Patent GB-1509779-A (GB)
Title: Arrangement for the forming of work pieces
IPC: B21J15/30
Filed: 1975-10-31
Abstract: A shaft (30) provided with eccentrics (35, 36) is rotatably mounted in a body of revolution (3). The eccentrics impart to a hoop-shaped oscillating element (4), the axial limbs of which are arranged laterally on the body of revolution (3), an oscillating motion. The tool (7) is connected to the oscillating element (4) and, as a result, this performs a wobbling working motion. Superimposed on this wobbling motion is a rotary motion since the body of revolution (3) is driven independently of the shaft (30) driving the wobbling motion and thus rotates the oscillating element (4) during the execution of the wobbling motion. The tool (7) is the setting head of a riveting tool and the deformation process results in a high quality of shaped pieces with the use of relatively small deformation forces due to the punctiform backwards and forward and rotary rolling motion of the working surface of the riveting tool. <IMAGE>

Title: Information switching and storage circuitry
IPC: G11C11/414
Filed: 1968-09-25
Abstract: 1,203,178. Matrix stores. R.C.A. CORP. 25 Sept., 1968 [2 Oct., 1967], No. 45551/68. Heading G4C. [Also in Division H3] A bi-stable 10, Fig. 2, used as a memory element consists of two cross coupled transistors 30, 40 each having three emitters, the first emitters 34, 44, and the second emitters 35, 45 of the transistors being connected to respective drive lines 11-1, 12-1, and the third emitter 33, 43 of each transistor being connected respectively to first and second current drive circuits including transistors 50, 60 via lines 15, 16. The transistors 30, 40 have collector resistors 36, 46 connected to a reference (earth) potential through a further resistor 37 whereby the ON transistor is biased from the intermediate point 38 via the collector resistor of the OFF transistor to prevent it saturating. A matrix of bi-stables 10 is used (Fig. 1, not shown) as a store, selection of one bi-stable being accomplished by application of a positive potential at the inputs X1, Y1 of appropriate X and Y select driver transistors 50, 54 whereby the lines 11-1, 12-1, which normally have a potential below that of lines 15, 16 and therefore control the transistors 30, 40, are raised above that potential so that control of transistors 30, 40 is taken over by lines 15, 16. Write transistors 60, 70 forming part of the read-write circuitry (right-hand part of Fig. 2) can then render transistor 30 or transistor 40 conductive according to their inputs W 0 , W 1 ; if W 1  goes positive, line 16 will go positive, transistor 40 turns OFF, and transistor 30 ON. Reacting of the bi-stable occurs upon selection by the X 1  and Y 1  signals; if,for example, transistor 40 is ON and transistor 30 is OFF, then the current from transistor 40 flows, upon selection, via line 16 through a constant current transistor 75; and a transistor 73 normally conducting through transistor 75 has its current reduced. Its collector 73c rises in potential and an emitter-coupled pair 90, 91 change state to give a positive output at R 0  via a transistor 94. A reference voltage for the transistors 73, 75, 91 is derived from a chain of resistors 100, 103, 104 and diodes 101, 102, 105, the first two diodes providing temperature compensation. The same reference voltage is supplied also to transistors 63, 65, 81 of an identical arrangement which controls the line 15, and gives a read output at R 1 . The read circuits also function to provide at the R 1 , R 0  outputs an indication of circuit response to a write instruction.

Abstract: 1300294 Tubular heat exchangers; steam generation WAAGNER-BIRO AG 24 Sept 1970 [26 Sept 1969] 45673/70 Headings F4A and F4S In a radial flow heat exchanger comprising an annular array of tubes 3, uniform through flow of a first heat exchange fluid radially across the tubes from an inlet 12 to an outlet 13 is achieved by a fluid-guide arrangement comprising inner and outer tapered tubular walls 1 which together with inner and outer perforated cylindrical walls 2 define a receiving chamber 14 and a discharge chamber 15 for the first fluid. As shown the tubes 3, which are in the form of flat spirals, are arranged in groups 4-8 disposed in chambers defined between annular baffles 9. The sizes and distribution of the openings of the perforated walls are arranged so that an equal amount of fluid flows through each of the groups 4-8. Ring shaped covering sheets can be placed around selected areas of the perforated walls if required to compensate for irregularities in the through-flow. The flat tube spirals can be replaced by a plurality of circular sections adjacent ones of which communicate with and surround each other. A plurality of supply and discharge headers 10 and 17 communicate with the tubes 3 through connecting tubes 11. In a modified embodiment (see Fig. 1, not shown) the tubes may be arranged to form inclined spirals, the baffles in this case being frusto-conical in shape. In another embodiment (Fig. 4) the several groups of tubes are arranged in sector-shaped arcuate chambers around the central axis of the heat exchanger, the tubes in each sector being of sinuous configuration and extending between supply and discharge headers (10, 17) disposed within the chambers. The heat exchanger may be used as a steam generator with the core of a gas-cooled reactor being situated at its central region 16.

