Title: Automatic frequency control amplifier
IPC: H03J7/10
Filed: 1963-12-06
Abstract: 1,023,742. Automatic frequency control systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 6, 1963 [Dec. 8, 1962], No. 48257/63. Heading H3A. A frequency control voltage is applied over an amplifier to the junction of two series capacitor diodes equally back - biased by a constant voltage from a Zener diode 7 so that the capacities vary in opposite and equal direction but are unaffected by supply voltage variations. A switch 16 connects alternately diode 8 or 7 to a local oscillator circuit and is changed over whenever a frequency range switch alters the local oscillator frequency between values above and below an incoming received frequency. Alternatively the frequency controlled oscillator may be part of a transmitter receiver. The diodes 8, 9 may be in series with resistors 10, 11.

Title: Methods of making ferrite magnets
IPC: H01F41/02
Filed: 1963-12-06
Abstract: 995,375. Magnetic structures. A. W. COCHARDT. Dec. 6, 1963 [Dec. 11, 1962], No. 48315/63. Drawings to Specification. Heading H1H. Anisotropic permanent magnets are made by preparing a green flat body by compacting finely divided particles in a magnetic field (the field being parallel to the compacting pressure and perpendicular to the major surfaces of the body), subdividing the body into a multitude of members, sintering either before or after the subdivision, and magnetizing in the direction of orientation. The magnetic material may be barium, strontium or lead ferrites of magneto plumbite structure. The structure may be partially sintered before cutting. With the invention less power is required in the aligning field per magnet than when magnets are prepared individually, and individual magnets have a higher degree of anisotropy because the magnetizing field will be straighter, except at edges of the structure, and these edge portions may be discarded. Specification 995,374 is referred to.

Title: Process and Device for Connecting a Semiconductor with a Metal Strip by means of a Solder
Inventor: KRAUSE GUNTHER
IPC: H01L21/60
Filed: 1967-10-25
Abstract: 1,173,189. Soldering. ELEKTROMAT VEB. 25 Oct., 1967, No. 48457/67. Heading B3R. [Also in Division H1] A metal strip (not shown) is rested on the active portion 6 of a resistance heating element 7 and has solder deposited thereon from a suction-needle 5. The solder is melted on to the strip by a pulse applied to the heating element and is allowed to solidify. The needle 5 is moved away to pick up a semi-conductor body (not shown) which is placed on the soldercoated strip with the needle resting lightly on the assembly. A brief current pulse is applied to the heating element to bring the assembly to a temperature above the eutectic temperature of the semi-conductor and solder, though below the melting-point of either, and mechanical vibrations are simultaneously applied through the needle from a vibrator (preferably ultrasonic) connected to it. The semi-conductor body is then bonded to the metal strip.

Title: Method of and apparatus for the production of thin films on a substrate or carrier by ion beam sputtering
Inventor: SCHILLER SIEGFRIED
IPC: H01J37/305
Filed: 1965-11-16
Abstract: Thin films e.g. of alloys or compounds are produced on a substrate carrier 1 by sputtering a target 2 by means of an ion beam source wherein the carrier and target are brought consecutively into the ion beam 3.  During sputtering the target, preferably composed of a plurality of different substances for multi-component films, may be moved in a programmed manner relatively to the ion beam axis; or a plurality of targets 5-8 e.g. on a turntable device 4 (see Fig.2), each of a different substance, may be provided with <PICT:1057119/C6-C7/1> <PICT:1057119/C6-C7/2> appropriate masks 9 to prevent contamination of targets and carriers not being subjected to the beam 3.  Preferably, the carrier 1 is first moved parallel to the ion beam from position a into position b and then rocked through 90 DEG  into the ion beam 3 (as shown in Fig.1) to clean it, then restored to position a in reverse sequence, and then the target 2 is moved from resting position c into the ion beam to sputter it, restored to position c and the entire procedure repeated.  The sputtering may be effected under vacuum or a partial pressure of an inert gas.

