Title: Wall plugs
Inventor: SILVERMAN GEOFFREY MAYER
IPC: F16B13/14
Filed: 1988-07-25
Abstract: A method of forming a wall plug in a hole 11 provided in a wall 12, involves ejecting a plastics material 13 from a discharged nozzle 10 into the hole 11, which plastics material foams in order to fill the hole 11. The plastics material 13 cures to form a composition into which, for example, a wood screw may be securely held.

Patent GB-2228068-A (GB)
Title: Hot water supply by remote control
Inventor: HUNNIBAL ARTHUR STANLEY
IPC: F24D19/10
Filed: 1989-11-02
Abstract: Water supply to a basin, bath or sink is designed to provide water at that point of use at the desired temperature without any wastage. Hot and cold water is fed to a thermostatically set mixer tap 1, hot and cold supplies being separated by the use of a plunger control 14 in the centre of the knob for cold only. The outer rim of the knob is rotated for hot water; cold is blended at the thermostat to achieve the pre-set temperature. Hot, pressurised water arrives at the thermostat at cylinder temperature via a previously empty feed pipe 2, this water being pumped from the cylinder 11 into a chamber 10 housed in the top of the cylinder. The first 5 degrees of turn of the tap trips a switch operating a slide valve 13 to close the waste. The next 5 degrees movement sends a radio signal to open a valve 6 which in turn operates the pump 7. The last 5 degree turn enables switch 3 and sends a similar signal to close the valve, which in turn deactivates the pump. Returning the tap to zero re-sets switches 3 and 2 and trips the slide valve switch in reverse to release the slide valve over the waste, to empty the water. <IMAGE>

Title: Waterproofing of tunnel lining
Inventor: MITCHELL SAMUEL BAILEY HART
IPC: E21D11/38
Filed: 1990-03-16
Abstract: This disclosure relates to a arcuate precast concrete tunnel lining segment (10) having end faces (11) and circumferentially extending side faces (12). The end faces (11) have relatively shallow grooves (13) in which relatively thin sealing strips formed from a water swellable material, such as hydrophilic rubber (14), are mounted to project from the faces for sealing engagement with adjacent corresponding faces of other segments. The circumferentially extending side faces (12) of the segment are formed with slightly deeper grooves (15) containing correspondingly thicker gaskets formed from a rubber or neoprene (16) to project further from the side faces and to seal with corresponding faces of adjacent segments. The thicker gaskets (16) projecting further from the side faces allow a greater tolerance at the circle joints of the segments to accommodate ground movement and building tolerances. <IMAGE>

Patent GB-2253974-A (GB)
Title: Convolutional coding
Inventor: LLOYD BARRY GEORGE WILLIAM
IPC: H03M13/33
Filed: 1991-03-22
Abstract: A sequence of input bits to be coded is terminated by a group of four zeros (in 103) prior to coding by a 16-state convolutional coder 104 using a systematic code. The input bits and the coded bits P from the coder 104 are formatted (105, 106, 109) into an output sequence for transmission. The terminating zero bits are not transmitted but are reinserted at the receiver. An alternative receiver (Fig. 9) for receiving a conventional transmission receives the terminating bits but discards them in favour of locally generated zeros thereby correcting any transmission errors. A receiving soft decision decoder can ascribe maximum confidence to the reinserted bits. <IMAGE>

Title: Micropropagration
Inventor: MCFARLANE NIGEL JAMES BRUCE
IPC: A01H4/00
Filed: 1991-07-26
Abstract: A method of locating a stem of a plant during micropropagation comprises the steps of generating an image signal by a video camera representing an image of the plants, and processing the image signal to locate portions of the plants having widths and lengths likely to constitute stem portions. Stems are then selected by choosing plant portions fulfilling the criteria that the angle to the vertical of the most nearly vertical side of the plant portion is less than a predetermined angle, and that there can be traced from the bottom of the plant portion a continuous downward path through plant material to the surface of the material in which the plant is growing. Another criterion which can be used is that the plant portion terminates at its top and at its bottom in an area of plant material greater than various predetermined size criteria. The location signals are then processed to provide a control signal for controlling a robotic end effecter to move to the required location, to grasp the selected stem, and to remove the plant or a required portion thereof from a nutrient medium in which the plant is growing. Stereo information can be derived by observing the plant from slightly different directions.

Patent GB-914013-A (GB)
Abstract: 914,013. Valves. HARPER-WYMAN CO. Dec. 17, 1959 [Aug. 13, 1959], No. 42957/59. Class 135. A gas-flow control valve comprises a body having an inlet and an outlet with a thermostatically actuated valve in series with a manually rotatable disc valve between the inlet and the outlet, the rotation of the disc valve being arranged to alter the setting of the thermostatically actuated valve, the device being characterized in that ports controlled by the disc valve permit a first and lower maximum rate of flow in a first range of movement of this valve corresponding to a lower operating temperature range of the thermostatically actuated valve and a higher rate of flow in a second range of movement of the disc valve corresponding to a higher operating temperature range of the thermostaticallyactuated valve. As shown, communication between the inlet 122 and the outlet 56 in the body 20 is controlled by the manually-rotatable disc valve 28 in series with the thermostaticallyactuated valve 24, the disc 28 being coupled to a yoke 114 carried by a spindle 94 which is rotatable by the hand control knob 30. An axially movable screwed spindle 46 is in driven engagement with the rotatable spindle 94 through a pin-and-slot connection 100, 102 and engages a lever 40 acting on the thermostatically-controlled valve member 36 to alter its setting by rotation of the hand knob 30. The thermostatic control of the valve member 36 takes place through a motor capsule 50 coupled to a thermal element (not shown) through a pipe 52, the capsule providing a movable fulcrum for the lever 40. This lever is a bimetallic element to compensate for temperature variation of the gas flow. The screwed seat 32 of the thermostatic valve is adjustable by a calibrating pin 34. The disc 28 has an arcuate port 132 comprising a wider portion 132A and a narrower portion 132B co-operating with ports in the body comprising a kidneyshaped inlet port 120, an outlet port 124 leading through the thermostatically-controlled valve to a main outlet chamber 22 and a port 126 having an arcuate extension 126A, the ports 126 and 124 being connected through a restricted orifice 134. The " off " position of the device (Fig. 6) is indicated by a radial boss 72 on the hand knob 30 when it is under an indicating dot 73 on a fixed bezel 70 (Fig. 2). On anticlockwise rotation of the knob 30 to the " on " position the narrower portion 132B of the port 132 registers with the extension 126A of port 126 (Fig. 7), so as to supply gas, e.g. to a pilot burner through a passage 128A and an adjustable restrictor 130, and at the same time supply gas to the thermostatic valve and outlet 56 through the port 124 up to a lower maximum rate of flow determined by the orifice 134 and corresponding to a lower range of operating temperatures. Further rotation of the knob 30 brings the wider portion 132A of port 132 directly into register with the port 124 (Fig. 8), so as to supply gas through the thermostatic valve 6 outlet 56 up to a higher maximum limited only by the opening of this outlet and corresponding to the higher operating temperature range.
