Title: Machine tool control system
IPC: G07C3/00
Filed: 1968-11-18
Abstract: 1,254,447. Machine tool details. SUNDSTRAND CORP. 18 Nov., 1968 [20 Nov., 1967], No. 29062/71. Divided out of 1,254,445. Heading B3B. [Also in Division G3] A control system for a plurality of machine tools each using a plurality of tools for performing different machining operations on a part comprises means for transporting tools from a central supply to any of the machine tools. As shown, Fig. 1, numerically controlled machine tools 20, each of which is a general purpose multi-axis machine tool capable of boring, milling and drilling, are supplied with parts 25 on pallets 26 from a common parts storage conveyer 40. The machine tools are controlled by an on-line computer 30. The parts 25 are supplied to a machine tool by a pneumatic, or hydraulic, ram 44 transferring a pallet to conveyer 70. The storage conveyer is searched by a selected read unit commanded by the computer and the part transferred by the ram and rollers to the machine tool. The finished part is returned to the storage conveyer. Collisions at intersections between rollers and conveyers are prevented by controlling transfer by gates 137 held closed by the interruption of a light beam 135. The computer 30 retains in its memory the instantaneous location of all parts and tools in the system and effects control of the machine tools accordingly. The parts storage loop 40 is fed from a warehouse arm 250, comprising conveyers 255 each holding a different basic part, from an input conveyer 60. The computer memory is updated in synchronism with movement of parts at photo-electric stations 134 reading process indicia on a work-piece. Transfer to a further parts loop is effected by a conveyer 61. The appropriate tools for the programme are selected from a fixed storage area 269 for each machine or from a tool conveyer 81 via a temporary storage conveyer 85. Tool transfer, Fig. 3, each shared tool is mounted in a car 83, running on rails 280, which is transferred to conveyer 85 by a ram extending a pair of short tracks across slots in rails 280. The car is disengaged from rails 280 and rolls along rails 300 by gravity until it strikes the legs 340 of a U-shaped member 342. The tool is then transferred to the spindle, not shown, of the machine tool by a conventional tool-changer 87 having a Y-shaped end claw 380. The member 342 is moved, to correctly position the car adjacent to the claw 380, by a motor, energized by the computer 30, driving a lead-screw 360. When the tool is returned to its car, the computer energizes the motor 350 in the appropriate direction to correctly position the car carrying the used tool in the machining programme. When the programme is complete the member 342 is withdrawn and the cars returned to the conveyer 80 through a gate 230. A tool is removed from the storage arm 269 by rotation under command of the computer and raising the tool by a ram to the level of the claw 380.

Title: Logic circuits employing negative resistance elements
IPC: H03K19/10
Filed: 1961-08-11
Abstract: 922,580. Semi-conductor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 11, 1961 [Aug. 18, 1960], No. 29082/61. Class 40 (6). [Also in Group XXXVI] A logic circuit comprises two two-terminal negative resistance devices connected in series across a source of conditioning pulses and a resistance between the devices such that on the application of the pulse the circuit has two stable conditions in which one device or the other is in the higher resistance state and the other in the lower resistance state. Fig. 5 shows two tunnel diodes 26 and 27 which during the presence of a conditioning pulse at terminals 8<SP>1</SP> and 91 will normally be in a preferred condition in which 26 has a low impedance and 27 a high impedance, the preferred state resulting from the bias supplied by a resistor 29a. A sufficient signal at 70a from the input terminals 12a<SP>1</SP> will cause the conductivity states of the two tunnel diodes to be the reverse when the conditioning pulse is applied. By suitable proportioning or biasing the input circuit AND, OR or a majority logic circuit can be produced. Resistor 28 increases the impedance of the circuit and may be chosen in magnitude such that oscillation during switching does not take place. The circuit may be restored by applying a pulse at 70a (Fig. 3, not shown), or by the termination of the conditioning pulse. The initial preferred state may alternatively be determined by choosing tunnel diodes of different characteristics and the input may be applied to a tap on the resistor 28. In Fig. 1 (not shown), the resistor 29a is connected between 9<SP>1</SP> and 20a so that the preferred state is reversed and in this case the input is applied to point 21a and the isolating diodes are reversed. A number of such logic circuits are connected in cascade, the conditioning pulse supply between terminals 8<SP>1</SP> and 9<SP>1</SP> being obtained from successive taps on a delay line, producing delays corresponding to the delays in the circuits.

