Title: Improvements relating to hinges
Inventor: PAYNE WILLIAM JOHN
IPC: E05D7/04
Filed: 1982-04-22
Abstract: This invention relates to hinges and, in particular to hinges including a mounting plate (1) for attachment to the side wall or door of a cupboard and a hinge arm (4) which forms part of the remainder of the hinge and which, in use, is connected to the mounting plate (1) by a bolt (5) passing through a keyhole-shaped slot (15) in the hinge arm (4) and into a screwthreaded hole (14) in the mounting plate (1). The hinge includes at least one abutment (23) formed in the hinge arm (4) between the enlarged portion (16) of the keyhole- shaped slot (15) and the parallel sided portion (17) of the keyhole-shaped slot (15) so that the at least one abutment engages the head of the bolt (5) to prevent the bolt (5) moving from the parallel sided portion (17) of the keyhole-shaped slot (15) unless it has been undone sufficiently to enable the abutment (23) to pass beneath the head of the bolt (5). <IMAGE>

Abstract: A 2-amino-6-diarylaminofluoran derivative is of the general formula:   <IMAGE> where Ar and Ar' are each a C6-20 aryl group, which may have alkyl or alkoxy substituents, or a C4-36 heterocyclic residue, or they together complete a heterocyclic nucleus; R1 and R2 each are H, C1-20 alkyl, C5-7 cycloalkyl, C7-18 aralkyl, C6-20 optionally substituted aryl, or heterocyclic; R3 is H, halogen, C1-5 alkyl or alkoxy, C1-20 alkylamino, C2-40 dialkylamino, C2-20 acylamino, NO2 or NH2;    R4 is H, halogen or C1-5 alkyl or alkoxy; and rings A and B may bear other substituents, e.g. alkyl, alkoxy or halogen. 23 specific compounds are shown. Condensation synthesis is from a p- aminophenol and benzoylbenzoic acid or a fluoran and alkylating or arylating agent. The compounds are used in color forming recording materials, especially microencapsulated in pressure-sensitive material or in a binder in heat-sensitive material. A black or greenish black dye is formed upon contact with an electron- accepting substance such as a clay, organic acid or metal salt thereof.

Patent GB-2115627-A (GB)
Title: Power supplies
Inventor: PIASKOWSKI ANDREW D
IPC: H02M1/00
Filed: 1983-02-08
Abstract: A power supply circuit comprises bridge rectifier circuit (81) connected to a.c. source (80) to provide a d.c. supply (VIn). SCRs (83, 84) are turned on alternately, to pass a cyclically reversing current through a load circuit (86) including at least one discharge lamp (RI). For power factor correction, primary winding (88) of current transformer (89) is connected in the load circuit and second bridge rectifier circuit (93) is connected in series between the first rectifier circuit and the load. A secondary winding (90) of the transformer (89) is coupled to the second rectifier circuit (93) to extract current from the supply. The SCRs are turned on by a transformer circuit which cessation of the free wheel current of the first SCR (83) induces a signal for switching the second SCR (84) and vice versa. If one lamp is removed, the frequency decreases and the current in each remaining lamp is unchanged. <IMAGE>

Patent GB-2137893-A (GB)
Title: Improvements in or relating to conveying screws
Inventor: LIN SIN YAU
IPC: B29C48/03
Filed: 1983-04-13
Abstract: A conveying screw comprises a long, cylindrical rotor 1 rotatable within a stator 2, and a propelling thread 5 is formed on the rotor and extends from one end of it to the other. At least two barrier threads 18-20 are also formed on the rotor, where they are located in axial sequence relative to each other. Each barrier thread is of wider pitch than the propelling thread 5, and each succeeding barrier thread (e.g. 19, 20) is of wider pitch than the barrier thread (e.g. 18, 19) that it succeeds, whereby the interaction of the combination of the propelling thread 5 and each succeeding barrier thread (e.g. 19,20) exercises a stronger mixing and/or pressurising effect upon the material being conveyed than did the combination of the propelling thread with the preceding (e.g. 18, 19) barrier thread. The barrier threads (e.g. 43, 59) may be in the form of a series of aligned barrier elements separated by small gaps (54). <IMAGE>

