Patent GB-384030-A (GB)
Title: Improvements relating to rubber and like compositions
IPC: C08K3/06
Filed: 1931-10-16
Abstract: A concentrated aqueous dispersion of natural or synthetic rubber is mixed with a sufficient quantity of cement to cause the mixture to set and sufficient vulcanizing agent to give an ebonite-like product; the mixture is shaped, allowed to set, and vulcanized.  The composition may be rolled into sheets or applied to a surface by spreading or by spraying.  The cement should amount to 40 per cent by weight of the quantity of liquid in the dispersion except when the mixture is to be sprayed, in which case smaller amounts may be used. The dispersion should contain at least 50 per cent of rubber, and the vulcanizing agent should amount to at least 25 per cent of the dry rubber present.  Fillers may be added if desired.  A typical mix for spreading on a surface consists of "Revertex" 132 parts, sulphur 35 parts, accelerator 2 parts, alumina cement 15 parts, and paraffin oil 10 parts. Specification 214,224, [Class 70, Indiarubber &c.], is referred to.

Title: Improvements in or relating to circuits for stabilizing a display on a screen
IPC: G01S3/28
Filed: 1970-06-15
Abstract: 1,271,903. Radio navigation. BENDIX CORP. 15 June, 1970 [25 June, 1969], No. 28817/70. Heading H4D.  To stabilize a visual display corresponding to sources providing pulse trains of different phases having a fixed repetition rate, received pulses are averaged in synchronism with the pulses in the pulse trains to afford pulses for deflection in the display corresponding to each pulse train. The invention reduces " bounce " of the spots on a cathode-ray tube (C.R.T.) display due to ground reflections received substantially simultaneously with the direct waves of the emissions from spaced microwave beacons in a system such as is described in Specification 966,622 for providing a display corresponding to the outline of a runway. In the embodiment an airborne receiver 4, Fig. 1, produces outputs E 3 , E 4 , E 6 , as illustrated in Fig. 2D, E, F, there being three ground beacons. Pulses E 9 , E 9A , E 9B , Fig. 2G, H, I, are derived from train E 6  and trains E 10 , E 10A , E 10B , Fig. 2J, K, L are generated by circuits 17, 17A, 17B for application to smoothing circuits 18 ... 19B. In a smoothing circuit, e.g. 18, Fig. 4, the deflection pulses E 3 , Fig. 2D, are switched by pulses E 10 , Fig. 2J, to a smoothing network 40, 41, 42, the number of pulses averaged being determined by resistors 40, 42; reading out is controlled by a train E 12 , Fig. 2M, from circuit 20, Fig. 1, to afford average horizontal deflection pulses E 13 , Fig. 2Q, and mutatis mutandis for the other smoothing circuits. Bright-up for the C.R.T. is produced by a train E 17 , Fig. 2W, from circuit 20. The invention also reduces the effect of interference e.g. from radars on the same frequency as the beacons.