Title: Wall coverings and methods of making, applying and removing same
IPC: B05C1/08
Filed: 1968-06-19
Abstract: 1,241,177. Adhesive coated wall covering. COMBINED PAPER MILLS, Inc. 19 June, 1968 [20 June, 1967; 22 May, 1968], No. 29144/68. Heading B2E. [Also in Division D2] A wall covering comprises a flexible base stock having an adhesive material applied directly to the surface which faces and comes into contact with the wall to which the wall covering is applied or to a barrier coating thereon, the adhesive material being partially e.g. 10-20%, in encapsulated form with the remainder of the adhesive material not being capsulated, and being tackifiable by the application of heat and/or pressure, without the need to moisten the adhesive material, the adhesive being heat-activatable at between 175‹F and the scorching temperature of the base stock. The adhesive may be present from 16 to 18lb. per 3000 sq. ft. of base stock. The adhesive may be reactivatable by heat and/or pressure after a first activation by heat and/or pressure, so as to permit stripping of the base stock from a wall at a subsequent time. The adhesive may contain a plasticizer. The adhesive coating may be applied in a liquid carrier e.g. water, and the coated stock subsequently dried. The adhesive coating may be applied to paper stock by forming a pool of the liquid-carried adhesive material between an applicator roll and a supporting roll during the paper making process, the applicator roll being rotated at a lower peripheral speed than the supporting roll, and the supply of liquid coating to the pool being carried out at a rate which, in conjunction with the speeds of the web and applicator roll, will substantially eliminate turbulence and splashing of the coating in the pool. The pool may be formed between the breaker stack and drier section of a paper-making machine. Alternatively, the adhesive may be applied to air-knife coating. The barrier coating e.g. of styrene-butadiene latex and kaolin clay, may be present from 8 to 10 lbs. per 3000 sq. ft of the base stock. The covering is positioned on the receiving wall, the dry adhesive material is activated and the covering caused to adhere to the wall by placing a heat and/or pressure source into contact with the exposed surface of the covering. Moisture may be added to the base stock, as contrasted to the adhesive, prior e.g. immediately prior, to placing the covering on the receiving wall. Covering using a retackifiable adhesive may be removed from a wall be placing on heat and/or pressure source into contact with the exposed surface so as to retackify the adhesive and stripping the covering from the wall while the adhesive is in that state. The base stock may be of paper, cloth, wood veneer, synthetic plastics or combinations thereof.

Abstract: 823,031. Windscreen cLeaners. TRICO PRODUCTS CORPORATION. Oct. 14, 1955 [Oct. 18, 1954], No. 29374/55. Class 138(1). A windscreen wiper for a wrap-around curved windscreen comprises an oscillatory driving shaft 17, Fig. 2, which drives a wiper arm 19, 20 and a wiper blade assembly 23, 24, 27, Fig. 5, the arrangement being such that means 41, 42, 38, Fig. 3, connecting the blade assembly to the wiper arm acts to maintain the assembly substantially normal to the windscreen surface throughout its arc of operation. The wiper arm comprises a section 19 mounted on the drive shaft 17 and an outer section 20 pivoted at 21 to the section 19. Detachably connected to the outer end of the arm section 20 by means of a lug 32 is a fitting 31 provided with spaced ears 34 carrying a cross-pin 38. The ears 34 loosely embrace the primary yoke 28, Fig. 5, of a wiper arm pressure distributing superstructure 27 of known type, and the pin 38 passes loosely through an opening 36 in one side wall of the yoke 28 and through a slot 37 in the other wall of the yoke. The pin 38 is positioned between a leaf spring 39 rivetted to the yoke. at 40 and a plate-like central member 41, Fig. 3, slidable in the yoke. The member 41 is connected at 48 to one end of a link 46 passing through a slot 47 in the yoke 28 and connected at its other end to a lug 49, Fig. 2, on a collar 50 secured by a key (not shown) and a nut 52 to the bearing 18 for the drive shaft 17. As the arm 19, 20 oscillates with the shaft 17 clearly the member 41 will be reciprocated to-and-fro in the yoke. As the arm oscillates over the highly curved portion at the side of the windscreen a cam part 42 on the member 41 engages the pin 38, Fig. 5, against the urge of the spring 39 and tilts the blade assembly 22 and the superstructure 27. When the arm and blade are moving over the frontal portion of the windscreen the member 41 is positioned as shown in Fig. 3, and the pin 38 is the parallel to the base wall of the yoke 28 and maintained thus by the leaf spring 39. In another embodiment described with reference to Figs. 9-12 (not shown), the control member 41 is formed as a channel the walls of which have oppositely inclined cam shots. The cross-pin 38 in this case passes through vertical slots in the walls of the yoke 28 and through the cam slots. Specification 823,032 is referred to.
