Patent GB-2035270-A (GB)
Title: Apparatus for conveying and aligning stacked sheets
IPC: B42C19/08
Filed: 1979-11-09
Abstract: In apparatus for conveying successive stacks 15 of sheets, e.g. to stations at which binding operations are to be performed on the stacks, the stacks are advanced by pushing elements (14) to each station, at which a resiliently yieldable finger (17) projects through a slot (16) in the conveyor track. The finger (17) aligns the leading edges of the sheets in the stack. When the stack of sheets is further advanced, the upper inclined edge of the finger engages the bottom rear corner of the slot (16) causing the finger to sink below the track until a slide upon which the finger is pivotably mounted is returned in time for the alignment of the next stack. <IMAGE>

Title: A hair curler
IPC: A45D2/00
Filed: 1980-01-31
Abstract: The hair curler consists of a cage-like element having a spheroidal shape divided into two hemispheres 1, 2 which are connected together by means of an inner core 6 so that they are capable of relative rotation. One hemisphere 1 is provided in its polar zone with a hairpin 9 for elastically clamping the base portion of a hair lock, and the two hemispheres present an opening into which the lock is inserted. A hair lock retainer 5 is provided in the opening so that the inserted and clamped hair lock cannot escape. When one hemisphere is rotated in the desired direction, the lock is wound onto the axial core 6 and is progressively drawn into an annular chamber 3. The curler may alternatively be cylindrical etc. <IMAGE>

Title: Mobile crane
IPC: B66C23/42
Filed: 1980-02-04
Abstract: A mobile crane comprises a luffing jib (17) mounted on an upper chassis (16) and the upper chassis (16) is mounted by a rotatable connection (15), which allows sewing, on an intermediate frame (12) instead of being mounted directly on a carriage (10) as is conventional. The frame (12) is longitudinally slidable by means of guides (13) on the carriage (10) between a forward travelling position as shown in the drawing, in which the weight of the crane as a whole is uniformly distributed over the various wheels (11) of the carriage (10) to give a minimum axle loading while travelling, and one of a number of rearward lifting positions in which the centre of gravity S2 of the upper chassis and the parts which it carries is rearwardly displaced for load counterbalancing purposes. Fixing elements (14) detachably lock the intermediate frame (12) in its various positions on the carriage (10) and can be automatically disengaged when a drive (not shown) to slide the frame (12) along the carriage (10) is actuated. <IMAGE>

Title: Pneumatic classification of finely-divided solids
IPC: B07B9/02
Filed: 1980-07-04
Abstract: The classification is performed by circulating solid particles within the main body of the classifier housing 1 (Fig. 1). To improve the classification, the circulation is increased by cutting a portion of the coarse product stream separating in the lower section of the housing to pass upwards and around and along the inner periphery of the housing by means of the gas medium in circulation within the housing. This is accomplished by means of curved stationary flanges (41) attached to the inside front and back walls of the lower part or collecting hopper (4) of the classifier.

Patent GB-2088483-A (GB)
Title: Waste liquid collection apparatus
IPC: A47L11/40
Filed: 1980-10-14
Abstract: An apparatus for the collection of waste liquid materials comprises an exhauster adapted to draw waste liquid materials into a closed reservoir 12. In order to prevent waste liquid materials in the reservoir 12 from entering the exhauster, the exhauster draws air from the reservoir 12 via a centrifugal impeller 40 which, whilst allowing air to enter, throws away centrifugally any liquid which comes into contact therewith should the liquid level in the reservoir become too high. The increased power requirement to drive the impeller 40 which occurs when the impeller contacts liquid in the reservoir can be used to close a valve in the exhauster inlet line to assist in preventing liquid entering the exhauster. <IMAGE>

Abstract: A hand machine tool provided with an air-spring percussion mechanism is proposed in which the guide cylinder (2), the piston (23) and the gudgeon pin (26) are made of elastic plastics material similar in kind at least as regards their heat expansion, especially a polyamide. Due to the use of the said material, which is preferably reinforced with glass fibres, and due to the particular formation of the components referred to matching the properties of the material, a better efficiency, a quieter vibration free running and a more comfortable handling is achieved due to lower heating of the external housing portions and a better protection for the components of the hand machine tool is also achieved. <IMAGE>

Title: Conductive polymer ptc circuit protection devices
IPC: H01C7/02
Filed: 1981-04-21
Abstract: Circuit protection devices which comprise two columnar electrodes and a conductive polymer element, at least a part of which is a PTC element. The device is so constructed that if a hot zone forms in the PTC element when current is passed through the device, it forms at a location away from the electrodes, thus increasing the useful life of the device. In one preferred embodiment, the conductive polymer element has an intermediate portion of increased resistance, thus causing the hot zone to be located at or near the intermediate portion. The intermediate portion may be of reduced size and/or be composed of conductive polymer of relatively high resistivity.

Title: Gyro Damping Apparatus
IPC: G01C19/04
Filed: 1981-08-14
Abstract: A two-axes dynamically-tuned displacement gyro (30) is mounted in gimbals to pivot about mutually perpendicular x and y axes, and the gyro rotor spins about a Z axis. Movements of the gyro housing (44) relative to inertial space are measured by pick-offs (54A, 54B). Torquers (56A, 56B) are arranged on the x and y axes, respectively. Known types of such gyros may suffer from nutation oscillation which causes them to drift further and further from their correct attitude.   The present invention damps such oscillation by providing a differentiating circuit between the x- axis pick-off and the x-axis torquer. <IMAGE>

Title: Solenoid having spring biased lost motion link
Inventor: PORTSCHELLER JAMES I
IPC: H01F7/16
Filed: 1981-08-21
Abstract: The present invention overcomes the disadvantages of prior art solenoids to develop adequate initial pulling force for a given coil size. The solenoid having a linear pull stroke includes a coil operated plunger (16) having a lost motion coupling (20, 28, 32, 38, 40) adapted to be connected with a load in order to allow the plunger (16) to retract a predefined distance during the initial part of the stroke thereby to develop a higher level of pulling force before substantial force is actually imparted to the load. The plunger (16) comprises an elongate body (18) having a piston-like link (28) slidably mounted in a cavity (20) at one end of the body (18) and adapted to be coupled with the load. A spring (36) trapped between the link (28) and the body (18) resets the link (28) relative to the body (18) before the pull stroke is completed.
