Patent GB-1413715-A (GB)
Title: Radio or television receiver housing
IPC: B62J11/00
Filed: 1973-05-14
Abstract: 1413715 Mounting articles on cycles J ENGELMANN 14 May 1973 [3 Aug 1972] 22810/73 Heading B6J [Also in Divisions E2 and H3-H5] In a radio or television receiver housing 1 having means for mounting it on a vehicle including a fixing or securing element 4, 5 connectable to the vehicle and removably secured to the housing 1 the housing and the fixing or securing element are interconnectable by means of a dovetail joint 2. The radio or television receiver housing is shown for mounting on the handle bar of a bicycle by a slip which consists of an upper port 4 moulded from plastics and a strip metal strap 5 clamped together about the handle bar by screws 6. The upper part 5 has a dovetail part 7 and is wedge shaped (Fig. 3, not shown) and engages in a corresponding shape recess 2 on the underside of the housing. A projection 9 on the housing projects into a channel shaped recess in the upper part 4 to facilitate the housing 1 being slipped into position by a resilient deformation of the parts 1 and 4. The projection 9 prevents the dovetail coupling from being accidently detached. In a modification to the clip (Fig. 5, not shown) the projection 9 is replaced by a lug (10) on the upper part 4, to which the housing 1 is fastened by a screw (11).
Patent GB-679424-A (GB)
Title: Improvements in or relating to gain control networks for electric wave amplifiers
Inventor: HARGREAVES THOMAS FREDERICK ST
IPC: H04B3/12
Filed: 1950-09-18
Abstract: 679,424. Automatic gain control. STANDARD TELEPHONES & CABLES, Ltd. Sept. 18, 1950, No. 22856/50. Class 40 (iv). [Also in Group XL (c)] In a negative-feedback amplifier the cathode of a valve 11 in one stage is coupled to the cathode of a valve 9 in an earlier stage through a variable equalising network 12, 7, 6, 8, 4, including a variable resistor 4 having a reference value Ro, the network having two branches 7, 12 and 6, 8, 4 respectively connected in parallel to the cathode of the valve 9. One of the said branches 7, 12 has an impedance KRo and the other, which includes the variable resistor 4, an impedance (L+1) Ro, where K and L are constants connected by the relationship L(K+L)=1. In order to fulfil the requirements of stability the equaliser 7, which as shown comprises a bridge-T network, is chosen so that the loss introduced tends to zero as the frequency tends to an infinite value. The equaliser 8, as shown, comprises a bridge-T network of inverse form to that of the equaliser 7. The theoretical basis of the invention is discussed in the Specification, which refers in this connection to Specification 469,067, [Group XL]. The invention is primarily applicable to the automatic equalisation of cable characteristics, the resistor 4 comprising a thermistor controlled by pilot currents transmitted with the signals.

Title: Improvements in corner-cramps
IPC: A47G1/10
Filed: 1929-07-26
Abstract: 330,178. Dombrain, H. A. A., and Bamber, M. W. July 26, 1929. Cramps for picture frames &c. comprise a framework A on which the work rests, carrying lugs B, B' to contact with the outside of the frame. An adjusting screw C carries a block D on which are pivotally mounted gripping jaws E. When these grip the work, a final adjustment is effected by a wedge-shaped cam operated by a handle F which forces apart the rear ends of the jaws E against the action of a spring, thereby bringing the two members of the frame into closer contact.

[Also in Division C3] A food product comprises a fat or a flavouring and/or colouring material in admixture with an expanded protein product which is made by cooking a dough, produced by mixing together a proteinaceous material containing at least 35% by wt. of protein and an aqueous liquid under isobaric conditions (i.e. of constant external pressure) at a temperature sufficient to vaporize some of the water, thereby forming an expanded, water-insoluble, cross-linked structure. The proteinaceous material may be oleaginous seeds, e.g. soybean, sesame, cottonseed, peanut, soy flour or protein, which may be partially hydrolysed or mixed with dairy whey. Food products are exemplified in examples 4, 8, 12, 21, 22 and 26.

Abstract: 673,613. Vacuum cleaners. HOOVER, Ltd. Sept. 20, 1950 [Sept. 21, 1949], No. 23059/50. Class 8 (i) In a vacuum cleaner fitted with floor wheels and an agitator rotated by the belt 13 the agitator may be replaced by a rotary brush 30 driven by the belt 13. The brush 30 is carried by supports 27 in a frame 21 that also carries shrouds 32, 33 pivoted on pin 31 and pressed apart by springs 36 ; the shroud 33 has a slot 42 to permit the passage of the belt 13. The frame 21 has studs 24, 26 which fit slots in the ends of the nozzle 12, the stud 26 having a flat so that the assembly can be inserted into the nozzle the correct way that the belt 13 passes through the slot 42. The edges of the shrouds are bent outwardly at 40, 41 to engage the front and rear edges of the nozzle so that when in place the shrouds substantially close the nozzle mouth from the fan inlet to reduce the load on the motor during polishing.

Title: Improvements in and relating to closure caps
Inventor: MUMFORD GEORGE VICTOR
IPC: B65D79/00
Filed: 1964-06-04
Abstract: 1,061,801. Caps for bottles &c. OWENSILLINOIS Inc. June 4, 1964, No. 23106/64. Heading B8T. A sheet metal closure cap for hermetically vacuum sealing a bottle &c. comprises a disclike panel 16 with a peripheral depending skirt 17, the panel comprising a flat annulus 12, a normally outwardly convex resilient central part 18, and a sealing gasket 13 on the cap. The sheet metal has a Rockwell hardness of 54 to 72. When the cap is placed on the container, lugs or a bead or screw threads 20 being forced over lugs or a rib or screw threads 15, and an air-tight seal has been obtained, the container is subject to a vacuum so that the central part 18 is sucked in and becomes concave. When the vacuum seal is broken by removing the cap, the central part 18 becomes convex once more, and this change is accompanied by an audible click, thus indicating that a vacuum was present. These changes can be used to detect containers not fit for use by mechanical or photo-electrical devices, the concavity of the central part 18 focusing light rays in the latter instance.
Patent GB-598737-A (GB)
Title: Improvements in or relating to electric motor control systems
IPC: H02P3/06
Filed: 1945-09-07
Abstract: 598,737. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd. Sept. 7, 1945, No. 23123. Convention date, Sept. 8, 1944. [Class 38(iii)] Any desired control in accordance with the rate of deceleration of a motor is obtained by means of a charged condenser and a control winding connected across the armature of the motor so that the discharge rate of the condenser increases with the rate of deceleration of the motor. As shown an electromechanical brake B, for example of a D.C. hoist motor M, is controlled in accordance with the rate of deceleration of the motor during dynamic braking by charging a condenser C from the armature volts and permitting this condenser to discharge through the holding coil C1 of a relay DR as the motor slows up. When the rate of retardation is below a predetermined value, or when the motor comes substantially to rest, the current in this coil becomes insufficient to hold in the contact d of the relay DR and a relay BR, which keeps the release magnet of the brake B energised, then opens its contacts. The actuating winding c of the relay DR is shunted to delay opening until a relay DB has had time to close the dynamic braking circuit. Should the motor accelerate instead of slowing down a rectifier R ensures that the coil C1 is unexcited and the brake B will be immediately applied.
