Title: Plastic recipient for culture of mushroom spawn - with chimney extension through which inoculation is effected
IPC: A01G1/04
Filed: 1972-11-30
Abstract: The chimney extends upwards from the centre of the recipient and is closed by a cap having a shirt which slides easily over the external surface of the chimney. The top of the cap is pierced by a central hole and the base of the cap holds a number of thicknesses of filter paper; the periphery of this paper is compressed between the upper edge of the chimney and the upper face of the cap.

Title: Valveless pump for pulps and thick liquids - using tank under suction, which is inadequate to draw pumped liquid back but draws liquid from supply
IPC: F04F3/00
Filed: 1974-07-08
Abstract: The pump delivering, e.g. high temp., highly corrosive liquids, consists of a closed tank under a low pressure, a supply line which leads from tank to supply, (the inlet opening of this supply line is submerged in the liquid to be pumped). The supply line is further so arranged that not all the fluid in tank can flow back through it under gravity. The pump further consists of an outlet line with an outlet opening which the liquid in the tank can flow under gravity. As the outlet pipe forms a U, a predetermined amout of liquid remains in the outlet. The suction required to draw this liquid back into the tank is larger than the suction which is required to draw liquid through the inlet pipe.

Title: Two-dimensional matrix switching logic - is employed in transmitting signals to liquid crystal digital indicator
Inventor: HEHLEN ROBERT
IPC: G09G3/18
Filed: 1975-01-17
Abstract: Switching circuits making use for example of MOS gates, are connected to four different supply voltage levels and to each column and line of a matrix. They are operated by signal pulses, clock pulses and inverted clock pulses, the frequency of the latter being some multiple of that of the signal pulses. An inverter and four OR gates in each circuit allow combination of operating pulses and corresponding output voltages to the matrix associated with pairs of values for S=0 or 1 in both the rows or columns of the matrix. Thus a control signals of S = 1 going to both switching circuits results in an output voltage amplitude of 3Vs at the corresponding intersection and a resulting energisation (Vs= trigger voltage) of the associated element.

Title: Electronic regulator for squirrel cage induction motors - permits variation of speed with torque equal to or greater than nominal torque using diodes and thyristors
IPC: H02P25/26
Filed: 1975-03-12
Abstract: The electronic regulator enables the motor speed to be controlled from zero up to a speed close to synchronising speed. The motor torque having values greater than normal. The rotor currents are supported via a mixed diode-thyristor bridge. The rotor currents being rectified in a controlled manner by this bridge and are then fed into a resistance. Each value of current corresponds to a given speed of rotation. A frequency reduction process of the thyristors firing pulses ensures a reduction in their angle of conduction, and thus reduces the rotor current. The result of which is a slowing down of the motor.

Title: False twist texturing spindle with friction discs - has stationary disk shafts and pivoting yarn guide threading automatically
Inventor: GLEYZE JEAN
IPC: D02G1/08
Filed: 1975-05-15
Abstract: Spindle comprises a base plate having an odd number of three or more sockets in which shafts carrying friction discs rotate on parallel axes. The sockets are positioned in sets of three at the corners of equilateral triangles, with the discs overlapping each other. A yarn guide tube extends just above the level of the base plate parallel to the shafts and the thread to be processed follows a zigzag path between the friction discs. For each group of three shafts there is a bracket in the shape of a "U", located outside the discs and able to pivot on an axis parallel to their axes. The upper limb of the "U" bracket has a yarn guide at its tip coaxial with the yarn guide tube below, to which the lower limb of the "U" is fixed. The "U" bracket can pivot between two positions. In the one, the axis of the two guides coincides with the centre of the triangle formed by the three sockets, whilst in the other, the guides are outside the sockets in the threading position. Design enables the yarn to be threaded through the discs much more quickly. The discs do not need to be stopped and there is no complicated equipment to open them. Their relative positions remain constant.

Title: Attachment of facing panels to building subframe - using tie rods at top anchored to plates cast into panels and frame
Inventor: SUCHET RAYMOND EMILE HENRY
IPC: E04B1/04
Filed: 1975-10-30
Abstract: Facing panels are attached to the sub-frame of a building by means of a mechanism which prevents the top of the panels from swinging outwards. The base of the panels are supported either on the panel immediately below or on the foundations of the building. The mechanism consists of a tie-rod (7), the ends of which are supported behind rigid plates (10,22) cast into both the inner top part of the panel and the outside of the frame. A small space (18,26) is left behind each plate to allow for the tightening of locking nuts (29,30) on the tie-rod by means of a key. A layer of material such as fibreglass can be placed between the panels and the sub-frame and this is compressed as the rods are tightened up, forming an insulation layer.
