Patent GB-2013353-A (GB)
Title: Camera focus control system
IPC: G02B7/32
Filed: 1978-12-18
Abstract: A focus control system in a photographic camera, for example, includes a rangefinder (14) (preferably acoustic) and driving means (38) responsive to a signal from the rangefinder for moving a movable element of a variable focus lens to a focused position. In addition to being movable throughout a first region in which it focuses at an image plane images of objects within a given range, the lens is also movable in a second region which is outside its focusing region. Prior to an automatic focusing operation, the lens is always returned to this second region, so that automatic focusing movement is unidirectional and always starts from the same reference point. The return movement of the lens to the reference point may be a part of an automobile focusing and exposure cycle, in a camera. Where provision is made for manually focusing the lens, as an alternative to automatic focusing, means may be provided for automatically returning the lens to its reference point after a manual exposure cycle in the camera. <IMAGE>

Title: Separating lead particles from exhaust gases
IPC: F01N3/021
Filed: 1978-12-20
Abstract: Lead particles in the exhaust gases of an internal combustion engine are agglomerated in packings of wire mesh or expanded metal which are contained in spaces defined within an elliptical section casing (1) between the casing wall and a perforated pipe (17) extending between perforated transversely extending walls 5 and 6. Inlet pipe 14 leads into an inlet chamber 12 defined by a perforated tubular wall 13 attached to transverse wall 5, porous packing filling the annular gap between the casing and the wall 13. Gas passes either through holes 16 in wall 5 or through holes 23 in pipe 17 into the packing 19, purified gas leaving the packing through holes 21 either directly into outlet pipe 22 or via outlet chamber 9 and apertures 23. External ribs on the casing help cool the device and so enhance particle agglomeration. The device functions also as an exhaust silencer. <IMAGE>

Patent GB-2048398-A (GB)
Title: Torque limiting device
IPC: F16D7/02
Filed: 1979-05-08
Abstract: A torque limiting device of simple 3-piece construction reliably automatically disengages driving and driven members when the latter is subjected to a predetermined overload. The device comprises a pair of co-operating coupling members (12, 10) which respectively engage the driving and driven members, and a helical compression spring (14) interengaging the two coupling members. The direction of lay of the spring (14) is selected in accordance with the direction of rotation of the shaft (30). Overloading the driven member increases the diameter of the spring which causes it to disengage itself from the driving coupling member (12) to thus prevent torque from being transmitted to the driven member (10) while overloaded. <IMAGE>

Title: Chucking reamer
IPC: B23D77/04
Filed: 1980-05-07
Abstract: A chucking reamer has a flattened section on its head, with a crescent-shaped recess 19. A crescent-shaped body 64 integral with a cutter device 67 is held in the recess by a fixing screw 36 and a pair of headless screws 49, 58 are threaded into the head to adjust, via thrust pieces 73, 74, the position of the crescent-shaped body and the cutting device on base surfaces 24, 28 either side of the recess. The fixing screw has a conical head 37 which fits into a conical recess 78 in the body. An inner threaded hole is provided through the head, running perpendicularly from the bottom recess face, for receiving the screw. The longitudinal axis 34 of this threaded hole is lower than the longitudinal axis 81 of the conical recess, so that when the body is to be moved to the smallest radius position, the fixing screw experiences a bending stress, which pulls the body towards the curved walls of the crescent- shaped recess. <IMAGE>

Title: Plate heat exchanger
IPC: F28F27/02
Filed: 1980-05-28
Abstract: In a stacked-plate heat exchanger wherein the ducts 1, 4 conveying fluid to and from the plate interspaces 3 are formed by aligned holes in the plates, and wherein said fluid is supplied at one end of the plate pack to the inlet duct 1 and discharged at the other end of the pack from the outlet duct 4, providing a fluid flow path of asymmetric or Z form through tie pack, maldistribution of said fluid tending to give rise to partial starvation of the flow spaces 3 nearer the inlet end of the pack is overcome by the provision in the inlet duct 1 of a flow distributor insert 9 intended to encourage flow into the flow spaces 3 nearer said inlet end, and to inhibit flow into those flow spaces 3 remote from the inlet end. A collector 20 may be provided in the discharge duct 4 and is intended to increase the local flow velocity near the inlet end to reduce the pressure gradient due to the momentum effect. <IMAGE>
Patent GB-2059454-A (GB)
Title: Apparatus for removing an irregularity in a thread
IPC: D01H13/22
Filed: 1980-09-29
Abstract: In a process for effecting a thread join in an open-end spinning machine the thread, in which a join has been spun and which is drawn off from the spinning apparatus, continues to be discharged, the take-up bobbin being stationary until the thread section with the defect is severed in the course of a thread attachment process, whereupon the thread drawn out of the spinning apparatus is wound onto the take-up bobbin. On the appearance of a defect in the thread, the take-up of the latter on to the bobbin is discontinued, and the thread is then discharged in the above- described way. For this purpose the air throughput of a source of low pressure connected to ducts 22, 31 and 41 is controllable and, when the open-end spinning apparatus comes into operation, can be temporarily increased beyond the air throughput required during a normal spinning process. <IMAGE>

Title: Agglomerating perlite ore fines prior to expansion
IPC: C04B14/18
Filed: 1981-07-16
Abstract: Perlite ore fines (at least 50% of the particles being not greater than 74 mu ) are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines, e.g. orthoboric acid or metaboric acid. The perlite ore fines and agglomerating agent are mixed, preferably by dry mixing, and then heated to the temperature of the viscous liquid phase and held at that temperature for a short period while the liquid coats at least a portion of the perlite ore fines and effects agglomeration. Thereafter, the agglomerated perlite ore fines can be expanded in a conventional perlite ore expander. The resulting expanded materials have properties essentially identical to standard expanded perlite ore and are useful for such purposes as insulating fillers and light weight aggregates.
