Title: Improvements in or relating to coaster hubs for cycles
IPC: B62L5/04
Filed: 1934-05-16
Abstract: 418,190. Coaster hubs. SEIBAEK, A. C., 6, Kigkurren, Copenhagen. May 16, 1934, No. 14754. [Class 136 (ii).] A free-wheel and back-pedalling brake hub for cycles comprises balls, rollers, or like members 11, 17 mounted in openings or guides in a cage or bush 13 in such a way that the balls &c. 11 are displaceable radially to drive the hub casing 4, and the balls &c. 17 are displaceable axially to actuate the brake. The balls 11 engage radially-inclined grooves 10 in a driver 6 rigid with the sprocket 7, so that on forwarddriving they are forced out into engagement with grooves 12 in the hub casing 4, the balls being arranged in two or more annular rows and in staggered relation in adjacent rows, so that the driving forces are evenly distributed. On back-pedalling, inclined teeth 16 on the end of the driver 6 displace the balls 17 axially, thereby forcing a bevelled disc 21 against the bevelled edge of a brake sleeve &c. 22, which is thus expanded against the hub casing 4. The cage 13 has a hub 20 rotatably mounted on the axle 1, and the disc 21 is mounted on the hub 20 and is prevented from rotating relatively to the brake-sleeve 22 by a pin 24 adapted to engage a slot in the sleeve. Rotation of the cage 13 is checked by a drag spring 25 fixed at one end to the disc 21. 418,246. Hand - propelled vehicles. PLANT, F. W., Cambridge Arterial Road, Enfield, Middlesex, and ROE, J.

Title: Echo sounding method and apparatus
IPC: G01S15/96
Filed: 1970-03-26
Abstract: 1,272,526. Echo-sounding. FRIED. KRUPP G.m.b.H. 26 March, 1970 [28 March, 1969], No. 14872/70. Heading H4D. In combination with an echo-sounding system there is provided a system for determining at a measuring station the instantaneous value of a variable, converting this value by pulse duration modulation to a signal corresponding to the value, and transmitting this signal over a signal channel to a remote observation station. In the Fig. 2 embodiment the measuring station 1 is on a trawl net, the observation station 2 is on a fishing vessel, the signal channel is a cable 3 or an acoustic link, echo-sounding gear 4 on the net is used to give on chart recorder 10 records of the net distance D2 from the sea bed, D1 from the sea surface, and of the net opening D3, and the measured variable is water temperature T at the net. A voltage representing T is derived by unit 19 from temperature sensor 18 and converted by modulator 20 to a pulse K of proportional width. By way of transformer coupling 31 and pulse-generator 24 the leading edge of pulse K is synchronized with the transmission of an echo-sounding pulse S (or, by means of amplitude threshold circuit 25, with an echo pulse E). The trailing edge of pulse K triggers monostable 21 which in turn gates oscillator 22 to give a brief burst of carrier frequency constituting an artificial echo signal E<SP>1</SP> which is coupled via transformer 31 to the chart recorder 10. To distinguish the artificial echo recording from the normal echo recording, pulse generator 24 is arranged to trigger once for every n echo-sounding pulses, so that successive artificial echoes have greater spacing than the normal echoes. A digital indication of temperature is derived at 17 from the artificial echo, which may be distinguished from the normal echo by giving the normal and artificial echoes different carrier frequencies and using a frequency filter 16. When an echo-range selector 11 for recorder 10 is adjusted, the temperature scale is kept the same by using a counter 23 to sense the resulting change in sounding pulse S repetition frequency and to make a compensating adjustment of the voltage/pulse width factor of modulator 20. A switch 28 which closes when sounding pulses S are present, and a waterpressure switch 29, may be used to control current from battery 30 to the measuring station circuits to conserve power. The Fig. 2 system may be extended (Fig. 7, not shown) for sequentially sampling and measuring several variables (e.g. temperatures at the top and bottom of the net, water salinity and fullness of the net) in conjunction with sounding in different directions sequentially.

Title: Extracorporeal blood oxygenator and blood temperature controller
IPC: A61M1/36
Filed: 1973-03-28
Abstract: 1419551 Blood oxygenating and temperature controlling device R C BRUMFIELD 28 March 1973 [31 March 1972] 14911/73 Heading A5R [Also in Division B1] An extra-corporeal blood oxygenator and blood temperature controlling device, suitable for exchanging oxygen for carbon dioxide in a patient's circulating blood, comprises small diameter oxygenator tubes 11, Fig. 1, having equal lengths, disposed in a parallel array between a base header plate 17 and a top header plate 18, the header plates being fluid impervious and securing the tubes; a boundary case 19 enclosing a space through which the tubes 11 extend; two conduits 21, 22 for leading heat transfer fluid into and out of the case 19; the oxygenator tubes 11 serving for carrying a twophase mixture of blood and oxygen plus carbon dioxide gas, the tubes 11, header plates 17, 18 and case 19 forming a heat exchanger for transferring heat between the heat transfer fluid and the mixture. The heat transfer fluid enters by conduit 21, flows to the top of the space within case 19, and returns via tubes 24 to the outlet conduit 22. The patient's blood flows into a mixing chamber 44 below the tubes 11, through inlets 37 (duplicated for safety). The base of chamber 44 is formed with fine holes through which oxygen is passed forming a foam with the blood; this foam is heated and passes upward through tubes 11. As it moves the oxygen partially replaces carbon dioxide in the blood so that the foam emerging above plate 18 contains blood, oxygen and carbon dioxide, which flows into a defoaming chamber 47 bounded by defoaming sponge material 48 with a thin coating of a silicone composition which causes blood foam to collapse. Blood passing through material 48 collects in a reservoir 65 bounded by an outer casing 51, and out to the patient through one or both of a pair of outlets 53. Carbon dioxide and excess oxygen are vented through slits (56), Fig. 6, not shown, at the top 55 of casing 51. Apertures (59) in the top 55, 60 in the base of casing 51, and 61 in the chamber 44 are provided for a hypodermic syringe and may have rubber plug closures. In a modification, Fig. 8 (not shown), the wall of the chamber 44 has inverted castellations (82). The parts may be made of plastics materials which do not interact with blood, e.g. polycarbonate, polypropylene, polyethylene and some polyvinyl chloride compositions, by injection moulding where appropriate. Joints may be made by cementing, ultrasonic sealing or by dielectric sealing. Advantageously, the tubes 11 may be made of polycarbonate. One or more of the tubes may be plugged to adapt the apparatus for patients ranging in size from juveniles to adults.