Title: Process for freezing packaged products

IPC: F25D31/00
Filed: 1962-12-31
Abstract: 950,178. Cooling packages. TEXSTAR CORPORATION. Dec. 31, 1962, No. 49005/62. Heading F4H. In a process for freezing packaged products between vertical hollow plates 11 a first row of packages P is lowered to the bottom of the space between the plates 11 while liquid refrigerant is admitted to the plates to a level corresponding to the height of said first row (Fig. 2) and the packages are partially frozen. A second row of packages is then superposed on the first and the liquid refrigerant level raised correspondingly (Fig. 4), the process being continued until the space between the plates is filled. Frosting of exposed refrigerated surfaces is thereby avoided. The plates 11 are horizontally reciprocable and, once filled, are moved periodically to discharge a bottom row of frozen packages while an unfrozen row is added at the top. The apparatus is unloaded by removing successive rows of packages at the bottom and simultaneously withdrawing liquid refrigerant from the plates to maintain the liquid level at the height of the remaining rows of packages. A vertically movable elevator 15 is provided for raising and lowering the rows of packages.

Abstract: 1,221,690. Controlling reactors. A. REYROLLE & CO. Ltd. 22 Jan., 1970 [22 Oct., 1968], No. 50013/68. Heading G6C. A control rod suspension arrangement comprises an open-link chain 16 attached at its lower end 20 to a control rod 19, and passing up and around a motor-driven driving sprocket 14 and thence hanging down into a chain locker 10 on the floor of which the excess length of chain 16 is deposited. The extreme end 22 of the portion of the chain 16 in the locker 10 is attached to a spring buffer 21 comprising a plunger slidably mounted in guides in a surrounding cylinder and having a powerful compression spring acting downwardly on a head attached to the lower end of the plunger. The spring, which may be pre-compressed, surrounds the plunger in the cylinder and its upper end bears against an abutment shoulder in the top of the cylinder. The surplus chain 16 piles up on the floor of the locker 10 as the control rod is raised and is picked up cleanly from it as the control rod is lowered. Should a rapid emergency insertion of the control rod be required, a clutch (not shown) is released in the motor drive to the sprocket 14 to allow the latter to rotate freely so that the control rod will descend under gravity, pulling the chain 16 over the sprocket 14, until the control rod reaches its fully inserted position, at which stage the part of the chain approaching the sprocket 14 becomes taut and the buffer 21 cushions the shock to the control rod.

Abstract: 1,083,890. Transistor switching circuits. ROBERT BOSCH G.m.b.H. Dec. 18, 1964 [Dec. 19, 1963], No. 51502/64. Heading H3T. [Also in Division F2] In a control for motor vehicle electromagnetic friction clutch, wherein a monostable multivibrator supplies current pulses to the clutch magnetizing winding 42 at a frequency dependent on engine speed the relation between the engine speed and the clutch torque is rendered independent of the air gap by means which reduces the length of the multivibrator pulses in response to the increase in the inductance of the magnetizing winding 42 so as to reduce the main clutch magnetizing current for a certain engine speed. The multivibrator 17, 22 is triggered by primary ignition pulses supplied from contact breaker 2 to the base of the input transistor 17 through a pulse shaping circuit and a capacitor 13. During the unstable state of the multivibrator transistors 22, 32 and 38 are conducting. A differential transformer has three windings: 41, connected in series with the magnetizing winding 42; 37, connected in series with a complex collector impedance of the transistor 32 comprising an inductor 35 and a resistor 36; and 31. The windings 37, 41 are arranged so that at maximum air gap their magnetic fields cancel each other. When the air gap reduces owing to lining wear and the inductance of the winding 42 increases, the RL combination 42, 43, becomes larger than 35, 36 so that a voltage is induced in the winding 31, is rectified by a diode 30 and is smoothed by a network 27, 28, 29. Thus, a negative D.C. control voltage occurs at the capacitor 28 and is applied through a diode 26 to the junction of the capacitor 21 and a resistor 25 to reduce the multivibrator pulse duration with reduction in air gap.
