Title: Formed Bodies of Alkali Metal Hydroxides
IPC: C01D1/44
Filed: 1979-08-06
Abstract: Sodium or potassium hydroxide monohydrate in compacted form is obtained in a process in which crystallised alkali metal hydroxide monohydrate is separated off from mother liquors, washed and compacted to give solid formed bodies. Sodium hydroxide monohydrate crystals suitable for compacting are produced in a process wherein a cold, saturated and a hot solution of sodium hydroxide are brought together, the amount, concentration and/or temperature of the two solutions being so coordinated with one another that the temperature of the mixture is one at which a supersaturated solution is obtained containing sodium hydroxide monohydrate crystals, which are separated off.

Title: Improvements in or relating to temperature control of sensing devices
IPC: C03B25/06
Filed: 1979-08-23
Abstract: The temperature of a device is controlled at a value different from that of its environment, about which it can move, by feeding heating or cooling fluid to the device along paths such that the total length of inlet path or paths remains constant as the device moves. The device 6 is preferably a measuring device measuring the temperature distribution of glass 4 in an annealing lehr 2. The device radiation pyrometer (6) is mounted for reciprocable movement along the guide rail (10). It is housed in a cooling jacket (12) through which cooling water from inlet pipes (18,20) flows, the pipes (18,20) extending through a respective one of the side walls (3) and being wound around a respective rotatable reel (26,28). The reels (26, 28) are rotated in synchronism to reciprocate the pyrometer (6) and to keep the total length of the inlet pipes (18,20) within the lehr constant. By maintaining the same constant water flow rate in each of the inlet pipes (18,20) the temperature of the radiation pyrometer (6) is kept substantially constant. <IMAGE>

Title: Vehicle suspension element
Inventor: RIACH ALAN BRYSON
IPC: B60G11/12
Filed: 1981-12-30
Abstract: A semi-elliptic leaf spring 1 is connected to a vehicle frame member 3, at one end, pivotally to a bracket 2, and at the other end by means of a shackle 9 and a bracket 10. The shackle 9 is hung from the leafspring and carries the bracket 10 by means of bolts 11. The shackle is made of a continuous band of material which can be resiliently deformed in cross-section: it consists of a core of cords and a surrounding sheath of rubber or plastics material. The bracket has a stop surface 10 to restrain the leaf spring if the connection to the bracket 2 fails, lateral surfaces 10e to restrain the adjacent part of the leaf spring against sideways movement and a rebound surface 10d. The suspension element has the advantage of a conventional shackle, and resiliently deformable components, while not being unduly costly.   <IMAGE>

Title: Article detecting device in wrapping machines
IPC: B65B57/10
Filed: 1982-05-06
Abstract: In prior art detecting devices (eg. GB 2046695), comprising feelers mounted on an actuator wheel, cams and cam followers, if two or more successive articles are absent from a wrapping head, wrapping material may be partially fed because of the dwell time of the cams between one detection sequence and the next. The instant device obviates this problem by providing two actuator wheels (5, 6) on a common shaft (4) which alternately detect the presence, or absence, of articles by feelers (7, 8) and separately dis-engage feed rollers (2, 3) via levers (13a 14a), the dwell time of one wheel being out of phase from the other so that the feed rollers only engage if there is an article present. <IMAGE>

Title: Adjustable cutter for a rotary tool
IPC: B23B29/034
Filed: 1982-05-20
Abstract: The adjustable cutter has a body (10) with a screw threaded portion (12) mounting an internally screw threaded adjustment ring (16), a disc spring (18) and a tapered collet (20) having a frusto conical surface (22). The surface (22) is engaged against a frusto conical recess (62) in a tool holder (56). The body (10) is adjustable axially of the tool holder by rotation of the ring (16) and then clamped in position by bolt (14). A key (30) engaged in a keyway (70) prevents rotation of the body relative to the tool holder. The adjustable cutter is thus lockable relative to the tool holder firmly and accurately. <IMAGE>
Patent GB-2128456-A (GB)
Title: Improvements in or relating to data transmission and receiving systems
Inventor: DIKSHIT SUDHIR SHARAN
IPC: H04B3/04
Filed: 1982-10-01
Abstract: A data transmission and receiving system employs an arrangement for rapidly setting up a receiver equaliser to conform with the response characteristics of the transmission channel. The arrangement utilizes correlation (14) and corrective circuits (15) in the receiver (11) which serve to set the equalization circuits (not shown) in accordance with the channel response. Prior to the transmission of normal data a test pattern signal with a short second segment representing a leaning pattern of pseudo-random digital pulses is transmitted, stored at the receiver, and correlated (14) with a fixed training pattern to produce an estimate of the channel response. If the channel is reasonably good or setting up time is restricted this response may be used to set the equaliser. Otherwise the response is corrected (15) to produce a more accurate representation of the channel response before being used to set the equaliser. The first segment of the learning pattern is used to set the receiver a.g.c. and timing circuits. <IMAGE>

Region 9 of the cylinder acts as a guide surface for tail 4. Tail plates 22, 23 are movable together with main bolt 8 by the engagement of their slots 26, with projections 21 on bolt-tail 4. These tail plates bear head- and foot-bolts for the door. <IMAGE>

Filed: 1984-07-10
Abstract: A lever (10 to 12) pivoted to a single handle means (5) forms part of a toggle linkage (9 to 13) for pressing a cutting knife (7) towards a drive wheel (6) so as to pierce a cylindrical part (1) of a can (2) to be opened below the lid (3) of the can (2). An upstanding rim (4) of the can (2), by which the lid (3) is attached to the cylindrical part (1), is clamped between the drive wheel (6) and a resilient disc (31) immediately above the cutting knife (7). On rotation of the drive wheel (6) by means of a ratchet drive, including ratchet handle (16), the drive wheel (6) moves around the rim (4) so as to cause relative movement between the cutting knife (7) and the cylindrical part (1) of the can (2) and thereby sever the lid (3) from the cylindrical part (1). To withdraw the cutting knife (7) from the drive wheel (6), an extension (12) on the lever (10 to 12) is pressed into a recess (14) in the handle (5) so as to retract a connecting link (9) and thereby permit return springs (29) to move a slide (8) carrying the cutting knife (7). The slide (8) may move along a rectilinear path extending parallel to the longitudinal axis of the handle (15), or the slide may be sector shaped and mounted for oscillation in an arcuate slot in the handle about an axis parallel to the axis of the drive wheel. The cutting knife may be circular or pointed. <IMAGE>
