Filed: 1985-12-20
Abstract: In response to interengagement between a contact assembly (130), (Fig. 10), on the vehicle and a charging head (12), (Fig. 4), charging current is supplied to the charging head for recharging the vehicle's battery. The interengagement operates a microswitch (187), (Fig. 16A), on the vehicle whereby if a charge level monitor (208) indicates that recharging is required, a vehicle computer (204) energizes a relay (212) so that a signal is sent from the battery (206) via the charge head to unblock safety switching means (214) whereby the charging head is supplied with charging current and charging is effected under control of a current limiter (210) on the vehicle, The interengagement also operates a microswitch (94) at the charge head, in response to which communication between the vehicle computer (204) and a charge head computer (205) is established. The vehicle drive system may be computer controlled for indexing of the vehicle between charge heads. Interengagement of the vehicle contact assembly and the charge head is facilitated by providing guide members (196), (198), (Fig. 10) on the vehicle and providing a spring- biased self-aligning mounting for the charge head (Figs. 5, 6) which allows the head to a rise and fall on a parallelogram linkage, b rotate about a vertical axis, and c to move horizontally laterally of the vehicle's direction of advance. During the interengagement cams 36, 152, on the charge head and vehicle respectively, lift cover plates 134, 50 to expose electrical contacts on the vehicle contact assembly and the charge head. <IMAGE>

Patent GB-2201931-A (GB)
Title: Ornithopters
Inventor: FISHER WILLIAM THOBY
IPC: B64C33/02
Filed: 1987-01-07
Abstract: A flapping wing aircraft has wings which flap, in unison, about hinges 24 and are also free to move in another plane about a transverse hinge 21. Springs or/and other elastic means exert some control over both movements and the reciprocating drive rod 33 also tends to actuate the wing movement in pitch as well as in flapping. The wings produce thrust during the downstroke by tipping or pitching of the wings relative to the high pitch-inertia body. A toggle link assembly 42, 43 with torsion bars 52 and drive rod 33 with centre line aft of transverse hinge line 21 are employed. Authoritative aileron control is obtained by a linkage with a floating arm pivot (85 86) (Fig 3) and links (83 84) which together compensate for the effects of wing flapping and wing pitching on the transmission of pilotage movements to the aileron control surfaces. Each wing may be fitted with a flapping outer wing which is power operated to flap to a greater angle relative to the body than the inner wing and this outer portion may be fitted with a plain flap spring biased to the central position. <IMAGE>

IPC: G01M3/04
Filed: 1987-11-13
Abstract: A pipe 12 for testing is supported by a base 11 fixed to the ground and its ends are adapted to be sealingly engaged by clamping members 17, 18 carried by a wheeled base 13, 14, 15 mounted on tracks 16 laid on the ground. A coil spring (30) connects the base (13) to a suitable location on the tracks (16). The clamping member (17) is fixed a support bracket (19) of base 13 and the clamping member (18) is mounted by a ball and socket joint on a ram (20) fixed on a support bracket (21) of base 13. The clamping member (17) has a through-bore (23) in fluid communication with a reservoir (23a) and the clamping 18 has a bore (25) in fluid communication with the pipe (26) which is open to the air. With pipe 12 on base 11 ram (20) is actuated to push the clamping member (18) against one end of the pipe (12). Due to the inertia of pipe continued actuation of the ram (20) after contact with the pipe causes the clamping member (18) to remain stationary and the chassis (13) to move along the tracks (16) against bias of spring 30 until the clamping member (17) contacts the other end of the pipe (12) so as to firmly clamp the pipe (12) between the members (17, 18). Water is pumped from the reservoir (23a) so as to overflow the pipe (12), the air and excess water escaping via the bore (25). The pressure of water in the pipe is about 20 psi (1.38 x 10<2>kPa) and maintained for about 30 seconds. Any leaks or porosity in the pipe can be visually determined. <IMAGE>

Title: Recovery of desorbate
Inventor: PEINZE REINHOLD
IPC: B01D5/00
Filed: 1988-10-25
Abstract: In order to be able to recover the desorbate of high-boiling point organic substances that have a tendency to form mists and/or low-boiling point organic substances that tend to decompose, such as halogenated hydrocarbons, and which occur during the recovery of the charged sorption agents during desorption, it is proposed that the desorbate be condensed in a direct heat exchange (8), with the desorption gas that is to be cooled below the condensation temperature of the desorbate being brought into contact with recycled desorbate that has been supercooled sufficiently beneath the condensation temperature of the desorbate, and thereby cooled. To this end, the recycled desorbate is removed from a tank (10), cooled in a heat exchange (11) to a temperature below the condensation temperature, and moved into the direct heat exchanger (8) with the help of a pump (12). Within the heat exchange (8) the desorption gas which is to be cooled and which originates from the desorping adsorber (1), is propelled by a blower (6) and cooled down to the desired temperature to separate the desorbate.
