Abstract: 1,090,373. Spiked plates. BEVES & CO. Ltd. Dec. 23, 1964 [Jan. 9, 1964], No. 1043/64. Heading F2H. A metal plate 1 for connecting timbers has slots 4 providing spikes 3 extending perpendicularly from one face and grouped in at least two zones with an imperforate zone 5 between while lines of weakening 2 are provided at intervals along a length of metal sheet so that a plate can be broken off as required for use. The spike points are unsymmetrically tapered and the base 6 of each spike is set at an angle to an axis separating the spike zones and bisecting the imperforate zone 5. This setting is facilitated by making the slot sides unequal, but alternatively the slots 4 may be formed at an angle to the zone 5 or, if the sheet is of thin metal, the spikes may be twisted. Some of the spikes in a zone may be set transversely to the others in that zone. The spikes shown as set at an angle, may also be twisted and swaged along their length, Fig. 3 (not shown).

Title: Improvements in or relating to stiffening materials for footwear and other articles
Inventor: MARTENS ROBERT
IPC: A43B23/16
Filed: 1954-01-15
Abstract: Stiffeners, e.g. for leather toe-caps, consist of a fabric, felt, or fibre fleece impregnated with a water-soluble, hardenable, pre-condensate of a synthetic resin, and also with an aqueous dispersion of a polymer of vinyl chloride or acetate or of an acrylic or methacrylic ester, so as to incorporate 60-95 per cent of the pre-condensate and 5-40 per cent of the polymer. Urea- or melamine-formaldehyde pre-condensates, or a phenol-aldehyde resol, may be used.  Fillers such as wood meal, cotton flock or linters, silica or alumina gel, or kieselguhr may be added.  In an example a mixture of an aqueous solution of a urea-formaldehyde condensation product, an oleoresin, and kaolin is rubbed through a funnel mill and mixed with an aqueous dispersion of polymethyl acrylate containing ammonia.  A coarse mesh fabric is impregnated with the mixed dispersion and dried. Stiffeners are stamped out from the product, and, before use, are immersed in a solution of ammonium chloride which acts as a hardener for the ureaformaldehyde condensate.

Title: Improvements in or relating to sound amplification systems
IPC: H04M9/08
Filed: 1947-01-14
Abstract: 626,912. Public address and like systems. STANDARD TELEPHONES & CABLES, Ltd., HILL, S. S., and CRAGG, W. D. Jan. 14, 1947, No. 1269. [Class 40 (iv)] [Also in Group XL (b)] In an electric sound amplification system or loudspeaking telephone system " howling " arising from acoustic feed-back is prevented by continuously varying the phase of the signals. The signals from the microphone M after amplification at MA are fed via the secondary windings of transformer T1to the two-phase displacing networks N1 and N2, the outputs from which differ in phase by 90 degrees and are applied to diametrically opposite points of two circular resistances 1R and 2R having corresponding mid-points connected together. The output is taken from the transformer T2 via contact arms P and Q, which are rotated ganged together with one displaced 90 degrees from the other. The arrangement results in a continuous variation of phase, Figs. 2-5 (not shown). The networks N1, N2 may be of lattice form, Fig. 6 (not shown). The same result may be obtained by replacing the two potentiometers by a rotating transformer.

Title: Improvements in springing arrangements for vehicles
IPC: B60G17/04
Filed: 1959-01-13
Abstract: 855,257. Road vehicle spring suspensions. DAIMLER-BENZ A.G. Jan. 13, 1959 [Jan. 14, 1958], No. 1272/59. Class 108(2). Suspension movements due to loads applied simultaneously to all four road wheels 1, 2, 3, 4, are transmitted by respective hydraulic devices 6 to a single hydropneumatic spring 14. Hydraulic motor pump units 16, 17, 18, 19, are interposed in the hydraulic connections as shown. The units 17 and 18 are connected by a coupling 21 which also functions as a torsion rod. The units 16 and 19 are similarly coupled by a torsion rod 20. The arrangement is such that when the road wheels of a diagonally opposed pair (e.g. the wheels 2 and 3) are deflected in opposite directions the torsion rods 20 and 21 are stressed. They are not stressed when diagonally opposed wheels are deflected in the same directions. Thus on simultaneous deflection of all four wheels only the spring 14 is stressed. When the front wheels only pass over a transverse ridge all the springs 14, 20, and 21 are stressed resulting in a soft suspension. On pitching movements due to acceleration and braking, and rolling movements due to turning only, the springs 20, 21 are stressed, thus giving a hard suspension. None of the springs are brought into action against twisting of the body under diagonal loading. The units 16, 17, 18, 19 may be made of different sizes to influence steering properties of the vehicle.
