Abstract: 1430396 Tractor hitches LOCKHEED MISSILES & SPACE CO INC 12 Dec 1973 [26 Dec 1972] 57620/73 Heading A1P [Also in Division B7] The sections of an articulated vehicle respectively support an insertion member 74 and a socket member 78 of a releasable articulated steering joint 16, the section bearing the member 74 having means for varying the horizontal and vertical angular position of the member to align it with the socket member during coupling. The insertion member is pivoted about a vertical axis 82 to the frame (26) (Fig. 1 not shown) of one section and is moved in the horizontal plane by rams 38, 40 mounted on the frame. Rods 54, 56, 62, 64, 66, 68 connect the joint to the steerable wheels 32 of the vehicle section. The wheels at each side of this vehicle section are interconnected by walking beams (30) (Fig. 1) which are pivoted about a central horizontal transverse axis to the frame and are angularly adjustable relative thereto by actuators 126. Variation of the walking beam/frame angle will vary the vertical position of the insertion member. The insertion member includes inner and outer housings 90, 84 which are relatively rotatable to a limited degree, as defined by interengaging pins 86 and slots 88, a locking flange 130 surrounded by a locking ring (100) (Fig. 4, not shown) and a tapered portion 128 having cylindrical support surfaces (110) (108) (Fig. 4) at either end thereof. During coupling locking flange 130 engages flange 116 of the socket member and the cylindrical support surfaces engage complimentary socket surfaces 118, 120. A socket guide member 112 engages a recess (114) (Fig. 4) on the insertion member during coupling to ensure exact alignment. The insertion member is provided with a drive shaft (102) (Fig. 4) having a flange 104 extending therethrough for supplying power to the non- powered section of the vehicle.

Abstract: 1,268,406. Semi-conductor device. MATSUSHITA ELECTRONICS CORP. 9 Dec., 1969 [10 Dec., 1968; 27 Dec., 1968], No. 60078/69. Heading H1K. A pressure sensitive semi-conductor device comprises a four layer structure, a metalsemi-conductor contact forming a rectifying junction on one of the non-outermost regions of the structure, and a pressing means for the metal-semiconductor junction. The device is constructed by epitaxially growing a phosphorus doped silicon layer 2 on one surface of a P-type silicon substrate 1, forming a phosphorus diffused region 4 in the other surface, forming an oxide layer 8 on the layer 2, and through windows in the oxide forming a boron doped region 3 and depositing a molybdenum contact 5 forming the Schottky junction. An aluminium electrode 7 contacts the region 3, and the pressing means may be a sapphire needle 6. The device may operate as a thyristor, with a control electrode formed by the Schottky junction under the influence of the needle 6, increasing pressure on the needle causing the device to become conducting. In an alternative embodiment, the region 4 may be formed by depositing a gold-antimony alloy on to the bottom surface of the substrate, and then thermally fusing the device to a metal base (18), Fig. 3 (not shown), the heat causing an alloyed junction with the semi-conductor to be produced, forming the fourth region (19). An NPNP-structure may also be formed using niobium as the Schottky contact and a goldgallium alloy to form the fourth region.

Abstract: The invention relates to apparatus for breaking up vegetable matter, particularly to render such matter suitable for composting, comprising at least one elliptical blade 8 mounted obliquely on a rotatable shaft such that it generates a cylinder as it rotates. Vegetable matter is fed to one side of the cylinder, at which an edge is formed for shearing engagement with the rotating blade. The invention may be embodied in either a stationary or a mobile form. In the former, the "cylinder" is normally positively defined by a drum having inlet and outlet openings in its cylindrical surface, an edge of each opening defining a shearing edge, while in the latter, the shearing edge is conveniently formed on a plate extending around a part of the cylindrical surface to the point of discharge. <IMAGE>

Title: Isotopically selective photoionisation
IPC: B01D59/34
Filed: 1978-12-19
Abstract: Apparatus and process for isotopically selective multistep photoionization in which the ionizing step is tuned to produce a specific transition to an excited state above ionization for which the ionization cross-section is substantially greater than for ionization transitions in general. The autoionization transition to an ionized state is made from a highly excited bound state reached in one or two isotopically selective energy jumps from the ground state or other low-lying levels. The isotope shift for the ionization transition is small compared to the bandwidth of the ionization transition and relatively broad band photoionization radiation covering the entire absorption line can be employed. A technique is also shown for identifying the ionization transitions of augmented cross-section.

Abstract: A safety device for a heat engine, for example an internal combustion engine 2, used in an atmosphere which is dangerous because of the likelihood of its catching fire or exploding, comprises means 1 for blocking the fuel inlet or closing an air inlet opening to the engine associated with means 5 for maintaining the blocking means 1 in the open position. The means 5 is retracted when an adverse condition is detected by a transducer (not shown) monitoring a condition of use of the engine.

Title: Holding a laminar article in a planar configuration
IPC: G03F7/20
Filed: 1979-01-23
Abstract: A laminar article (14) is held in a planar configuration by urging it, for example by means of a vacuum (applied via 16) against a plurality of small-area abutments (18) which define a planar surface. The smallness of the area of the abutments (18) reduces the probability of there being any intervening dirt particles to perturb the planarity of the article (14) and there is a tendency for any such particles to be squeezed out. Preferably the article (14) is given a slight lateral movement after bringing it into contact with the abutments (18) to dislodge remaining intervening dirt particles. The invention is particularly applicable to holding semiconductor wafers during pattern exposure but may be used to hold workpieces during polishing, grinding or machining. <IMAGE>

Title: Control of stepper motors
IPC: H02P25/08
Filed: 1979-07-16
Abstract: Windings 23, 24 of a variable reluctance stepper motor are alternately energised by respective transistor bridges A-D, E-H controlled by a processor receiving the outputs of comparators 77-80, each of which receives a signal synthesized by the processor to have an unperturbed waveform corresponding to the winding voltage when the motor is stationary and a signal of sensed winding voltage having a perturbed waveform related to the motor movement, whereby the processor first confirms that the motor is moving and then energises a winding reversely to its previous state. The signal waveform intersections define two crossing points dependent on the motor load, the processor respectively using the first point or the second point, Figs. 8A and 9B (not shown), to energise the windings according to whether optimum acceleration or deceleration is required. Load variations during driving automatically vary the crossing point and energisation instant being used, further variation occurring in dependence on motor position or velocity when the circuit is included in a programmed closed loop control system. Constructions are described, Figures 1 to 4 (not shown) of linear and rotary cylindrical or disc motors providing the characteristics of Figures 8A and 8B. Also described is a method of fabricating the stator and bearing system of the linear motor. <IMAGE>
