Abstract: 1,211,017. Metallizing plastics by electroplating. ROHM & HAAS CO. 13 Oct., 1967 [24 Oct., 1966], No. 46825/66. Heading B2E. [Also in Division C7] A plastics substrate is metallized by applying thereto a primer comprising a graft or layer copolymer comprising by weight 15- 75% of butadiene/styrene polymer having grafted or layered thereon 85-25% of the polymer one or more monomers, and then electroplating the primed substrate, e.g. with Cu, Ni, Zn, Cd, Cr, Au or brass.

Title: Signal Generator
IPC: H02P1/30
Filed: 1967-10-16
Abstract: 1,154,788. Control of A.C. motors. GOLAY BUCHEL & CIE S.A. 16 Oct., 1967 [14 Oct., 1966], No. 46963/67. Heading H2J. The commutation of an induction motor is controlled by signals representing the speed of the motor and the slip, the speed-responsive signal being derived from an apertured disc which is driven by the motor and co-operates with a photo-electric device, for example, and delivers a set number of pulses per revolution of the motor. In one arrangement, the signals representing the speed and slip respectively are added to form a signal which is applied to a frequency divider for controlling the rate of commutation. In a modification, the commutation-signal is subtracted from the speed-signal to form the slip-signal which, in turn, modifies the commutation signal. A circuit for subtracting the commutationsignal, applied to input 2, from the speedsignal, applied to input 1, comprises a bi-stable flip-flop formed by transistors 10, 11. If two successive pulses are applied to input 2 without an intervening pulse on input 1, transistor 11 is conductive at the same time as the transistor 16 and a subtraction pulse is delivered over line 18. A transistor 19 becomes conductive when it receives the pulses over line 18, and if the frequency of these pulses is sufficient, diode 20 conducts to reduce the potential on line 32. This potential sets the frequency of oscillation of a multi-vibrator comprising transistors 21, 22, for determining the commutation frequency. When the motor is started, the potential on line 32 is increased at a rate determined by resistor 24 and capacitor 25 to increase the commutation frequency until the limit set by potentiometer 35 and transistor 23 is reached. If an overload causes excessive slip, the transistor 19 responds automatically to reduce the commutation frequency in a manner to maintain maximum torque.

Title: Data handling switch and apparatus

Abstract: 1527914 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 26 Nov 1975 [7 March 1975] 48505/75 Heading H3B [Also in Division G4] A switch for manipulating two streams of data A, B, (Fig. 2) permits the two streams to either cross each other without destructive interference so that the data may exit at outputs C, D respectively or by-pass each other so that the data exits at outputs D, C respectively. As described switching of this type connects shift registers arranged in a ladder formation L1-L4 (Fig. 3). Both switches and registers may comprise charge coupled devices or as described magnetic bubble domain devices. Connectors 14A, 14B have portions of reduced width where intensified magnetic field gradients are produced to direct the bubble streams to achieve by-pass operation. With no current in conductors 14A, 14B the input streams A, B cross each other at different phases of drive field H and continually move during all phases of H. With a current conductor 14B during field phases 4, 1 the bubble domain at position b will transfer to position 4<SP>1</SP> of element 18 and after the next field phase 2 it will move to pole position 3 of bar 19 and hence exit at output C. Similarly with a current in conductor 14A at field phase 1, the bubble domain of position a is directed along element 20 to position d and hence exits at output D. Ladder operations.-By connecting all the switches in cross over mode, after they have been connected in by-pass (idling) mode for an even or odd number of cycles the stored data is ready for read out in a first in/first out or last in/first out basis respectively. Data may also be stored so that most recently used information is nearest the I/O loop by fetching a requested item to the I/O position and pushing all intervening items down one position. To access for example item E (Fig. 7A-7G, not shown) the ladder shift registers are first connected in cross over mode and shifted for three cycles until the item E is in the first register (Fig. 7B, not shown) of the ladder (i.e. ladder Ll, Fig. 3). The contents of half ladder L1 and the I/O ladder are then exchanged with the other ladders idling for one cycle (Fig. 7C, 7D, not shown) with the I/O ladder idling the other ladders are cross connected and shifted for three cycles (Fig. 7E, not shown) and then all except the I/O ladder are idled for one cycle (Fig. 7F, not shown). This method of removing an item from its position in the ladder arrangement may be used for text editing.

A hermetically sealed food package comprises an open mouthed food-containing portion, with a pleated rim sealed to the smooth unpleated rim of a rigid panel-type closure carrying a wax gasket. The material of the gasket consists of a wax base substance having a uniformly dispersed oil content ranging from about 15% to 50% by weight and when the closure is applied to the container the oil is exuded from the wax and runs into the pleats of the container rim to effect a hermetic seal between the closure and the container. As shown in Fig. 8, a container 33 comprises an open-mouthed plastic bag 40 housed within a rigid wall 34 and supported upon a metal base 35 attached to the wall by conventional means. The bag is pleated at its mouth and folded over the wall 34 to form a cuff 41, and the container is sealed by crimping over its rim a closure 36 carrying a wax gasket 30, the oil content of which is partially exuded during crimping so that it fills the folds of the pleats and forms a hermetic seal, Fig. 9. In a modification, the bag 40 is tubular and the container is sealed at each end in the same fashion as the mouth is sealed above. In a second modification, the bag 40 is generally as in Fig. 8, but the base 35 is dispensed with and the wall 34 reduced to a band which supports the bag rim. In this, embodiment, the container is merchandized in an inverted position. In a third embodiment the bag 40 is dispensed with and the container is formed from aluminium and itself has a pleated rim to which a closure is attached.

Abstract: 1,153,628. Determining properties of liquid metals. MINE SAFETY APPLIANCES CO. Nov.1 1966, No.48933/66. Heading G1N. The concentration of combined oxygen in a liquid alkali metal in a closed loop heat transfer system is measured by contacting the liquid metal with an electrode 6 of a metal that forms an oxide more stable than the oxide of the alkali metal and measuring the subsequent substantially linear rate of electrical resistance increase due to formation of oxide on the electrode.
