Patent GB-2133127-A (GB)
Title: Improvements in a process of manufacturing cement
Inventor: DAVIES P
IPC: C04B7/47
Filed: 1983-12-20
Abstract: Cement manufacturing plant in which a mill 2 feeds limestone to a kiln 6 discharging to a recuperator 8. Clinker from the recuperator passes through a roller crusher 10 and carried in a bucket transporter 12 to an indirect heat exchanger 14. Hot air from the recuperator 8 is used for heating and drying the raw limestone, as combustion air, or recycled to the recuperator. The roller crusher 10 and the indirect heat exchanger 14 are able to accept clinker at temperatures up to 1000 DEG C, and thereby accommodate sudden surge discharges of clinker from the kiln without the need to provide for air supplies and atmospheric venting facilities in excess of that required for normal operation. <IMAGE>
Patent GB-2157432-A (GB)
Title: Thermostatic controls
Inventor: CLIFF THOMAS CHARLES
IPC: F23N3/04
Filed: 1984-04-10
Abstract: A thermostatic actuator for a damper valve in the air inlet to a boiler is operated by one end of a long lever (11) supported on a manually-rotatable shaft (21) which allows allowing it freedom to swing in arc A B and also to be moved bodily along the shaft. Cam (24) rotatable with shaft (21) urges the lever along the shaft. The first part of this movement adjusts the position of the lever relative to a thermal system (14, 16, 18) so as to alter the operating temperature. The second part of this movement removes the lever from contact with the thermal system and into contact with stop (30). Further rotation of cam (24) causes lever (11) to pivot about stop (30) and thus opens or closes the valve under manual control by rotation of shaft (21). To provide manual over-ride control for a lever (11) actuated by temperature responsive means (14, 16, 18) the lever is mounted on a manually rotatable shaft (21) in a manner which allows it to pivot in arc AB and to move along the rod. The rod carries a cam (24) which initially moves the rod to adjust the null position of the rod. Further movement of the cam causes the rod to abut a stop (30) and to be rotated about the stop by the cam. The lever operates a damper valve in a boiler air inlet. <IMAGE>

Patent GB-2155085-A (GB)
Title: Girder arch and the like securing member
Inventor: THACKRAY ROBERT
IPC: E01B11/08
Filed: 1985-02-06
Abstract: The invention relates to the securing of girders or arches, or of railway rails. Conventionally, such members are held in abutting relationship by so-called fishplates, traditionally formed by rolling. Rolled fishplates are of adequate strength but are heavy and relatively expensive to produce. The objective of the invention is to provide a fish plate of comparable strength but of lighter weight and lower cost. The objective is met by a construction comprising a pressing of an appropriate metal, said pressing having a corresponding profiled shape to each side. Thus, by being of pressed, e.g., W-cross-section, high strength and low weight is achieved and the production route is less expensive than rolling <IMAGE>

Title: Process for the production of a grenade body
Inventor: ASSMANN HANS
IPC: F42B12/32
Filed: 1985-08-22
Abstract: In the production of a grenade body, the fragmentation casing 1 is but up in a step-wise manner by producing a receiving portion 15 which has a large opening (5), through which the explosive filling (2) is then introduced, and completing the fragmentation casing by means of a completing portion 8 whilst leaving a fuse tube opening (3). A plastics sheathing 7 may already be applied to the receiving portion 15 if the latter represents a substantial part of the fragmentation casing 1 and the completing portion (8) represents a closure plug for the opening (5). However, the plastics sheathing 7 may also be injected moulded around the fragmentation casing, as a final step, the fragmentation casing forming a heat- insulating cover for the explosive (2). In this alternative form of the process, the receiving portion 15 and the completing portion 8 are substantially identical half shell members which are fitted around a preformed explosive filling (2). <IMAGE>
Patent GB-2165693-A (GB)
Title: Method and apparatus for loading information into an integrated circuit semiconductor device
Inventor: ULLMANN JERZY JOSEF
IPC: G11C7/00
Filed: 1985-09-09
Abstract: An arrangement for loading information into an integrated circuit semiconductor device (10) comprises a mask (14) having a plurality of regions which may be more transmissive or less transmissive to radiation (12), to form a state pattern. The device (10) may be a memory or an array of logic gates, having a plurality of regions sensitive to radiation to control the state of semiconductor elements of the device. Selective irradiation of the radiation sensitive regions via the mask enables the state pattern to be loaded into the device. The mask may be carried separately from the device, so that it can be replaced by a further mask carrying a different state pattern, in which case there are alignment means, e.g. optical gratings (18, 20) for generating Moire fringes, to align each mask with the device. Alternatively the mask may be bonded to or integrated on the surface of the device. As an alternative to the mask being replaceable, it may have regions which are alterable so as to be more or less transmissive to radiation so that the state pattern carried by the mask can be changed. The arrangements enable very fast loading of data into VLSI or WSI integrated circuit devices to be effected.

Patent GB-2188216-A (GB)
Title: Ring bus communications systems
Inventor: PARKER GUY MARTIN
IPC: H04L12/433
Filed: 1986-03-17
Abstract: To reduce bus latency in token-passing ring bus communications systems shift register buffers (14, 15) in each station (1, 2, 3) are provided with a switched output (16). A controller interface (13) on detecting from a single bit in a token that the ring bus (4) is occupied causes the switch (16) to select a shift register output (14) representing only a single bit delay in each station 1, 2, 3. In an alternative method of operation (figures) a multiple output shift register is used so that if the controller interface determines from other fields that capture of the token by its associated station is not permissible switching may be effected to introduce the minimum bit delay compatible with such determination. <IMAGE>

Title: PAL coders and decoders
Inventor: CLARKE CHRISTOPHER KEITH PERRY
IPC: H04N11/16
Filed: 1986-04-08
Abstract: PAL chrominance and luminance decoder circuits are based on transversal filters and for any given line (line zero) accept contributions from at least seven different lines taken from at least three consecutive fields. In the chrominance decoder circuit based on Figure 5 the sum of the weighting factors applied to the components on 'even' numbered lines equals that for 'odd' numbered lines. In the luminance decoder circuit based on Figure 9 the weighting factors for line zero, less unity, and for the other 'even' lines together equal the sum of the weighting factors for the 'odd' lines. The weighting factors are conveniently related by factors of 2 or 4. The decoder circuits may be used to form a composite decoder (Figure 12) with some components being shared in common. The filter circuit can be embodied in a PAL coder to reduce cross effects. <IMAGE>
