Title: Improvements in and relating to Internal Explosion Engines.
Inventor: MATTHEWMAN WINFRED
IPC: F02D15/04
Filed: 1916-10-26
Abstract: 112,955. Matthewman, W. Oct. 26, 1916. Compression engines; driving-gear.-To enable the explosion pressure to reach its maximum before the commencement of expansion, the compression space is maintained constant for a substantial period after ignition, which occurs when the crank is beyond the centre, by a supplementary piston mounted in or adjacent the cylinder head. In the fourstroke-cycle engine shown in Fig. 1, a camactuated supplementary piston 2 is constrained so that it remains stationary during exhaust, recedes during the suction stroke, and advances with the main piston, to keep the compression space constant, during the early stages of the working stroke. According to a modified construction, the supplementary piston is mounted in a transverse chamber in the cylinder head. A two-stroke-cycle engine is described in which the supplementary piston is mounted in the end of a charging pump, the crank of which is set behind the crank of the working piston in an adjacent cylinder. Alternatively, the extra piston may be mounted in the head of the explosion cylinder. The invention is described also in connection with a two-stroke-cycle engine having terminal inlet and exhaust ports.

Title: Corrugated rubber hose
IPC: B29D23/18
Filed: 1951-06-30
Abstract: An unvulcanized rubber tube is mounted on a perforated mandrel and placed in an inflating box as described in Specification 647,084 and then subjected to a differential internal and external fluid pressure while being restrained by vanes at desired intervals to form circumferential swellings in the tube after which the tube is collapsed axially, preferably on a second mandrel, to produce the desired corrugations, and then vulcanized. A wrapping of flexible but virtually inextensible fabric is applied around the portions of the tube between the corrugations before the tube is placed in the inflating box, or after the tube has been removed from the box and immediately before the axial collapsing step.  When swellings of a given outside diameter are desired the perforated mandrel may be placed concentrically within a larger unperforated mandrel to restrain the swellings.

Patent GB-906774-A (GB)
Title: Improvements in or relating to ribbon feed mechanism
IPC: B41J33/518
Filed: 1960-05-03
Abstract: 906,774. Ink ribbon mechanisms. TELEPRINTER CORPORATION. May 3, 1960 [July 2, 1959], No. 15577/60. Class 100 (4). An ink ribbon mechanism comprises a first spool which attempts to drive a second spool at a higher linear ribbon speed through a frictional slip drive, the first spool being driven by a slow speed reversible motor, the reversing of which is controlled by a switch actuated by a rack arm having ribbon slots which are engaged by the conventional eyelet or like means. A first spool 12 is secured to the shaft 16 of a slow-speed reversible motor 14 and drives a second spool 22 through a friction device F which includes a ratchet-wheel 24. The diameter of the spool 12 when full of ribbon is not greater than the diameter of the empty spool 22 so that when ribbon is being wound on to the spool 22 its linear speed there will be greater than at the spool 12 so that slipping of the friction device F will occur. The ribbon 32 passes through pins 70, 72 of a reversing lever 66, Fig. 2, and when the ribbon on the spool 12 is exhausted the pins 72 are engaged by the usual eyelet which swings over the lever 66 to reverse the drive of the motor 14 by changing over a switch 64. A pawl 30 now engages the ratchet-wheel 24 and holds it against reverse rotation so that with the spool 12 acting as the take-up spool the device F acts as a frictional brake. In a modification, the friction device F is housed in a recess in one spool so that the spools can be mounted closer axially. In a further modification the spools, which may be of a standard pattern, are mounted on separate shafts and a step-up gearing connects them and includes a similar frictional drive device.
