Title: Improvements in or relating to the Pumping of Viscous Substances.
Inventor: NEWBIGIN HENRY THORNTON
IPC: F04D5/00
Filed: 1918-08-26
Abstract: 128,069. Newbigin, H. T. Aug. 26, 1918. Fluid - friction apparatus; multi - stage pumps. - Thin wedgeshaped films of viscous fluid such as oil are formed between relatively moving surfaces contained within a cylinder so that adhesion of the viscous fluid to a moving surface causes it to be carried into the thinner end of the wedge-shaped space. An increase of pressure in the fluid towards the thin end of the wedge is thus caused, and is used to produce a pumping action. One form of rotary pump carrying out this method comprises a rotary impeller provided with three surfaces a<1> of the kind mentioned moving inside a fixed cylindrical casing c supplied through an inlet g with viscous fluid such as oil. There is a slight angle between each of the surfaces a' and the casing c which may be formed permanently, or may be obtained by the projecting part of each surface a<1> being arranged to deflect under the wedging action of the oil. The oil is thus forced by the rotation of the impeller down the passages i into the common passage i<1> in the centre of the impeller shaft and so to the outlet. The thickness of the oil film in the space between the surfaces a<1> and the casing is adjusted by moving the impeller by means of packing slightly endways in the casing c, which is slightly tapered for this purpose. Such units may be arranged in series on a common shaft to form a multi-stage pump, in which the delivery end of the unit forms the inlet for the next so as to increase the final pressure. Disks provided with circumferential packing are mounted on the rotor shaft between the pumping units, and fit the casing to separate the unite effectively. Two similar sets of units are mounted on the same shaft, but with their outlets directed towards a common centre to avoid end thrust.

Title: Time compression of audio signals
IPC: H04N5/91
Filed: 1973-03-26
Abstract: 1433411 Audio compression WESTING- HOUSE ELECTRIC CORP 26 March 1973 [7 April 1972] 14332/73 Heading H4R Audio signals are converted to video format by producing time-compressed segments of duration corresponding to the picture portion of a video line and inserting video sync. signals in the gaps between them. General.-The audio signals are read into a store, read-out faster and recorded with the sync. signals on a magnetic disc or tape. The system described uses a 525 line standard. Compression.-The audio input 101 is restricted 102 to 6 kHz, converted 103 to a sevenbit code and read-in to register 104 at 15750 Hz (i.e. 525 x 30) governed by the reference track on the disc. The track has 525 recorded pulses of which one is distinguishable via integrating and differentiating discriminator 111 to generate signals f 1  of one pulse every revolution (33 msec.) and f 2  to. 525 pulses per revolution. Operation of start circuit 110 and detection of an f 1  pulse produces a reset signal S for the dividers. When 526 f 2  pulses have been counted in divider 115 it opens gate 118 via delay 117 to read-out register 104 at 10 MHz from source 119. The D/A converted and 4 MHz filtered output occupies 53 Ásec., corresponding to a video picture portion, and is frequency modulated 107 on a carrier gated 108 for a line period of 64 Ásec. by divider 115. This cycle is repeated 252 times as determined by divider 122 to gradually build up half a track of recording after which generator 123 suppresses ten f 2  pulses to provide the 10-line vertical blanking interval. After the next 252 cycles divider 124 blocks gate 113 for an extra f 2  pulse making an 11-line blanking interval, and switching to the next track. A waveform generator 18 phase-locked 16 with disc rotation inserts the corresponding vertical blanking and sync. signals. Phase discontinuities between recorded FM bursts occur in horizontal sync. intervals and are not noticable. The recording is reproduced through an amplifier (22, Fig. 3, not shown) which inserts the horizontal blanking and sync. signals and possibly identification codes in line 525 before re-recording on a broadcast video tape recorder (24). Expansion.-The original audio signals are recovered by reproducing the disc through similar equipment (Fig. 5, not shown) having transposed A/D converters, demodulator and data rates with the waveform generator 18 replaced by a reference such as 60 Hz mains. Refinements.-Read-out during vertical blanking intervals loses audio data which may be replaced by the use of parallel registers alternately reading-in and reading-out (Figs. 10, 11, not shown). Display.-A disc carrying compressed audio interspersed, e.g. in alternate tracks with video signals is displayed by detecting a video code, temporarily storing (Fig. 13) and continuouslydisplaying the stored video on a monitor whilst the corresponding audio signals are expanded (216) and reproduced.
