Title: Mixing device for particulate material
Inventor: MASHAM ROGER DEREK
IPC: G03G15/08
Filed: 1984-06-05
Abstract: A mixing device, of the kind known as a cross-mixer for particulate material. The device includes three rows (71, 72, 73) of chambers, with the chambers (e.g. 81, 82) of each row alternately diverting the particulate material, dropping under gravity through the device, to the left or to the right by the use of an exit aperture (90, 91) at the bottom of each chamber (81, 82) which is displaced to the left or to the right from a position vertically below the mouth (116, 104) of the chamber at the top of the device. The mouth and exit apertures of the chambers of different rows are aligned in such a fashion that on successive recirculations of an elemental volume of the material through the device there is systematic movement thereof from end to end of the device, with simultaneous movement of material from left to right and from row to row, and from right to left and from row to row. The mixing device, which in use is completely submerged in the particulate material comprises two inter-fitting castings, each having vanes (83, 84, 84) projecting from a dividing plate (77), the dividing plates separating the rows, and the vanes defining the chambers. <IMAGE>

Title: Trigger switch circuit and electric hand tool incorporating the same
Inventor: WEIGERT HAN
IPC: H03K17/73
Filed: 1984-09-24
Abstract: An electrically powered staple gun has a driver solenoid 30 to which is applied a boost of power by a trigger circuit (Fig. 5) on opening of a normally closed trigger switch 46. The switch 46 has a pair of flexible resilient leaves 54, 56 having their one ends fixed to a printed circuit board 44 carrying the trigger circuit. The leaf 54 has a free end engageable by a trigger 16 to open the switch.

Patent GB-847305-A (GB)
IPC: G11C11/06
Abstract: 847,305. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. (Standard Elektrix A.G.). April 30, 1958, No. 13683/58. Class 40 (9). [Also in Group XIX] In a magnetic memory matrix in which a full current reading pulse I L  and a half current writing pulse I S/2 , Fig. 2, are applied to each row winding in turn, the trailing edge of the writing pulse is arranged to initiate the application of a reading pulse to the next row of the matrix so that transition from one row to the next takes place without delay. Selected column windings are energized simultaneously by half current writing pulses during the period of each row writing pulse, and the matrix may have separate reading and writing generators for each row and column winding or may utilize common reading and writing generators for each co-ordinate. As shown, in Fig. 3, each row winding 2 of a ferrite core matrix 3 is connected to an individual reading pulse generator 4 and a writing pulse generator 5, row scanning being controlled by a circuit 6. Each writing pulse generator is directly connected to the reading pulse generator in the next row so as to initiate the reading pulse generation. In an alternative arrangement, Fig. 5, writing and reading pulse generators 9, 11 are connected to all the row windings (n- 1) to (n+2) over transformers T S , T L , transistors 101-103 and transformers T n-1 -T n+  2 . In operation, a pulse P causes generator 9 to apply a writing pulse to a selected row winding by way of a conductive transistor and a transformer winding W1. At the end of the pulse, generator 11 is rendered operative over link 14 and immediately applies a reading pulse over the same conductive transistor and over winding W2 of the adjacent transformer to the next row winding, the two windings W1, W2 of adjacent transformers being segregated by rectifiers 7, 8. The transistors are rendered conductive in succession to enable each row winding to be subjected to both read and write pulses in turn, the transistor switching operation taking place after the application of a reading pulse so that a writing pulse is applied over the other winding W1 of the associated transformer.

Title: Boring bar
Inventor: WYATT ANTHONY PAUL
IPC: B23B31/107
Filed: 1985-03-15
Abstract: A modular boring bar has three sections (10,12,14) one section (10) engages in and is secured to the boring machine. Another (14) carries a cutting tool (82). Adjacent sections are interconnected by frusto-conical front portions (60,84) which engage in cooperating bores (40,72) in the rear of the adjacent section. A transverse threaded bore (44) across the rear of each section cooperates with a partly-tapered bore (64,86) in the front portion of the adjacent section so that a partly tapered, partly threaded pin 52 can be engaged in the bore and wedge against one side of the tapered bore (64,86) to draw the sections together and provide considerable axial rigidity. <IMAGE>

Title: Computer system
IPC: G06F9/22
Filed: 1985-06-17
Abstract: A computer system has a control unit 101, an input/output unit 102, and plurality of execution units 103, connected to a network bus 100. The network bus 100 has data lines corresponding to the number of units connected to it, and each execution unit has a data line associated with it in which it signals its status. These status signals may be used to control the sequence of operation of the execution units. Details of the structure of the execution units are disclosed, as is the use of the computer system in an image recognition device. Each execution unit includes a bank switched memory (306, Fig. 4) which permits bidirectional transmission between a transmission control processor (301) and an execution processor (302). A program memory for the 16 bit execution processor uses 24 bit words. The excess bits are used to address 2 megabytes of RAM via intermediate translation (Fig. 4). The processor clock rate is automatically adjusted in accordance with operations to be performed.   <IMAGE>

Title: Equipment for playing a game
Inventor: BOYS GRAHAM ANTHONY
IPC: A63F7/00
Filed: 1985-12-20
Abstract: Equipment comprises a board (4) which when located alongside a playing area provides the means by which a ball may be skilfully directed towards that area. Two parallel channels (5, 6) are provided, with a semicircular wall (7) enclosing them at one end and a container (3) for at least two balls at the other. The semicircular wall (7) guides and transfers a ball propelled along the outer channel (5) to the inner (6) and reverses its direction, the channels being situated close enough to each other to ensure that the transferred ball moving along the inner one (6) will be brought into collision with a second ball when propelled along the outer (5). The outer channel (5) is wide enough to retain its ball following a collision and the inner one (6) is narrow enough not to. The point at which the ball leaves the inner channel (6) is determined by the relative velocities imparted to both balls and the interval allowed between them, as are the angle and velocity when doing so. The playing area may include holes for receiving the balls, or targets much as skittles. <IMAGE>
