Title: Video connector having an internal male/female jumper
Inventor: BAKER ROBERT WILLIAM
IPC: H01R13/516
Filed: 1993-08-26
Abstract: A computer cable connector 20 includes coaxial terminals positioned in apertures 40 of an electrical housing 30 and receiving coaxial conductors 85 from a cable, while signal conductors 86 from the cable are terminated to id contacts in the housing. A male/female adapter 62 is positioned in an aperture of the housing 30 thereby providing a rear socket portion for mating with a complementary connector 100 attached to an auxiliary cable. The housing and the adapter are overmoulded to form an outer insulating housing 22 having an L-shaped receiving section 90 for receiving the connector 100. The main connector 20 can be plugged into a computer port 2, and an auxiliary cable can be connected and disconnected to the adapter 62 via the connector 100 thereby interconnecting the cable with the signal contacts 12 of the computer port. The adapter 62 projects rearwardly of the coaxial and signal contacts and the complementary connector receiving section 90 transversely overlaps the coaxial and signal conductor terminating area, resulting in space savings. <IMAGE>
Patent GB-940346-A (GB)
Abstract: 940,346. Photogrammetric apparatus, CARL ZEISS-STIFTUNG, [trading as C. ZEISS [Firm of]]. March 7,1960 [March 6,1959],No. 7909/60. Heading G1F. In a photogrammetric plotting apparatus, two measuring images are observed by a stereoscopic visual system containing reference marks, and two displacing systems for producing relative displacements between said reference marks and said measuring images are controlled by the displacements of a cross-slide; recording means are provided for recording the displacements of the cross-slide, and also for recording the said relative displacements. In the form shown, the carriage 2 cah be displaced perpendicular to the plane of the paper, along guides 1, by means of hand-wheel 4. Carriage 7 moves on carriage 2 in the directions of arrows 6 by means of spindle 8. Guides 1 can be displaced vertically by spindles 11, 12, and the displacements in the three dimensions are recorded by counters 9,10,14. Two transmission levers 16, 16<SP>1</SP>, centrally supported by ball joints 17,17<SP>1</SP>, which link the movements of carriages 7 and 21, are connected at their lower ends in ball sockets 15, 15<SP>1</SP> in carriage 7. At their upper ends they are connected in similar ball sockets 19 to two carriages, 21 on the right of the drawing and an identical one on the left. Carriage 21 can be displaced in two directions at right-angles by moving in guide 22 which itself can move along guide 24 Carriage 21 also carries a switch-box 25 having an upper part 27 separated from the lower part by a shaft 26. Engaging in a groove 28<SP>1</SP> in the upper part 27 is a pin 28 connected with a nut 32 on a carrier 31. Sliding along guides in the carrier 31 is a further carrier 35 supporting an aerial photograph 36, which is viewed through the right hand part of a stereoscopic viewer 37. (This part of the apparatus is all duplicated on the left hand side, as shown.) Carrier 31 can be driven by a motor 60 and spindle 30, and carrier 35 can be driven at right-angles to carrier 31 by motor 39 and spindle 38. Both these movements have counters 41, 42, and can be controlled by respective hand-wheels 50, 51. If carriage 21 is displaced towards the right, for example, shaft 26 carrying upper switch part 27 also moves to the right. The pin 28 tilts the upper part 27 so that the right-hand poles 29 close, so energizing motor 60. This moves carrier 31 (and therefore nut 32) to the right, so that the switch poles 39 open once more, and interrupt the motor circuit. Movement of carriage 35 perpendicular to the plane of the paper is similarly controlled by a switch 40 acting in the same way as switch 25. The apparatus is intended for map-plotting, i.e. contours, but may be used as a comparator by rendering the following up motors 60 inoperative.

Title: Vangs
Inventor: VINCENT RAYMOND
IPC: B63H9/10
Filed: 1997-04-23
Abstract: A vang for producing a desired tension in the mainsail of a yacht employs, in association with a multi-sheave block and tackle system 91, a valve releasable, variable length, pressurized gas spring strut 11. Operation against a spring pre-load of the control valve of the strut 11 by application of a force thereon via the block and tackle system 91 enables the gas spring strut 11 to be released from the length at which it is currently held locked, by reason of closure of the control valve, for such extension or contraction as may be required to produce a desired force on the main-boom 113 and a consequent tension in the leech of the mainsail. Immediate actuation of the valve of the gas spring strut, without the necessity of having to overcome spring pre-load using the multi-sheave and tackle system, is effected by means of secondary valve actuation means 21. This allows the strut 11 to expand to its maximum length to allow the boom 113 to swing upwardly, with the mainsail threreby being freed from tension from the vang and loosing its aerodynamic contour.

Title: Hydrocarbon gas processing
Inventor: CAMPBELL ROY E
IPC: F25J3/02
Filed: 1995-11-06
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is divided into first and second streams. The first stream is cooled to condense substantially all of it and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a first mid-column feed position. The second stream is expanded to the tower pressure and is then supplied to the column at a second mid-column feed position. A recycle stream is withdrawn from the tower overhead after it has been warmed and compressed. The compressed recycle stream is cooled sufficiently to substantially condense it, and is then expanded to the pressure of the distillation column and supplied to the column at a top column feed position. The pressure of the compressed recycle stream and the quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered.
