Title: Settling tank with by-pass
Inventor: COCHRANE ARTHUR
IPC: B01D17/02
Filed: 1982-09-17
Abstract: A settling chamber 14 separates oil from drainage water which enters the chamber through inlet 20 and leaves through downpipe 26, but should flooding increase the flow rate then the level in upstream chamber 12 rises, so that most of the water flows over the upturned rim of pipe 32 and bypasses chamber 14. Accumulated oil 22 is periodically removed from chamber 14. In another construction, the settling chamber is annular and encloses the upstream chamber, and in a third construction the upstream chamber and bypass are replaced by a single wide-bore pipe arranged at a higher level than the inlet to the settling chamber. <IMAGE>

Title: Spectroscopic analysis
Inventor: STEPHENS NOEL WILLIAM FRANK
IPC: G02B5/30
Filed: 1982-09-23
Abstract: A birefringent variable-retardation device comprises a fixed inclined plate 40 of positive birefringence material, a fixed plate 42 of negative birefringence inclined oppositely, and a pair of plates 44, 45 also inclined in opposed directions and of positive and negative birefringence material respectively. The plates 44, 45 are rotatable about an axis 46 to vary the retardation imposed by the device upon a beam 4 of radiation. The device may be used in a birefringent Fourier transform spectrometer where it may be replaced by a device having one fixed, inclined birefringent plate and one rotatable plate (28 in Fig. 3 - not shown). The rotating plate devices may also be replaced by a liquid crystal device (50 in Fig. 5 - not shown). <IMAGE>

Title: Identification cards
Inventor: SMALL EDWARD A
IPC: B42D25/45
Filed: 1982-11-23
Abstract: This invention relates to a plastic identification card. A magnetic encoding panel is printed, preferably by screen printing. This enables the magnetic encoding panel to be applied more economically than with conventional magnetic tapes. The printing of the magnetic encoding panel is applied to a drop out area in the transparent protecting coating, followed by polishing both of the protective coating and the printed magnetic encoding panel. This greatly increases the passes through a reader prior to failure of the magnetic encoding panel.
Patent GB-2114546-A (GB)
Title: Sheet feeding device
Inventor: DE SIMONE PANTALEO
IPC: B65H3/02
Filed: 1982-12-08
Abstract: A shaft (10) with flap (12) rotates in the direction of arrow (11) each time a sheet is to be fed. A stripper element in the form of a resiliently flexible flap (12) bearing a high friction layer (31) wipes against the top sheet (24) of a stack (26) to initiate sliding of the top sheet off the stack. The sheet advances in the direction of arrow (32) between the flap (12) and a reject roller (34) which rotates in the same direction as the flap (12) and shaft (10). The coefficients of friction of the flap (12) and reject roller (34) are chosen so that if two sheets are fed, the lower one is returned to the stack by the reject roller (34). The use of such a flap to separate sheets ensures that the sheets are fed without damage or marking. <IMAGE>

Title: Control of hydraulic booms
Inventor: ZOLLMAN PETER MARTIN
IPC: E21D9/10
Filed: 1983-06-02
Abstract: Automatic electronic control means are for the movement of hydraulic boom(s) or e.g. in tunnel- boring and road-header machines.

Filed: 1983-07-26
Abstract: A flying machine in the form of a bicycle or tricycle frame (10) which can be propelled in flight by human propulsion using pedals (16) and steered in flight using handle bars (12). A pair of movable wings are in two parts, an inner tiltable section (27) and a movable outer section (29), so that not only does each complete wing flap from the root, the inner section (27) tilts up and down the outer section (29) folds backwards and forwards to simulate the wing rhythm of a gull in level flight. The wings are driven by means of a cranked sator spar (82) one end of which performs circular motion which is translated into the wing movements, whilst the other end is coupled to the sun wheel (68) of a sun and planet gear mechanism (66). A spring rotor (78) is driven by an outer wheel (70) of the sun and planet gear mechanism and is wound up by the pedals and places a restoring force on the outer wheel of the gear mechanism. Rear wheels 22 can be retracted when air borne. <IMAGE>

Title: Method and apparatus for determining applied stress
Inventor: OWENS ALAN
IPC: G01L1/22
Filed: 1984-05-03
Abstract: A method and apparatus are provided for continuously determining and monitoring an induced dynamic stress field at a location on or in a structure, in which multiple strain gauge elements, suitably in the form of a rosette, are provided at the location. Sequences of electrical input signals (e.g. voltages or currents) are received at input means, these signals being derived from the elements and proportional to induced strains in the structure. Arithmetic and logic means are connected to the input means and operate on the sequences of input signals to derive sequences of electrical output signals (voltages or currents) proportional to stress field parameters at the location, e.g. maximum and minimum principal stresses and an angle identifying the direction of one of the principal stresses with respect to an axis of one of the strain gauge elements.

Abstract: A conveying apparatus for use when filling an elongated hollow edible food unit with an edible filling includes an intermittently operable conveyor bearing carriers 10 having troughs in which the food units 23 can be loaded at a loading station (15). The carriers are movable upwardly between guide plates 22 to a filling station (16) at which nozzles 25 carried by manifolds 24 are moved into the units to discharge the filling into the units. The nozzles following filling are retracted to allow the carriers to move upwardly out of the filling station between guide plates 26, which reposition the units in the troughs, and then along an upper horizontal section of the conveyor. The carriers then descend to an unloading station (17) from which the empty carriers return to the loading station. <IMAGE>

Title: Generation of trapezoidal waveforms
Inventor: ROKOS GEORGE HEDLEY STORM
IPC: H03K6/00
Filed: 1984-05-31
Abstract: A circuit generating trapezoidal waveforms including a capacitor (C) which is connected between the outputs of individual identical emitter follower circuits (T1, T2) responsive to balanced differential square wave inputs (S, S). Each emitter follower circuit includes a constant current source (IsA, IsA) feeding the emitter thereof, the outputs of the emitter follower circuits being connected also to control respective transistors (T3, T4) of a long tail pair. The switching of the input signals (S, S) initially causes the emitter voltages (A, A) to move together, since the charge on the capacitor cannot change instantaneously. Then, as charge on the capacitor does change, the voltage difference (A-A) causes output current ramps (I and I) which are limited by the emitter current (I ref). A transistor (T5) may be used to inhibit the action of the circuit. <IMAGE>
