Title: Machines for shelling nuts
Inventor: MATSUMOTO HARUYOSHI
IPC: A23N5/00
Filed: 1966-11-29
Abstract: 1,116,758. Machine for shelling nuts. CASHEW CO. Ltd. 29 Nov., 1966, No. 53483/66. Heading A2Q. In a machine for shelling cashew nuts, one at a time consecutively, the rising flight 7, Fig. 3, of a vertical, endless, intermittently moving bucket elevator passes through a hopper 5 containing nuts, and collects one nut in each rising open-ended bucket 8. Reciprocating transferring and re-orientating mechanism B then locates each nut, in the position shown in Fig. 10b in a grooved trough 11, on the upper flight 9 of a horizontal, endless, intermittently moving conveyer 2, which carries the nuts to reciprocating rocking devices 123, 125 and 124, 126, Fig. 5, which carry each nut, through a channel 120, into the space between two rubber grippers 57 provided with pins 56. The grippers are then moved towards each other to grip the nut, and are then rotated. A rotating circular saw 80 is then swung into contact with the rotating nut to make a peripheral cut 131 around it, Fig. 10c. A pivoted, reciprocating splitting device 93, Fig. 8, moving in the direction d then rides over the gripped nut, and is then moved in the reverse direction c to locate the nut (now released from the grippers) between lower supporting members 92 and shell-separating members (104), Fig. 9 (not shown), having edges 103, which enter the cut 131. The pointed end of a wedge 107 is then received between the members (104), which are thus forced apart to split the shell into two parts, and release the kernel, Fig. 10d.

Title: Improvements in method of Forming a Metallic Oxide Article
IPC: H01M8/02
Filed: 1966-11-30
Abstract: 1,168,259. Moulding metallic oxide articles. GENERAL ELECTRIC CO. 30 Nov., 1966 [1 Dec., 1965], No. 53682/66. Heading B5A. [Also in Division C1] Refractory bodies, e.g. a solid electrolyte for a high temperature fuel cell, are formed by the plasma arc spraying on to a removable mandrel of metallic oxide powder particles comprising a first finely divided metallic oxide of unstabilized zirconia or thoria, intermingled with a second stabilizing metallic oxide of one or a combination of calcium, yttrium, ytterbium, or mixture of rare earths. The articles serve as a low resistance ionic conductor by virtue of the anion vacancies generated upon cathodic substitution of metal from the stabilizing metal oxide. The particles may also include one or more further oxides of iron, cobalt, nickel, titanium, zinc, zinc and lead mixture, and 2 weight per cent to 40 weight per cent uranium dioxide. Alternatively the one or more further oxides may be in the form of separate particles. The particles are produced as spherical agglomerate particles by spray-drying from a slurry. The plasma arc spray gun 11 employs a carrier gas, e.g. argon, which flows through nozzle 12 across which an arc is established with an electrode 13 so that the gas is ionized and oxide powder entrained in the gas is sprayed as a melt on to a rotated mandrel 14 of copper or aluminium which is subsequently dissolved away by nitric or hydrochloric acids respectively. The mandrel may alternatively comprise a flat plate. Composite bodies may be made by successively plasma arc spraying either one of the metallic oxide powder particles or further oxide particles on to the other on the removable mandrel. Alternatively, the metallic oxide powder particles may be plasma and are sprayed between layers of the further oxide particles. Examples are given of suitable compositions of the metallic oxide powder particles comprising ThO 2  with 4% CaO or Y 2 O 3 ; ZrO 2  with 9 to 19% CaO or Y 2 O 3 , alone or with 2 to 40% of the further oxides; ZrO 2  with 26À2% Yb 2 O 3 .

