Patent GB-2072532-A (GB)
Title: Stone crushing mill
IPC: B02C21/02
Filed: 1981-03-19
Abstract: A stone crushing mill comprising in particular stone crushing unit "a", feeder "b" and electrical drive system "c" is mounted on its own base frame unit "d". The whole is adapted to be carried on a multi- axled low trailer "f" and accordingly does not require its own wheel carriage, brakes, lights, blinkers etc. The crushing mill is thus transported to the required side where it can be lifted from the trailer, e.g. by means of hydraulic jacks inserted in pockets "i" in frame "d" and then base supports "e" are pivoted downwards towards the ground to support the mill in use. The low trailer may then be released for other use. <IMAGE>

Title: Device for loading or unloading a specimen of material under test, such as a settlement or consolidation test
IPC: G01N3/14
Filed: 1981-05-06
Abstract: Weights M1 - M6 are mutually suspended in a chain-like manner from a lever arm 1 which loads a specimen (not shown) by providing weights M2 - M6 with bolts 8 whose heads 9 extend into cavities 10 in the adjacent upper weight and are retained therein by conductive plates 11 closing the cavities. A platform 13 beneath the suspended weights M1 - M6 can be raised by a jack 14 under automatic control to support as many weights as desired so that only a prescribed number of weights e.g. M1-M3 is suspended from lever arm 1. Each bolt has an electrically conductive head 9 and a body surrounded by an insulating sleeve 16. Each plate 11 has upper and lower seats 18, 19 to make electrical contact with bolt head 9 and a conductive washer 17 respectively. As weight M2 is added to weight M1 bolt head 9 of weight M2 will engage plate 11 of weight M1 and momentarily close a circuit through the weights. The circuit will be opened as soon a weight M3 descends causing its washer 17 to disengage seat 19 of weight M2. <IMAGE>

Abstract: The shank (40) of drive pin (22) has a groove (52) near its head end which engages a reduced diameter bore portion (21) in the rivet (20) to temporarily hold them together prior to use. The drive pin (22) is inserted in the rivet bore (28) and drawn axially into the rivet bore (28) by a tool which causes the pin head (42) to engage the insertion end (39) of the rivet shank (24) and effect outward expansion of the rivet shank wall and which also causes break-off of the superfluous projection end (48) of the pin shank at a break-away indentation (46) formed in the pin shank. The pin shank (40) has serrations (50) which engage another reduced bore portion (32) in the rivet upon full pin insertion to hold the pin and rivet together permanently. This reduced bore portion (32) is serrated to enhance engagement with the serrations (50) of the pin (22). Both rivet body (20) and drive pin (22) are of plastics. <IMAGE>

Title: Release mechanism incorporating delay and interlocks
Inventor: SHIRLEY RICHARD
IPC: F42C15/18
Filed: 1984-12-18
Abstract: A release mechanism, for example a safety and arming unit for a weapon, includes a shutter 13 which is held against the force of a driving spring 22 at a first position spaced from a final or arming position for an actuator. Movement of the shutter 13 from the initial to the final position is prevented by an interlock 33,34 which is releasable only when the shutter 13 is rotated further away from the final position. The interlock is preferably released by means of an operating knob 16 having a cutout which obturates an over centre lever 41 for a detent. Movement of the shutter 13 away from the first position tensions the driving spring 22 and upon release of the detent the spring 22 drives the shutter 13 towards the armed position, under the control of escapements 27,28 which are coupled to the shutter 13 by a unidirectional drive coupling 29,30. The operating knob 16 is arranged to interlock with a cover 2 to provide effectively a second detent for the shutter 13. <IMAGE>

Abstract: An aeration tank, particularly for use in the treatment of sewage liquor, trade effluent and the like, comprises a chamber (6), generally oval in plan, to provide a continuous flow path F, inlet and outlets pipes (10, 12) being provided in conventional manner. Extending across the flow path is impeller means in the form of a rotor (14) on which paddles (16) are mounted. Downstream of the impeller and extending across the flow path is a deflector means afforded by a baffle (18). The baffle extends from a level adjacent to, preferably above, the surface of the liquor in the tank to a level below the surface of the liquor, and is inclined so as to cause liquor impeller by said impeller means, and air entrapped in the liquor, to be deflected towards the bottom of the tank. In this manner a high oxygen input may be obtained with a relatively low power input. <IMAGE>

Title: Measuring characteristics of transistors or diodes
Inventor: SAKAI RYOICHI
IPC: G01R31/26
Filed: 1985-09-11
Abstract: An electronic device measurement apparatus measures a characteristic of an electronic device under test (DUT) by applying a sine- wave voltage to the DUT, detecting a voltage across the DUT and a current flowing through the DUT and displaying a characteristic curve in accordance with the detected voltage and current. Since the sine-wave voltage is generated in synchronism with an AC line voltage and an amplitude thereof is independent of the line voltage, each of circuits in the measurement apparatus is not affected by variation of the phase and amplitude of the line voltage. Moreover, the sine-wave voltage is symmetrical, so that a display distortion can be eliminated. The sine wave is produced by use of a pulse generator 42,44,46 synchronised to the line voltage, phase comparator 48, VCO 50, frequency divider 52, logic gaes 54-60, multiplexer 62, Miller integrator 64-82, peak amplitude detector 86-92 and an amplitude stabilising loop 94-106. <IMAGE>