Abstract: 1,153,506. Photo-conductive composition. EASTMAN KODAK CO. 16 Oct., 1967 [14 Oct., 1966 (2)], No. 47134/67. Heading H1K. A photo-conductive layer comprises a dye and a hydrophobic polymeric material in a twophase heterogeneous state and having a wavelength of maximum absorption which is different from that of the dye and polymeric material in a homogeneous state. The dye is preferably a pyrylium, thiapyrylium or selenopyrylium dye or salt thereof, numerous examples of which are listed. The polymer is preferably a polycarbonate but others are listed, e.g. polyvinyl ethers, polythiocarbonates, polyesters, poly-α-olefins and phenolic resins. The photo-conductor may be an inorganic photo-conductor but preferably an arylamine including polymeric triarylamines, e.g. 4,4<SP>1</SP> - benzylidene - bis - (N,N<SP>1</SP> - diethyl - m - toluidine). An electrophotographic element is made by forming the photo-conductive layer on a conductively coated sheet of polyethylene terephthalate or a metal foil. The conductive coating may be AgI, Cu 2 I 2 , Ti, stainless steel, Nichrome (Registered Trade Mark), vacuum deposited Ni, Al or Ag, a semi-conductor disposed in a resin or the sodium salt of a carboxyester lactone of maleic anhydride and a vinyl acetate polymer. A subbing layer of a terpolymer of itaconic acid, methyl acrylate and vinylidene chloride may be used on the support whilst a barrier layer of cellulose nitrate may be provided between the conductive and the photoconductive layer. The two-phase heterogeneous photo-conductive layer may be formed by (a) subjecting a solution of the components to highspeed shearing, (b) adding a small portion of a sheared solution to an unsheared solution, (c) contacting the formed layer with vapours of a solvent capable of softening the layer, (d) including a high foiling solvent in the solution which persists during drying of the layer, (e) inhibiting the evaporation of solvents from the solution or (f) immersing a homogeneous coating in a solvent. The layer may appear homogeneous to the naked eye, but under a magnification of 2500 X granular particles of 0À1 to 25 Á can be seen. Other layers may have macroscopic heterogeneity.

Abstract: 1,096,018. Photo-electric line followers. MORFAX Ltd. Nov. 17, 1965 [Nov. 20, 1964], No. 47343/64. Heading G3N. [Also in Division G1] In an outline following apparatus of the type in which light sensitive resistors 32 are linearly reciprocated transversely to the image of the line or template being followed, the resistor movement is produced by a synchronous motor 35 of the self-phasing type whose shaft 36 includes an eccentric driving pin 37 engaged in a slot in a reciprocable carrier 33 for the resistors. The signal produced by the resistors 32 has a varying phase according to the displacement of the centre of the resistor scan from the line being followed and is applied to a servoamplifier SA (of the limiter type) which feeds a servomotor 41 for rotating, through gears 42, 43, a support tube 25 for the members 32... 37, this rotation maintaining the resistor scan transverse to the line. The gear 43 also meshes with the gear 44a of a resolver 45 which supplies output signals to amplifiers XA, YA controlling X and Y axis drive motors 17, 12, whose speeds and directions of rotation are thus varied to cause the follower head assembly 5 to move along the line. One of the resistors 32 is arranged to be "forward-looking" so that it produces a "slow down" signal to the motors when sharp changes occur in the line being followed. The movement of the head assembly 5 over the line is effected by a mutually-perpendicular parallel-rail arrangement, Fig. 2 (not shown) and may be directly coupled to a machine tool, offset of the head 5 to take account of the tool radius being provided by a horizontallyadjustable cross slide 26 carrying the optical system and the light sources 27-29, 31. Alternatively the output from the resolver 45 may be recorded on magnetic tape, or the X, Y drive motors 17, 12 may carry impulsing wheels adapted to produce digital signals, e.g. by photo-electric scanning methods, which signals are recorded on magnetic tape subsequently used to control a separately-located machine tool. The head 5 carries slip rings and brushes 51 for electrical connection to the members carried therein, the synchronous motor 35 and lights 28 being energized from the same A.C. supply.

A full-fashioned machine has a loose point bar shiftable several needles spaced by a fluid operated piston, to effect a cable stitch. The mechanism for transfer in one direction - the right as shown, comprises a cam block 96 mounted on a slide 98 fixed to the point bar and a rotatable cam block 122. One end of rod 118, passing through block 96 is secured in block 122 and the other abuts the end of piston 174. The piston is enclosed in a movable cylinder 160 secured to block 96 by a strut 166. Before each loop transfer the point bar and slide are spring biased to the left until stop 94 abuts a pattern peg 80. When the loops are engaged air is admitted to the right hand end of the cylinder. The cylinder, block 96 and slide 98 are thus pushed to the right until the block abuts stop 127. The extent of the transfer is determined by the position of the stop, whose position is fixed by the height of the abutted peg 80. After the transfer, air enters the left hand end of the cylinder, and the slide returns to the neutral position shown, loops may be transferred one needle space in the opposite direction by rotating the cam block 122 so that block 96 engages its low portion.
