Title: Improvements in or relating to fishing reels
IPC: A01K89/06
Filed: 1933-12-15
Abstract: 429,774. Fishing. MARTIN, W., Eel's Foot Hotel, Ormesby St. Michael, near Great Yarmouth. Dec. 15, 1933, No. 35295. [Class 48] A fishing-reel for sea angling is turned from the winding position to the casting position after the weight has started to travel in its forward direction by a spring B. The reel is normally held in the winding position by a lever A engaging a pin D projecting from the reel spindle C. When making a cast, the lever A is turned to release the pin D and the reel is held in the winding position by the finger until the beginning of the cast. To reverse the winding of the line, a single turn is made round a pin projecting from the side of the reel. Specification 211,406, [Class 48], is referred to.

Title: Improvements in or relating to means for measuring, regulating and/or indicating theflow of fluids
IPC: G01F1/38
Filed: 1937-12-21
Abstract: 507,853. Fluid - pressure servomotorcontrol apparatus. ASKANIA-WERKE AKT.-GES. Dec. 21, 1937, No. 35365. Convention date, Dec. 21, 1936. [Class 135] Apparatus for controlling, measuring, or indicating the ratio of fluid flows in two or more conduits by means of a fluid-pressure relay 3 comprises a rotary fluid motor 13 for deriving an impulse varying directly with the fluid flow in one of the conduits and a centrifugal governor 17 which converts this impulse into a further impulse bearing a quadratic relation to the first impulse and acting in opposition to an.impulse varying as the square of the fluid flow in another conduit on the fluid relay. As shown applied to a proportion, regulator for combustion air and fuel oil in conduits 2,. 1 respectively, a rotary motor 13 of the sliding vane type, through a shaft 14 drives a rotatable table 15 carrying bell-cranks 18 with fly weights 17. Additional weights 28 are provided for adjustmont purposes. The levers 18 through a collar 19 and a thrust rod 20 control a jet pipe relay 21 the control pressure from which is led through a conduit 25 to a diaphragm 27 which influences the main relay 3 and to a chamber 29 containing a diaphragm 30 which is influenced by the fluid pressure to restore the jet pipe 21, the upward movement of which is limited by a stop 31. The impulse from the diaphragm 27 is balanced against that from a diaphragm 10 subjoct to the differential pressure across a restriction 6 in the air conduit 2. The main relay 3 which is also of the jet type controls a servomotor 4 operating a valve 5 in the air conduit. Both relays may be provided with adjustable ratio sliders 12, 33. The thrust rod 20 may act directly on the relay 3, but the auxiliary relay 21 is preferable where fuel oil and fuel gas are used selectively as shown in Fig. 1. By moans of three-way cocks 38, 39, the two sides of the diaphragm 27 may be selectively connected to opposite sides of a restriction 35 in the fuel gas conduit 34 or to atmosphere and the control conduit 25. In the former position the conduit 25 is shut off by a cock 43, the cocks 38, 39, 43 being operated simultaneously by a common handle. An indicating and recording device 44 connected to a diaphragm 45 which by means of conduits 46, 47 is subject on its opposite sides to the same pressures as prevail on the diaphragm 27, registers the flow in either of the conduits 1, 34. In place, of the ratio slider 33, the motor shaft 14 and the governor shaft may be offset from one another and connected. by an infinitely variable friction gear. The Specification as open to inspection under Sect. 91 states that the centrifugal governor and the rotary fluid motor may be utilised in conjunction with a spring-loaded jet pipe relay to control the flow in a single conduit. This subject-matter does not appear in the Specification as accepted.

Abstract: 1357334 Lung ventilators BRITISH OXYGEN CO Ltd 21 July 1971 [21 July 1970] 35391/70 Heading A5T A lung ventilator capable of supplying gas selectively at either a constant, increasing or decreasing flow rate comprises a flow path 8, 14, 20; a first gas reservoir 12 in the path; a first orifice 10, placed upstream of the first reservoir 12; a bypass path 6 which may be selected by a two-position valve 4, extending from upstream of the first orifice 10 to immediately downstream of the first reservoir 12; a second orifice 26 downstream of the first reservoir 12 and the bypass path 6, and having a larger cross-sectional area than the first orifice 10; a valve 16 between the bypass path 6 and the second orifice 26; and a second gas reservoir 24 adapted to have its interior placed selectively in communication with the atmosphere, via 28, or with the path 20 between the valve 16 and the second orifice 26. The second reservoir 24 is connected to the path 20 by a path 18 having a two-position valve 22. The cross-sectional area of the orifices, and the internal volume of the reservoirs, may be adjustable. Alternatively each orifice or reservoir may be replaced by a plurality of orifices or reservoirs of differing cross-sectional areas or internal volumes respectively, of which a particular orifice or reservoir may be switched selectively into its operational position. A constant inspiratory flow rate is obtained by positioning the valves so that gas passes through the bypass path 6 to the second orifice 26. A decreasing flow rate is obtained by passing gas through the first orifice 10 and first reservoir 12 to the second orifice 26, the first reservoir 12 having filled during the expiratory phase, in which the valve 16 is closed by a suitable automatic control. An increasing flow rate is obtained by passing gas through bypass path 6 to the second orifice 26, some of the gas being diverted into the second reservoir 24, which is then vented to the atmosphere in the expiratory phase, in which the valve 16 is closed.

The slide-member 5 is retained between a cover plate 3 and a base plate 6 secured together by bent over tabs 3b, and is worked by a handle 5b. The plate 3 has holes 3a through which the rings pass. The assembly is secured to the cover E by staples 7 held under a lining S and soldered to the plate 6. In a modification, the ball 2 is replaced by a projection on the ring and the plate 4 by separate guide plates for each ring. The plate 3 is then provided with a hole 3a and a slot for each ring, and the assembly is secured to the cover by tabs on the plate 6 passing through the lining S and through a plate underneath the lining. Two operating slides, worked from opposite ends of the binder, may be provided.
