Abstract: 1488358 Patient ventilator apparatus SANDOZ Ltd 24 Sept 1974 [28 Sept 1973] 41604/74 Heading AST [Also in Division F2] A fluidically controlled patient ventilator comprises a, patient breathing hose 28 connected to a bellows apparatus 10 for supplying a predetermined quantity of air to the hose, and a control circuit comprising a fluidic flip flop 60 switchable into first and second states to control the bellows in inspiratory and expiratory phases respectively, a fluidic inspiration timer 80, a fluidic expiration timer 74, a fluidic trigger circuit 72 which provides a switching signal to the flip flop in response to a minimum pressure in the hose, a fluidic pressure limit circuit 78 coupled to the hose, a volume limit signal generator 32, 34, 36, and a switch 58 for de-energising the trigger circuit or the exhalation timer. In addition, there is provided a manually operable inspiration triggering device 70 and a manually operable expiration triggering device 76. In a "control" mode of operation, the flip flop is switched to effect an inspiratory phase by a signal from expiration timer 74 or from manual device 70, the trigger circuit 72 being de-energised, the inspiratory cycle being terminated by a signal from manual device 76, pressure limit circuit 78, the volume limit signal generator, or inspiration timer 80. In an "assist" mode, switching to the inspiratory phase is effected by a signal from the trigger circuit 72 or from manual device 70, the expiration timer being de-energised; while in an "assist/control" mode both trigger circuit 72 and expiration timer 74 are energised. Display devices 82, 86, 90 indicate respectively the output of a signal from the pressure limit circuit, the inspiration timer, and the trigger circuit. The ratio of the inspiratory to the expiratory phase may be adjusted by means of an adjustable by-pass valve 120 associated with the inspiration timer. A conduit 122 is provided for coupling to a nebulizer device, the nebulizer being operable intermittently or continuously. Oxygen from a source 46 energises the control circuit and is used to pressurize a bellows chamber 14 to cause the collapse of a bellows therein to supply air to the patient hose. On expansion of the bellows, oxygen is forced out of the chamber 14 and through a mixing valve 44 where it is mixed with air and then supplied to the bellows. The oxygen from the bellows chamber may however be vented to atmosphere through valve 44.

Title: Improvements in or relating to single-lens reflex photographic cameras
IPC: G03B19/12
Filed: 1958-12-24
Abstract: 899,076. Controlling exposures in reflex photographic cameras with detachable diaphragm-containing objective. GAUTHIER G.m.b.H., ALFRED. Dec. 24, 1958 [Dec. 24, 1957], No. 41633/58. Class 98(1). In a single lens reflex camera having a shutter adjacent the lens and an interchangeable lens assembly, the interchangeable lens assembly has a built-in diaphragm and is arranged in front of the shutter blades and there is arranged on the shutter (a) a setting and preselecting device for the diaphragm, (b) a device for opening the diaphragm and the shutter blade for focusing purposes, and (c) an exposure control mechanism by means of which the setting and preselecting device for the diaphragm and the setting device for the shutter speed are coupled to a follow-up member for the pointer of an exposure meter arranged on or in the camera. As shown, a detachable lens mount 5 is secured by lugs 7 on bayonet sockets 6a on a shutter housing 2 secured to the camera 1. A shaft 16a driven by follow-up adjustment of the exposure meter on the camera body carries a lever 17 spring- urged anticlockwise so as to be engageable against a pin 22 on a lever 20 carried by a floating pivot 19 engaging a control cam 13d on the film sensitivity setting ring 13 and disposed on a lever 18 pivoted on the shutter front plate 4. By depressing a handle 14 on the film sensitivity setting ring 13 pins 26 separately supported thereon and adapted to engage in toothed recesses 9d in the diaphragm setting ring 9 are disengaged and allow the ring 13 to be moved to a chosen film speed setting, whereafter on releasing the handle 14 one of the pins re-enters a recess 9d, thus positioning the cam 13d and so the pivot pin 19. By pressing inwardly against a spring 23 a handle 25 fixed to a coupling member 24, the diaphragm setting ring 9 is released from the speed setting ring 12. Either or both rings may be adjusted until a follow-up pointer or a mark on a scale is aligned with the meter pointer. Release of the handle 25 re-engages the stop and speed setting rings whereafter any related pair of settings may be selected. For focusing purposes, a member on the camera body is provided to operate a gear 34 on a shaft 33 carrying a gear 35 driving through gear 36 a pinion 37 engaging a rack 31b on a ring 31 to move the ring anticlockwise so that a pin 31a engages a depending arm 8 on the diaphragm to open it fully while near the end of the movement a surface 31c engages an arm 39a attached to a ring carrying the shutter blade pivots to open the shutter.

The block is made of a flexible material, and at its lower end is formed with projections 14 and 18. Projection 18 is separated from the main body by a V-shaped slot 20, and has a convex outer surface. Flange 34 of the rail 12 is inserted above projection 14 and as a force is exerted flange 36 rides along the outer surface of projection 18 flexing said projection until it passes point 24 when the projection moves outwardly again until the flange 36 abuts surface 32 on the lower part of the main body. A slider 26 may clip over the outer surface of flange 18. If the terminal block is to be mounted in an aperture in a board, a flange is provided which extends outwardly of the main body portion and snaps into position behind the board.

IPC: G03C7/14
Abstract: 418,040. Colour photography; optical systems. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. July 31, 1933, No. 21476. Convention date, July 29, 1932. Addition to 383,795. [Classes 97 (i) and 98 (ii).] The method according to the parent Specification of projecting multicolour pictures made on lenticular films is modified by employing as the light-dispersing optical element a prism-grating which produces spectra by interference. The Specification sets forth, in connection with drawings, the underlying theory, and states that such a grating uses the whole of the effective light in producing a single lateral spectrum having uniformly distributed brightness. Details are given regarding the mesh, angle of refraction, and index of refraction of suitable gratings. The Figure shows a complete projection system for a lenticular film L bearing a multicolour record and passing through a gate F, the film being illuminated by an arc B with reflector H, and projected by an objective O. A prism-grating P is placed near the gate F. No alteration of the ordinary projection apparatus is necessary if the film has been taken or copied in apparatus in which the usual colour-band filter or corresponding diaphragm is laterally displaced from the optical axis ; but if this is not the case, a slight lateral displacement of the source of light may be produced by introducing a lens R, or prisms, or by a slight rotation of the plane of the gate in the projector. The Specification refers to the recording of lenticular pictures by such an optical system. Reference also is made to Specification 24276/14, [Class 97 (i)].

As described, a bowl assembly B comprises an adjustment ring 100 screw threaded to the bowl 104, a locking ring 200 screw threaded to the bowl and two rams 300 mounted 180 degrees apart on the adjustment ring at 302. Each ram 300 includes a yoke 304, Fig. 4, with a shaft 306 extendingfrom the lower end through an opening in the ring 100. The ram cylinder 308 is pivoted to the ears of the yoke at 310, and the ram piston 312 has a nose 314 on its outer end connected to it by a pin 316. The ram may be actuated by pressure fluid and returned by a spring 320, as shown, or may be double acting. The forward edge of the nose engages the teeth of a torque ring 231 which is releasably held on the adjustment ring 100 by levers 232, and is connected to the outside of the top cap 224. The upper end of the bowl is keyed to the top cap at 233 so that when the top cap is rotated the bowl is also rotated and therefore moves up or down.
