Title: Improvements in Transistor Switching Circuits
Inventor: PLUMMER DEXTER ROBERT
IPC: H03K17/60
Filed: 1968-12-18
Abstract: 1,189,089. Transistor switching circuit. RANK ORGANISATION Ltd. 18 Dec., 1968, No. 60085/68. Heading H3T. A switching circuit which produces an output signal for a non-zero input above a certain threshold value comprises a common input 7 connected via respective, oppositely poled diodes D1, D2 to complementary transistors Q1, Q2. A biasing arrangement of diodes D3, D4 and a high value resistor R5 ensures that whichever transistor is turned on by the input signal the other transistor is then biased on. This results in a drop in positive potential at terminal 2 providing an output signal common to any non-zero input signal. The threshold level for the input signals is determined by the values of resistors R3, R4 and also resistors R1, R2 which are associated with an input amplifier A. R1 can be made variable to provide zero adjustment and the transistors may be replaced by Darlington pairs if high current flow through them is expected.

Abstract: 743,359. Grinding rotary cutters. SHILTON, F. Sept. 21, 1954 [June 30. 1953], No. 18135/53. Class 60 A jig for holding rotary cutters during grinding comprises a stand 11, an arbor 10 mounted therein for rotation about its axis and adapted to hold the cutter 15 to be ground, a dividing head 12 to hold the arbor in predetermined angularly spaced positions, and an index member 16 extending from the stand to a position for engagement by the teeth of the cutter 15. '.The stand 11 may be pivotally adjusted about an axis 23 and clamped to a base 13 by a pair of bolts 24 in engagement with an arcuate slot in the base, an indicator 27 and a scale 28 being provided. The arbor 10 is rotatably mounted in the stand 11 and restrained from axial movement therein by a conical portion 34 and an axially adjustable backplate member 32 which engages a ring 31 of anti-friction material. A pointer 35 arranged to be clamped in an angularly-adjusted position on the member 32 co-operates with a scale 40 secured to a stator 41 having a lug 43 engaged at opposite sides by a pair of screws 45 by means of which the stator may be given a limited angular adjustment. A spring-loaded plunger 50 is also carried by the stator 41 to co-operate with a series of peripheral recesses in a rotor 53 having a pair of arcuate slots 61 to receive a pair of bolts 60 on the backplate member 32 whereby the latter may be angularly adjusted in relation to the rotor. The index member 16 comprises a pair of rigid links 64, 65 pivotally connected to each other and to an angle bracket 68 adjustably clamped to the stand 11. To set up a cutter for grinding, the plunger 50 is brought into engagement with the rotor 53 at a position indicated by a line 59 which may be observed through an annular window 56, and the cutter 15 secured to the arbor 10 so that one of its cutting edges is disposed immediately in front of an abutment member 75 on the index member 16. The cutting edge is now brought into contact with the member 75 by adjustment of the stator 41 and the pointer 35 brought into line with the zero mark on the scale 40. Next, the two bolts 60 are slackened and the member 32 rotated until the pointer 35 indicates the correct cutting angle. In this position, the front face of the cutter tooth is vertical and in alignment with the flat face of a grinding disc 17. The rotor 53 enables the remaining teeth of the cutter to be brought accurately to grinding position. For the treatment of helical cutting edges, the stand 11 is skewed. The index member 16 may be replaced by a telescopic arm or other means which allow the member 75 to be moved clear of the cutter prior to grinding and the member 75 may be a point, cone or domed face or it may be in the form of a graduated face.

Title: Removal of fission products
IPC: G21C19/30
Filed: 1978-10-12
Abstract: In a liquid metal cooled nuclear reactor installation the long-lived fission products issuing from damaged fuel rods within the fission zone (3), which products are more volatile than the coolant itself, are concentrated in aerosols which the coolant forms in the covering inert gas blanket (7). The entrained liquid metal and fission products are precipitated in at least one vapour trap (10) through which the inert gas is passed. In a distillation device (14) at least one fission product, more particularly caesium, is distilled out of the liquid metal precipitated in the vapour trap(s) (10) before the liquid metal is conducted back into the coolant circuit. Calculated over a long period, a considerable reduction is thus achieved in the radioactivity due to deposition of fission products in the installation. <IMAGE>

Patent GB-2023708-A (GB)
Title: Arrangement at gutters
IPC: E04D13/064
Filed: 1978-10-03
Abstract: Arrangement at gutters in roofs for slope to the sides of the gutters, which have outlets in the form of sinks and spouts. The object of the invention is to produce a gutter of the aforesaid kind, which renders it possible to assemble a gutter corresponding to the special roof requirements with respect to the number of sinks, overflows etc. and to provide a gutter, which can be repaired without therefore requiring the entire gutter to be dismantled. The invention further renders possible an accurate horizontal positioning irrespective of possible differences in height in the carrying structure or the roof. Differences in height in this context are to be understood to refer to the small variations possibly prevailing in height position from one truss to the other and lying within permissible construction tolerances. The invention further ensures by simple means the prevention of ice formation at the gutter edges. The invention implies that at least one section (1) at the outer edge of the roof (outer section) is provided with at least one sink (6) having its inlet in the same plane as the bottom (2) of the section, a first outflow (8) connected to a second sink (7), and a second overflow (10) of higher location connected to a spout (9).

Patent GB-2048832-A (GB)
Title: Signature handling apparatus
IPC: B65H5/12
Filed: 1980-04-28
Abstract: The disclosed signature handling apparatus is for use with a saddle conveyor which moves signatures with a folded edge up along a path through a series of stations. The apparatus transfers signatures from the saddle conveyor to the infeed conveyor of a signature trimmer in a smooth motion and without abrupt changes in speed or direction. The infeed conveyor to the signature trimmer is located in a plane parallel to and above the path of the saddle conveyor. The apparatus includes a tucker blade mechanism which contacts the folded edge of the signature from below the saddle conveyor. The tucker blade mechanism moves the signature forwardly and upwardly from the saddle conveyor as it moves in a vertical plane through a path which is oblique relative to the saddle conveyor. A gripper finger assembly grips the signature from the tucker blade mechanism and continues the forwardly and upwardly movement of the signature and simultaneously rotates it about an axis parallel to the saddle conveyor. When the gripper finger assembly grips the signature from the tucker blade mechanism, it has a component of motion parallel to the path of the saddle conveyor. The signature is released into the infeed conveyor of the trimmer when it has a component of motion which is perpendicular to the path of the saddle conveyor and in the plane and direction of the trimmer infeed conveyor.

Title: Improvements in or relating to foam filtering
IPC: B01D47/04
Filed: 1980-06-18
Abstract: In order to increase the concentration of foaming agent in a liquid, a mixture of foaming agent and liquid is foamed to produce a foam layer (23) on top of remaining liquid (22). Foaming agents are surface active and are therefore present in greater concentration at surfaces, so by removing, and if desired degrading, the foam layer a fraction of the liquid which is relatively rich in foaming agent is obtained. The above described method may be utilised in order to recover or recycle foaming agent in a foam filtering or foam reaction system. In such systems a gas or gaseous mixture (8) is brought into contact with a bed of foam (11) which degrades to a liquid (13) containing a substance or reaction product extracted from the gas or gaseous mixture. This liquid may then be treated in situ or in a remote vessel (18) in order to recover and recycle foaming agent. <IMAGE>