Abstract: 1286809 Photo-electric line followers O R FRISCH and G S B STREET 3 Nov 1969 [12 Nov 1968] 53685/68 Heading G1A [Also in Division G4] Apparatus for positioning a pair of mirrors 10 (one of which is shown in Fig. 1) to steer a light beam comprises, for each mirror, a store 22 for storing the required position of the mirror and an interferometric system, e.g. a Michelson system, for determining the direction and displacement of the mirror by counting in a scaler 21 pulses derived from phase displaced signals from photo-cells 17, the count being compared in a comparator 26 with half the required position to accelerate the mirror in the correct direction until the half way position is detected when the mirror is decelerated. When the set position is approached a "damped well" mode is initiated in which the required direction of movement and the actual direction of movement are determined and a greater force is applied to the mirror when it is moving away from its set position than when it is approaching it. In the normal load of operation the comparator energises first one of two transistors (34, 35), Fig. 2 (not shown) to apply current in one direction to the driving coils of the mirror and at the half way position energises the other transistor to reverse the current direction. At the next reversal of direction of movement of the mirror one or other of two transistors (34<SP>1</SP>, 35<SP>1</SP>) is energized according to the direction of current required to return the mirror to the set position, the actual direction of movement resulting in a signal to one of two groups of diodes (51, 52) so that increased current is applied if required. The apparatus may be used in a line following system in which the sleeved beam is a laser beam scanning in a circular path the line to be followed. The signals produced as the beam crosses the line are utilzed to control the movements of the mirrors.

Title: Manufacture of supports for semiconductor devices
IPC: H01L21/50
Filed: 1973-11-24
Abstract: 1449212 Welding by pressure FERRANTI Ltd 21 Nov 1974 [24 Nov 1973] 54644/73 Heading B3R In making supports comprising support members having secured thereto pieces of tape of a material suitable for bonding semi-conductor devices to said support members, a tape of said material is fed intermittently, by a reciprocating dog, to a means severing pieces from the tape of length determined by the dog reciprocation, and each of the severed tape pieces is removed from the severing means, in the intervening period between tape feeds, and transferred to a selected part of the support member where it is secured to said selected part. The tape may be of gold for bonding of gold or aluminium wires or a silicon wafer to the support member. The semi-conductor device may be a transistor or integrated circuit bonded to a lead frame, and said bonding may or may not provide an electrical connection. As shown, a gold tape 13 is fed by a reciprocating dog to a severing means. The dog is in the form of a needle 22 which is lowered to identingly or piercingly engage the tape only during tape-feeding forward reciprocation of the dog. The severing means comprises a vertically reciprocating knife 44 co-operating with a fixed knife 46, the knife 44 being upwardly moved against the bias of springs 47 to sever the tape. Feeding reciprocation of the dog, tape engagement lowering and release lifting oscillation of the dog, and reciprocation of the knife are derived from constant speed rotation of a beltdriven shaft 15, via, respectively, a cam 20 acting through a bell-crank lever 36, 34 and spring returned rod 25, a cam 21 acting through a lever 29, a link 28 and a bell-crank lever 27, 24, and a cam 40 acting through a lever 42. A severed tape piece 13<SP>1</SP> is held over the knife 44 and is transferred and lowered on to a selected part of a lead frame 60 by a suction nozzle 51 movable by an indexing means 53. The frame 60 is part of an integral strip of frames which is indexed by fingers 65. A heated platen 66 carries each tape piece to be heated and thereby secured to the frame, to provide a uniform thickness coating despite deformation of the tape by the dog. The tape piece may be 1 mm. square and 25 microns thick. In an example application in respect of a semi-conductor wafer including a transistor, the collector is bonded to the selected part which is integral with one of three conductors of a lead frame, and gold wires are bonded to the emitter and base contacts and thermo-compression bonded to the other two lead frame conductors. The semiconductor devices on a lead frame strip are encapsulated in epoxy resin following which the lead frames are separated. In an alternative embodiment (Fig. 5, not shown) the needle is replaced by a frictionally engaging dog comprising a metal member having a coarse or roughened tape engagement surface or comprising a rubber pad.