Patent GB-2145592-A (GB)
Title: Motor control apparatus
Inventor: WESLING HENRY JOSEPH
IPC: H02P7/29
Filed: 1984-07-30
Abstract: A motor control apparatus for a motor (43) having a chopper (40) for regulating the motor current and a filter capacitor (56) is provided with a programmed microprocessor (104) for controlling the operation of the chopper in accordance with a comparison of a sensed voltage change (102) across the filter capacitor with an allowed voltage change determined in relation to the motor current (106). The capacitor bank (56) smooths out voltage changes caused by the chopper (40). If the effective capacitance is reduced (e.g. by an open fuse 76,78), voltage ripple may increase to a point at which generated EMI might interfere with other systems. Ripple is thus detected (102) and compared with an allowed figure that depends on the motor current (106). If necessary the chopper (40) is then controlled to reduce the motor current, or is turned off. <IMAGE>

Abstract: A ground-strength testing device includes a tubular member 1 closed at the top by a weight 2. At the bottom is an aperture 3 from which a probe 4 projects. A spring 6 acting on a plate 5 fixed to the top of the probe 4 biasses the probe 4 into its position of maximum protrusion from the member 1. Lowering of the device onto the ground causes the probe 4 to be retracted and raise a non-return follower 9 until the member 1 comes to bear on the ground. The final position of the follower 9 along a calibrated scale 12 indicates the strength of the ground. <IMAGE>

Title: Weapon guidance system
Inventor: JONES MALCOLM DAVID
IPC: G01S7/41
Filed: 1986-09-08
Abstract: The centroid of the discrete components forming the overall radar return from a target 201 onto which a homing weapon 200 is being guided may not coincide with a desired aimpoint on the target. Herein proposed is the discrimination and comparison of returns from different portions of the weapon sensor's field-of-view, i.e. different portions of the target, and guidance of the weapon in dependence upon the relative values of the differences between those returns. As a result, the weapon can hit say, the centre of a tank turret roof rather than the probably heavily armoured area forward of the turret roof.

Title: Recovering synchronising signals in television recording and/or playback apparatus
Inventor: HEITMANN JURGEN
IPC: H04N5/93
Filed: 1986-09-19
Abstract: A circuit for a magnetic tape television recording and/or playback apparatus comprises at least two magnetic heads 2, 3 arranged around the circumference of a head wheel 1, each field being recorded over several tracks on the magnetic tape 4, and an arrangement 17 for compensating timebase errors of a television signal played back from the magnetic tape. A first demodulator 16 is connectable via a first head switch 15 in turn to the magnetic heads and a second demodulator 21 is connectable via a second head switch 20 in turn to the magnetic heads. The first head switch is switched over during horizontal blanking intervals of the television signal and the second head switch is switched over outside the horizontal blanking intervals, preferably during the line period preceding the switching of the first head switch. This ensures that horizontal synchronising signals otherwise lost due to switching of the first head switch are supplied to the timebase corrector via the second head switch. <IMAGE>
Patent GB-2181505-A (GB)
Title: Slip-controlled brake system
Inventor: FENNEL HELMUT
IPC: B60T8/58
Filed: 1986-09-26
Abstract: To control the braking pressure in the wheel brakes of a slip-controlled hydraulic brake system for automative vehicles with all-wheel drive and with lockable or automatically locking differentials (2, 3), there is provided a circuit configuration influencing the variation of the vehicle reference speed (vREF). That is to say, in the event of the actual wheel velocity (vRn) which is momentarily decisive for the formation of references becoming unstable, the reference speed (vREF) will first be declined for a predetermined time period T1 with a relatively flat gradient which corresponds to a vehicle deceleration at a low frictional coefficient followed by a decrease of the vehicle reference speed (vREF) with a very steep gradient. This latter decrease will continue until the vehicle reference speed (vREF) reaches the decisive wheel speed again or falls thereunder. To avoid oscillations, the change-over to increasing reference speeds (vREF) again after the attainment of the wheel speed curves (vRn) will not be effected until after a predetermined time of delay (t16 to t17, T2 or T3). <IMAGE>
