Patent GB-1287140-A (GB)
Title: Vehicles having hydropneumatic suspension systems
Inventor: PANHARD JEAN
IPC: B60G11/56
Filed: 1969-11-12
Abstract: 1287140 Vehicle suspension SOC DE CONSTRUCTIONS MECANIQUES PANHARD & LEVASSOR 12 Nov 1969 [13 Nov 1968] 55438/69 Heading B7D [Also in Division F2] A hydropneumatic vehicle suspension spring consisting of an hydraulic piston-and-cylinder unit 8, 9 in communication with at least one hydropneumatic accumulator 20, 21 has means 22-41 for automatically recharging the cylinder 9 with liquid whenever leakage occurs. A valve member 24, controlling liquid flow between the cylinder 9 and a source 27 and an outlet 28, is normally held in a closed position by springs 39-41 which are selected so that, over a certain range of piston movement, they balance the force of the liquid acting on the member 24. As soon as leakage of liquid occurs, the spring force overcomes the liquid force, and moves the valve member 24 to connect the cylinder 9 with the liquid source 27. Liquid then flows into the cylinder until the liquid force again equals the spring force thereby returning the valve member 24 to its closed position. The cylinder 9 is in constant communication with the accumulator 21 but the accumulator 20 comes into operation only after a predetermined rise in pressure in the cylinder. The spring force may be varied to omit different road conditions. This causes the amount of liquid in the cylinder, and thus the ride height of the vehicle to change. In Fig. 3 (not shown) two systems (31a, 31b) of springs act on the valve member 24 and are controlled by a pilot pressure supplied from valves operated by a hand wheel. For cross-country riding the pilot pressure is large and both systems (31a, 31b) are in operation, and the wheel 4 moves away from the vehicle frame. For road riding a smaller pilot pressure puts the system (31b) out of operation, the other system (31a) alone providing the spring force. With a zero pilot pressure, neigher spring system acts on the valve member 24 and so the cylinder 9 is connected to the outlet 28. The wheel rises towards the frame. This movement is aided by liquid supplied from an admission device (Fig. 7, not shown) to the piston rod side of cylinder 9. The pilot pressure at its maximum acts directly on the valve member 24 thus connecting the cylinder continuously with the source 27 and raising the vehicle to its maximum height. Individual wheels or sets of wheels may be supplied with different pilot pressures.

Filed: 1973-11-29
Abstract: 1443761 Hair dryers SCHICK INC 29 Nov 1973 [22 Dec 1972] 55461/73 Heading A5R A hair dryer 20 comprises a head mounting assembly 24 pivotally supporting a head assembly 22 which defines a region for receiving part of a user's head, said head mounting assembly 24 having an elongated conduit passing therethrough for directing air to a substantially annular plenum having means for directing air towards said region, and forming a continuous loop comprising a straight first portion 64 within the head mounting assembly and a C-shaped second portion 34 in the head assembly, means being provided for maintaining the two portions in pivotal alignment, counterbalancing means maintaining the head assembly 22 in any position relative to the head mounting assembly 24. Head mounting assembly 24 is pivoted on a base 28 so that the dryer is foldable. The two portions 64, 34 of the plenum are held in alignment by a bushing 70 which is secured to plenum portion 64 by resilient fingers (78) (Figure 2, not shown) carrying detents (80) which engage a flange (82) in plenum portion 64, and by a keying boss (103) (Figure 6, not shown) which extends into a locking notch (104) in head mounting assembly 24. The counterbalancing means comprise a spiral spring 74 the outer end of which has a slot (100) (Figure 9, not shown) engaged with the end 96 of a bracket 90 which is secured to the bottom wall 88 of head assembly 22. Spring 74 is coiled around, but not fixed to, a spring mounting spool 72 which is integral with bushing 70 and is thus secured to head mounting assembly 24. Keeper flange 73 retains spring 74 on spool 72. Spring 74, which may typically be made of two layers of stainless steel strip, is formed into a tightly wound spiral about 1 inch in diameter exerting an almost constant pull of about 7¢ lbs as it is unwound. When the dryer is completely folded, spring 74 is maximally unwound as shown in Figure 3, the unwound part being constrained to a fixed radius by two spring guides 110, thus ensuring that the force of the spring is circumferential. As the appliance is unfolded, spring 74 coils up on spring mounting spool 72 until the fully unfolded position shown in Figure 4 is reached. A counter balancing unit may be fitted at one or both ends of plenum portion 64, and, so that one type of bushing 70 is usable in either position, it is made symmetrical about the line C (Figure 4). The two spring guides 112, which serve no purpose in the position illustrated in Figure 3, come into use instead of the spring guides 110 if the bushing it fitted at the opposite end of plenum portion 64.