Title: System for processing coded pulse data
IPC: B61L25/04
Filed: 1972-11-30
Abstract: 1397995 Bar code reading system BENDIX CORP 30 Nov 1972 [13 Dec 1971] 55368/72 Heading G4M A bar code reading system for rectangular or circular labels has a light source such as a laser, a rotary reflector and a photo-electric sensor (Fig. 7, not shown). The labels have a wide introductory dark bar or ring, a narrow separating light bar or ring, data bars or rings of the same width and containing both light and dark bars the wider of which determines the bit value, a narrow dark end of data bar or ring and for the circle a light centre of label section followed by the rings in the reverse order (Fig. 3, not shown) or for the rectangular label a light wide bar and a narrow dark bar (Fig. 2, not shown). The labels are carried on containers on conveyers (Fig. 7, not shown), and a photo-cell is used to detect the presence or absence of each container.  Detection of a container by Box Detector 91 (Fig. 4B) sets flip-flops 111 so that pulses are supplied to a counter 114 which is set to receive a fixed number dependent on the slowest speed of the container. If the counter is reset while the Box Detector is still active an alarm is set off to indicate a failure in the system. Data from the label and clock signals are fed to a sync unit 31 which produces TL signals at each transition from a light bar to a dark bar and TD at transitions from dark to light bars. The output on line 34 is synchronized with the clock and feeds counters 37, 42 such that a count representative of the length of light and dark bars respectively is obtained. The counts are fed via buffers 44, 47 to an adder 48 and a comparator 49 where the sum is compared with predetermined upper and lower limits and if a valid comparison occurs the limits are fed to a State counter 51. The outputs of counters 37, 42 are fed to the state counter and produce state changes corresponding to the introductory bar, the narrow bar, the data bars, the centre or end bars and the inverted data for a circular label for which States ST0-9 are produced. The data from the buffers is fed to a comparator 54 which compares the light count with the dark count to see which is the larger and whether the bit is "0" or "1". Data from the comparator is fed to a shift register in a direction depending on whether the label is read correctly or in reverse. For a circular label both occur and the first half is held in store 71 to be compared with the second. After a predetermined number of comparisons the data is transferred to an output buffer 82. The State counter 51 is arranged to produce an error signal if inconsistent readings occur i.e. a dirty mark is mistaken for a dark bar and a false state change is created. A plurality of labels may be read and the most significant and least significant identified. Successive rectangular labels are arranged inverted (Figs. 7, 13, not shown).

Abstract: 1,174,670. Electric couplings. " P & B " ENG. CO. Ltd., and H. W. WILLIAMSON. 22 Nov., 1968 [15 Dec., 1967], No. 56978/67. Heading H2E. An electrical connector, for applying a temporary earth to a high-voltage conductor, comprises two jaw members 1, 2 pivotally connected by a pin 3, and a longitudinally extending clamping member 8, which screws into an upper portion 12 of the first jaw member 1, the screwing action producing relative longitudinal motion of the member 8. At one end of said member 8 is fitted a thrust member 9, comprising a cylindrical portion 92, and a frustoconical portion 93, the portions 92 and 93 being desired to abut respectively against a partcylindrical surface 14 of the first jaw member 1 and an inclined surface 24 of the second jaw member 2 so that if the clamping member 8 is rotated anticlockwise (as shown) the upper portions of the jaw members are forced apart and the lower portions are urged together, so tightly gripping a conductor between them, in either of the positions shown in outline. Earthing connection is made by means of the earthing lead 10. A synthetic rubber washer 81 is provided on the threshold portion of the clamping member 8, and a cross portion 82 is also fitted by means of which the member 8 is rotated when it is attached to the end of a long operating pole. The shape of the connector obviates the need to have the pole perpendicular to the conductor, an angle of 20 degrees to the wire being sufficient in the embodiment illustrated. Before the connector is presented to the conductor, the synthetic rubber washer is compressed between the upper jaw portion 12 and the thrust portion 9, so that the resulting friction prevents the weight of the connector and lead 10 from rotating the connector about the pole axis. To facilitate engagement of the connector with a conductor, the lower jaw portions 17, 27 are biased together by a spring 6 and have ends splayed apart.
