge of capacitor 22 to be lowered. As the current increase also leads to a decrease in control level, there comes a time when the charge delivered by capacitor 22 to the thyristor gate is insufficient to cause the thyristor to trigger and hence the current is limited. In a washing machine, the switches 70, 71, 58, 59, are used to select either one of two washing speeds or a spinning mode in which the motor is operated at its maximum speed.

Title: Preparation of films
IPC: D04H1/60
Filed: 1970-08-13
Abstract: 1327586 Preparation of films SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 9 July 1971 [13 Aug 1970] 38990/70 Heading B5B [Also in Division C3] Films are made by electrostatically depositing particles of thermoplastic macromolecular material on to an earthed endless moving surface, heating the particles until they fuse together and then removing the layer before or after cooling it. The particles may be solid or liquid and may be applied from a spray-gun or, if solid, from a fluidized bed. Preferably the particles are charged. The surface is made of an electrically conducting material and is either a belt or a drum; it has a melting point higher than that of the thermoplastic material. Additives such as quartz, talc, clay &c. or pigments may be incorporated into the particles or they may be on the surface before deposition occurs. Fibres having a melting point above that of the thermoplastic material can also be incorporated into the film, preferably by depositing first a layer of particles, then a layer of fibres and another layer of fibres and fusing them and passing through one or more sets of pressure rollers. Examples illustrate the production of films of polyethylene, polypropylene and polyvinylchloride alone and mixed and with or without additives such as china clay, titanium dioxide, calcium carbonate and quartz. Whilst the film is still fused, a layer such as a knitted cotton fabric may be pressed on to it to give a laminate.

Abstract: 1332601 Anionic polymerization of lactams LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT 10 Feb 1971 4380/71 Headings C3R and C3C The anionic polymerization of lactams having at least 6 ring members employing alkaline catalysts and activators is effected in the presence of a heat stabilizing additive wherein the R groups are independently alkyl or aryl or a pair thereof form a ring and M is Cu, Ni, Mn, Co, Cd, Zn and Fe. It is stated that because of the absence of labile hydrogen the compounds do not interfere with the catalyst and even accelerate the polymerization. The process is applicable both to solid castings and foams. Other additives which may also be present are dyes; lubricants e.g. graphite or MoS 2 ; crystallization regulators e.g. active soot or BaSO 4 ; and polyamide waste. In examples the lactam is capro-, enantho- or a mixture of capro- and lauro-lactams; the catalyst is metallic sodium; the activator is dicyclohexyl-carbodiimide or N-acetyl-caprolactarn; and the heat stabilizer is that wherein the R groups are butyl, methyl, dodecyl, phenyl or pentamethylene. In Ex. 2 active soot is also included and in Ex. 5, wherein a foam is obtained, 3,4,5,-trimethoxy benzoic acid azide is used.

Title: Electrical circuit for dc excited magnetic systems
IPC: H01F7/18
Filed: 1971-07-21
Abstract: 1337314 Transistor switching circuits KOMBINAT ELEKTROMASCHINENBAU VEB 21 July 1971 34211/71 Heading H3T [Also in Division F2] A spring operated clutch or brake is released by an initial operating current in coil 1 which is at least 20 times the subsequent holding current in coils 1 and 2, the mean level of the initial current being increased by a "freewheeling" circuit D3 in parallel with coil 1, the resistance of D3 being lower than the coil 1 resistance under initial current conditions, and higher than it under hold current conditions. D3 is forward biased by the back e.m.f generated across coil 1 when each half cycle of current through the coil falls, and thus maintains a current in the same direction in the coil during the following negative half cycle. The induced e.m.f. and the diode voltage-current characteristic are selected to produce the higher resistance for D3 under hold current conditions in order to dissipate more rapidly the current when the coils are switched off. The hold current half cycles are supplied by D17 and the initial current half cycles by thyristor 6. Upon switch-on, D11 charges C13 during the first pulse of A.C. until a trigger diode 7 conducts due to a Zener 9 being biased on, and SCR 6 conducts to energize coil 1. During the next pulse through D11, the voltage across R15 takes longer to reach the Zener breakdown level since C13 is already partly charged, and so SCR6 conduction is made progressively later in each successive rectified A.C. pulse, until it stops conducting, and just the hold current from D17 flows. R16 is voltage dependent to make the number of pulses produced by SCR6 independent of the supply voltage level. D3 is a selenium diode and may be replaced by a Zener and silicon diode, or a voltage-dependent resistor and a silicon diode. The brakes or clutches are for use on elevating and conveying devices, and in machine tools and processing machines. The electromagnet system has two pot shaped cores with a variable air gap.

Abstract: 1355651 Flexible-tube fluid-driven motors D R TAYLOR 23 June 1971 [2 April 1970] 15555/70 Heading F1F An inflatable flexible tubular-envelope 1 is stored in a flattened condition on a rotatable drum 6 and furnished with tubes 2 through which working fluid e.g. compressed air or a pressurized liquid, can enter its free end from a supply duct in the drum. The tubes pass on either side of freely-rotating rollers 4, which serve as an abutment. Inflation of the envelope renders the free portion relatively rigid, produces linear thrust and unwinds the remainder of the envelope from the drum. The tubes 2 are accommodated in annular grooves in the drum, Fig. 5 (not shown). The envelope may comprise longitudinally extending compartments, Figs. 6 and 7 (not shown), and a series of rollers may replace the rollers 4, Fig. 8 (not shown). A single tube may replace the tubes 2, the rollers 4 then being modified to accommodate this tube, Figs.9 and 10 (not shown). To retard the envelope at the end of its outward stroke from the drum 6 vents may be provided in the envelope so that fluid can escape therefrom and produce counter forces due to reaction, Fig. 11 (not shown). Alternatively, either the last of the flattened portion of the envelope to pass between the rollers is tapered so as to form a wedge, Fig.12 (not shown), or the inertia of the drum provides a braking action, Fig. 13 (not shown).

Title: Methods for the characterization of compounds which stimulate somatostatin transactivating factor 1 (stf-1) expression in pancreatic islet cells
Inventor: MONTMINY MARC R
IPC: C12Q1/6897
Filed: 1998-06-30
Abstract: One embodiment of the present invention provides a method of testing for compounds which may induce STF-1 transcription. Pancreatic islet cells which express the STF-1/lacz fusion gene are isolated and the effect of various compounds on STF-1 expression is measured by adding the compound of interest to STF-1/lacZ expressing cells. LacZ activity in control and treated cells is then quantitated by a colorimetric assay. Using this method, a large number of compounds can be screened and STF-1 inducing compounds can be identified readily. Another embodiment of the present invention provides a method of using the STF-1 promoter to mark insulin producing pancreatic islet cells in vivo. In this regard, the green fluorescent protein (GFP) served as an indicator. The introduction of the STF-1 green fluorescent protein transgene into pigs allows for the efficient and rapid recovery of insulin producing cells from the pancreas.
