IPC: H01L21/00
Filed: 1965-11-24
Granted: 1966-10-07
Abstract: 1,127,439. Welding by pressure. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Nov., 1965 [26 Nov., 1964], No. 49664/65. Heading B3R. [Also in Division H1J Wire connections between closely spaced electrodes on a semi-conductor body and associated conductors are made by stretching a wire between two relatively movable members, severing the stretched wire at a weakened point, then moving at least one of the members with the severed wire projecting from it to a position where the end of the wire is in register with an electrode and effecting bonding. In a preferred arrangement, Fig. 8, clamp 23, 24 is closed on gold or aluminium wire 22, 5 to 30Á thick drawn from the reel. Relatively slidable members 25, 29 are then moved close together, jaws 9, 10 closed on the tensioned wire and the clamp released. After weakening the wire at a point between the jaws by notching, H.F. heating or sparking the members are moved apart to the limit allowed by stop 31 to break the wire and achieve a preset gap between the broken ends. The entire assembly is then moved a fixed distance beyond the clamp which is then closed and the wire severed at the clamp. The semiconductor device has already been set up under a microscope with two electrodes on the semiconductor body and associated header wires aligned. After moving the assembly to a position where the wire ends overlie the electrodes and header wires a thermo-compression bonding tool is brought up and the wire bonded to the electrodes and header wires in a single operation. The process is then repeated on another device.

Title: Improvements relating to hermetically sealed compressors
Inventor: HAMMOND RICHARD VAVASOUR
IPC: F04B39/12
Filed: 1961-01-02
Abstract: 923,759. Compressors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan 2, 1962 [Jan. 2, 1961], No. 110/61. Class 8(1). Resilient support of an electric motor compressor unit 3, Fig. 3, mounted vertically within an hermetically sealed outer casing 2 is affected firstly by a coil spring 6 extending between the bottom of casing 2 and a recess 8 formed at the bottom of an inner protective casing 9 surrounding the unit 3 and secondly by a pair of torsion springs 7 each connected at one end to an ear 12 of a bracket 11 secured to the outer casing wall and at the other end to a stud at the top of the inner casing 9 whereby the resulting line of action of the torsion springs lies in a plane normal to the vertical axis of the motor 4 and above the lower end of the unit 3. Excessive rotational movement of the unit is prevented by bolts 13 projecting upwardly from casing 9 through apertures 14 in bracket 11. In a modification said movement is prevented by abutment of projections 16, Fig. 2 (not shown), of casing 9 against lugs 17 secured to the side of casing 2.

Abstract: 462,862. Exchange systems. SIEMENS BROS. & CO., Ltd., CRUTCH, L. S., and CHITTENDEN, P. A. Jan. 2, 1936, No. 134. [Class 40 (iv)] [Also in Group XL] In a voice-frequency signal receiver employing a current limiting valve and having means for disabling the receiving valve upon receipt of a selected submultiple of the signalling frequency, the tuned circuits fed by the limiting valve are all coupled through rectifiers to the grid circuit of the receiving valve. As shown, the limiting triode VA feeds the primary windings of three transformers TRB and TRC bemg tuned to the signalling frequencies (600 and 750) and TRD to a frequency midway between the sub-multiples of the signalling frequencies (e.g. 340). Alternatively, both windings of the transformer TRD may be tuned to resonate at the two submultiple frequencies (300 and 375). The secondary windings of the transformers are connected through rectifiers RB, RC, RD of the voltage-doubling type to the control grids of the receiving pentodes VB, VC, the rectifier RD being arranged to control both grids in opposition to the rectifiers RB, RC. The negative bias for the control grids is obtained by connecting the cathodes to a tapping on a resistance YD shunted by a ballast resistance BRA and by connecting one terminal of the rectifier RD to negative battery. Specifications 354,250 ; and 405,436, [Group XXXVII], are referred to.

Title: Improvements in or relating to the manufacture of sponge rubber
Filed: 1951-01-11
Abstract: Sponge rubber is obtained by bringing a foamed latex of natural or synthetic rubber into contact with a moulding surface which has been treated with glycerin, lanolin, or urea, setting the foamed latex and then curing.  The moulding may be effected in individual moulds in which case lanolin or glycerin is preferably used, or the foamed latex may be poured onto a continuous metal belt which has a very thin deposit of plate-like crystals of urea, on entering boiling water at the start of the cure the gelled foam strips off the belt instantly.  The lanolin may be applied in solution in carbon tetrachloride optionally with additional gasoline, and the urea and glycerin in alcohol.  In an example, the foamed latex is made by mixing natural rubber latex, sulphur, piperidinium pentamethylene dithiocarbamate, mercaptobenzothiazole, sym. di-beta naphthyl paraphenylenediamine and water and then whipping in a mixture of aluminium sulphate and zinc oxide.

Title: Constant speed controller of dc motor

IPC: H02P7/288
Filed: 1983-01-05
Abstract: PURPOSE:To reduce the phase delay in a control loop by comparing an angular velocity signal of the amplitude in response to the angular velocity component of a sinusoidal wave AC signal proportional to the rotating speed of a motor with a reference angular velocity signal, thereby controlling the motor. CONSTITUTION:The absolute values of sin omegat and cos omegat are detected by absolute value detectors 31, 33 and a differentiator 32 from the sinusoidal wave AC signal of an AC generator 2 provided in a motor 1, set to signals representing the angles via tan<-1> circuit 34, further set to a signal representing the angular velocity by a differentiator 35, and inputted to a comparator 7 through an absolute value detector 36. It is then compared with the reference angle velocity signal of a reference voltage generator 8, and the motor 1 is controlled through a drive circuit 11. Accordingly, since it is not necessary to provide an integrator in the closed loop of control, the phase delay can be extremely reduced, a loop gain is increased, and the irregular rotation can be reduced.
