Title: Porous Fibrous Web
Inventor: SHIMWELL RICHARD JOHN
IPC: B29C55/02
Filed: 1965-05-24
Abstract: 1,156,321. Making netting. BRITISH CELLOPHANE Ltd. 24 May, 1966 [24 May, 1965], No. 21919/65. Heading B5A. [Also in Divisions C3 and D1] A porous fibrous web is produced by stretching a sheet of cellular material in at least one direction until substantially all the walls between the cells have ruptured and the remnants of the walls form a net-like structure. The cells are preferably uniformly distributed throughout the material and occupy at least 15% of the volume of the material. The stretching may be carried out in two directions at right angles to each other, as by means of a stenter. Alternatively the cellular material may be clamped in a frame, and fluid applied under pressure to one side, to cause the material to balloon outwardly. The fibrous web may be produced by forming the sheet into a tube and inflating the tube by a fluid under pressure. The sheet may be cellular glass or metal or a polymeric material such as, polyvinyl chloride, polystyrene, a polyester, polyolefin or a polybutene-1. The net-like structure may be further stretched to orientate the molecular structure of the remaining cell walls. The porous fibrous web may also be rubbed between rubber surfaces to develop a soft handle. Several cellular material formations are given. Reference has been directed by the Comptroller to Specification 1,028,450.

Title: Improvements in air compressors
IPC: F02B71/00
Filed: 1933-02-22
Abstract: 415,477. Regulating air-compressors. PESCARA, R. P., 115, Rue de la Tour, Paris. Feb. 22, 1933, No. 22097/34. Divided out of 415,454 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 24, 1933. [Class 8 (i).] In a motor-compressor comprising pairs of opposed freely moving pistons, the pistons of different pairs being connected so that the outstroke of one pair effects the instroke of another, the fuel injection pumps 134 are controlled by the air output pressure so that the amount of fuel and the pressure increase and decrease together. The outlet pipe 137 delivers air to a cylinder 138 in which a piston acting against a spring shifts the pump-regulating rods 135, 136. One pump only may be so regulated, the other being regulated by the reservoir pressure. In addition, rise of output pressure is caused to move pistons 142, 143 so as to cut the delivery off from the reservoir and allow it to escape to atmosphere. The rods 135 may actuate cams so that the fuel delivery increases with output pressure up to a maximum and then diminishes with increasing output pressure. The compressor may deliver air to a motor such as a turbine, Fig. 3, having a speed governor R connected with a distributing valve 158 so that as the pressure of air rises the air is delivered to successively earlier stages of the turbine, while at the same time the fuel supply is increased. The air compressor may be stopped when the length of stroke reaches a maximum by means of a cam actuated by an oscillating lever connected to a pair of opposed pistons, the cam ceasing to act on the control of the feed pumps when the stroke and oscillation increase beyond this maximum.
