Title: Improvements in or relating to devices comprising a cylinder-and-piston combination
IPC: F25B9/14
Filed: 1964-12-21
Abstract: 1,081,700. Cylinders; pistons. PHILIPS GLOEILAMPENFABRIEKEN N.V. Dec. 21, 1964 [Dec. 24, 1963], No. 51823/64. Heading F2T. [Also in Division F4] In an expansion engine, compressor or coldgas refrigerator having a piston 2 reciprocable in a cylinder 1 to vary the volume of a working space 4, the width of the annular gap 8 between the upper portion 6 of the piston and the cylinder increases in a direction away from the working space. A seal 7 is provided between the lower portion 5 of the piston and the cylinder. A centring ring 10 having circumferentially spaced apertures 11 is provided in the upper end of the gap. The piston may be used as the displacer of either an otherwise conventional cold-gas refrigerator (Fig. 6, not shown), or a refrigerator in which the frusto-conical part of the piston is filled with regenerative material (Fig. 7, not shown), and has an upper, constantdiameter extension. In further modifications, the gap may increase in a step-wise manner (Fig. 2, not shown), the walls of the cylinder may be downwardly divergent over part of their length and the piston of constant diameter (Fig. 3, not shown), or the walls of the frusto-conical part of the piston may be curved. Preferred dimensions and operating conditions and a preferred relationship between gap width and the thermal conductivity of the working medium are given.

Abstract: 1362588 Recording and playback MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 8 Nov 1971 [6 Nov 1970 7 Nov 1970] 51841/71 Heading G5R In a recording and playback system, wide band signals are converted to narrow band form by first recording the signals on a high speed disc, and then replaying from the disc at a lower speed; the replayed, modified, signals are re-recorded on a tape. In the arrangement shown, individual fields or frames of video signals are selected at 5, 6, 7 from sources 1, 2, and are passed via contacts c and e to a head 14 for recording on a disc 200/201 driven by a high speed motor 103, each field or frame occupying one circular track on the disc. For band changing, a solenoid 25 is energized in order to rotate an arm assembly 101, and hence the disc 200/201 which it supports, so that the disc is brought into edge-contact with a tape 107. A slow speed motor 105 and capstan 106 are then able to simultaneously drive both the disc and the tape, and signals reproduced by head 14 are passed via contacts e, d, h, i and also i<SP>1</SP> whereby a head 22 can re-record on to the tape. The apparatus will also function in reverse to allow narrow band signals on the tape to be re-recorded as wide band signals on the disc. Still frame pictures may be viewed at 11 by replay from the disc and closing contacts f, f<SP>1</SP>. In the Fig. 3 system (not shown), the wide band signals are recorded relative to a marker (110), and during replay the rotation of the disc is controlled by a pulse generator (35). In the Fig. 4 system (not shown), two discs are usable simultaneously. In the arrangements of Figs. 5-9 (not shown), the narrow band signals are transmitted/ received over telephone lines.

Tube bank 22 is heated by passing through it the condensate from chamber 17. The condensate leaving tube bank 22 mixes in flash pot 33 with the condensate withdrawn from chamber 18. Sea water is introduced into the system through line 40, flows in heatexchanger with the condensate and then flows through the cooling-tubes 28 in condenser chamber 18. Some of the water is discharged from the system from tubes 28, and the remainder flows through cooling- tubes 27 in condenser chamber 17. The water next flows through the condenser 43 for ejector 50, and is then conveyed through line 26 to spray nozzles 27' and 30.
