Title: A device for stabilising a baby carriage or the like
IPC: B62B5/04
Filed: 1945-12-27
Abstract: 602,852. Perambulator stands. BERNER, C. A. O. Dec. 27, 1945, No. 35006. [Class 79 (iii)] [Also in Group XXXII] A device for preventing the tipping-up or other undesirable movement of a non-folding perambulator comprises a support member which is pivotally mounted on the chassis so as to be capable of lying in a place substantially parallel with the chassis or of being moved to an operating position in which it lifts the wheels of the perambulator from the ground, an overcentre spring 12 being provided for urging the support member into both its operative and inoperative positions. In the arrangement shown a longitudinal frame member 4 at each side of the carriage is connected by U-shaped brackets to the axles 3. A member 7 is pivoted at 6 to the front end of each member 4 and has detachably connected thereto an extension member 9 ; the members 9 on opposite sides are connected between the front ends of the members 4 and bars 11 secured on the members 7. Normally, the support comprising the members 7, 9 and the cross-bar 10 is held by the springs in a horizontal position adjacent the members 4. When pressure is applied to the bars 11, the support moves about the pivot 6, thus extending the springs 12 until they snap over dead-centre and the support takes up a position in contact with the ground. One support member may be provided at each end of the perambulator. The Provisional Specification describes also the following features: (1) the support is held in the operative position by the engagement of notches in the support with projections forming the anchorage for the springs ; (2) the front wheels of the carriage are carried in pivoted U-shaped supports corresponding to the members 7, 9 described above, the movement of the support to bring the wheels from their normal propelling position to the position in which the wheel base is extended being controlled by over-centre springs ; (3) the front wheels are carried by a subsidiary frame which is slidable longitudinally in the main chassis and is held in the normal propelling position by overcentre springs, means being provided for sliding the subsidiary frame so as to extend the wheel base.

Filed: 1922-12-22
Abstract: 204,978. Ballance, A. B., and Anderson, W. T. Dec. 22, 1922. Electrically tripped and released switches; clockwork actuation. -At a predetermined time a solenoid 12 is energized to withdraw a spring- controlled detent 8 from a plunger 11 which falls and closes a circuit at 7; at a second predetermined time a solenoid 13 is energized to raise the plunger 11 into its original position. Also a strip 27 carried by the plunger 11 opens the circuits of the solenoids 12, 13 at 28, 29 after they have operated. The energization of the solenoids 12, 13 is effected by a clock-actuated rotating cylinder 17 which makes permanent contact with a brush 14 and temporary contact at predetermined times with brushes 15, 16 which are normally held away from the cylinder 17 by adjustable insulating rings 18, 19 provided with holes 20, 21. Adjustment of the cylinder 17 is effected by moving it axially out of engagement with the clock mechanism. The solenoids 12, 13 may be actuated at any time independently by hand-operated switches 30, 31.

Abstract: 201,602. Milne, J. S. March 8,1922. Kinematograph apparatus.-To eliminate flicker in an intermittent feed projector, the screen is illuminated by an auxiliary light beam during the periods of movement of the film, the intensity and colour of the auxiliary beam being regulated to correspond to those of the projecting light. The auxiliary light may be derived from the projector or from a separate source. Figs. 2 and 4 show an auxiliary lantern H, which is attached to the projector A and comprises condensers N, S, reflector M, and projecting lens T. The lantern H may also be provided with an adjustable erecting lens. The beams from the lanterns A, H are projected alternately by a rotary shutter K, Fig. 6, having central masking portions for the projection beam and annular masking portions for the auxiliary beam. The masking blades may be formed of uncoloured glass having a rippled surface. The intensity and colour of the auxiliary light are adjusted by slides inserted in the lantern H. In a modification, Fig. 11, the auxiliary light is derived from reflectors b on the shutter arranged, in conjunction with a fixed reflector, to project the auxiliary beam during the periods of observation of the projection beam.

A valve (114), Fig.7 (not shown), is operable in conjunction with the clutch to hydraulically connect units 3 and 4, so that, with the clutch engaged, both units 3 and 4 operate as pumps, or as motors, and with the clutch disengaged, one of the units can be operated as a pump or motor, or both units can be operated in a closed circuit as a hydrostatic transmission (see Division F2). Clutch 19 is operated by a lever 32 acting through slider 30 and rods 28 to engage splines 23 with splines 21. A bearing 24 within the clutch sleeve supports shaft end 25. Alternatively, the shaft end may be supported by a bearing in an enlarged end of shaft 12, which is splined for engagement by a clutch sleeve on shaft 18, Fig.2 (not shown).

Abstract: 798,744. Aircraft feel simulators. HOBSON, Ltd., H. M., WESTBURY, R., and SMITH, C. P. Oct. 21,1955 [Dec. 7, 1954], No. 35408/54. Class 4. An aircraft hydraulic feel simulator of the kind comprising a hydraulic jack coupled to the pilot's control member to produce a resistance to movement determined by the hydraulic control pressure in the jack, a pump for supplying liquid under pressure to the jack, and a control valve actuated by an airspeed responsive device and movable from a neutral position to place the jack into communication with the pump or exhaust to vary the control pressure in the jack, comprises also a spring-loaded accumulator connected to the conduit by which pressure liquid is supplied to the control valve downstream of a non-return valve in the conduit, the accumulator being normally held inoperative by the supply pressure but serving, in the event of failure of the supply and closure of the non-return valve, to supply liquid under gradually diminishing pressure to the jack through the control valve. The simulator shown in Fig. 2 is the same as that described with reference to Figs 1 and 8 in Specification 734,437, except that a non-return valve 25 is provided in the inlet 29 from the pressure supply line to the control valve, and that the pressure supply port 33 surrounding the valve communicates with an accumulator 45 comprising a cylinder 46 containing a piston 47 loaded by a spring 48. Should the main pressure supply fail while the pilot is engaged in a manoeuvre involving high feel, the valve 25 closes, and the liquid in the accumulator supplies the jack under diminishing pressure as the spring 48 extends, whereby the feel force diminishes gradually, and the change in feel does not cause the pilot to make a sudden control movement. A relief valve may be connected between the hydraulic control pressure in the jack and exhaust, which valve may only open when the main supply pressure fails. According to the Provisional Specification the accumulator may be loaded by compressed air. Reference has been directed by the Comptroller to Specification 734,437.
