Title: Improvements in and relating to connectors, for example, for pipes or waveguides
Inventor: ROBERTS FRANK BOSTOCK
IPC: F16L37/113
Filed: 1957-01-03
Abstract: 876,394. Waveguide couplings. ERSKINE LABORATORIES Ltd. April 3, 1958 [Jan. 3, 1957], No. 292/57. Class 40(8) [Also in Group XXVIII] In a connector for waveguides the plug part 2 is positively located radially and angularly relative to the socket 1 in one locating operation by surfaces formed on both parts, the plug including a locking member or collar 7 carried thereon and movable angularly relative thereto, and both parts having co-operating surfaces whereby on angular movement of the collar 7 the parts are held in the connected position. As shown, the collar 7 has projections 9 wedge-shaped circumferentially and radially which in the coupled position co-operate with interrupted flanges 10 around the edge of a recess in the socket and with two diametrically opposed circumferentially wedge-shaped tongues 12 formed on the plug.. The collar 7 is located on the plug by a spring circlip 14 fitted in a groove in the plug and pressed against an inturned flange on the end of the collar by a spring 8. The spring 8 is attached at one end to the collar and at the other end to the plug so that it tends to make the collar turn in the direction indicated by the arrow. Shoulders 16 formed on one end of the collar engage the tongues 12 under the bias of spring 8. For coupling the two parts together the tongues 12 are made to enter slots 13 in the end face of the socket until the shoulder 15 on the collar abuts the edge of the socket. The collar is then moved axially against the spring 8 until the shoulders 16 are freed from the tongues 12 so that by rotation of the collar the projections 9 pass between the flanges 10 and projections 12 bringing the two parts of the coupling firmly together. For releasing the coupling the collar is turned in the opposite direction against the tension of the spring 8 until the shoulders 16 drop behind and are retained by the tongues 12. In a modification, the spring 8 is dispensed with and locking of the parts is effected by manual rotation of the collar 7. The plug and socket parts are welded, soldered, brazed or screwed to the waveguide sections to be joined.

Filed: 1958-01-09
Abstract: 878,411. Temperature - resposive actuating-elements. Jan. 9, 1958, No. 900/58. Class 64(2) [Also in Group XXIX] In an actuating-element, the thermal expansion of material such as paraffin wax or para-dichlorbenzene 42 forces out a pin 26 from the position shown in Fig. 3 to the position shown in Fig. 4, first by squeezing a sock portion 36 of a rubber body surrounding the pin and then, when the bottom 46 of the pin has reached the level of a flange 34, by upward pressure on the lower surface of a portion of the rubber body forming an annular plug 32 in an upper cup 14 of the casing of the element, the upward pressure being ejected through the inner part of a flange 34 between the sock 36 and the plug 32. The casing is formed by two cups 14, 16 held mouth-tomouth by a ring 20 with the rubber flange 34 clamped between them. Apart from its mouth and the hole accommodating the pin 26, the cup 14 may be unapertured, Figs. 1, 2 (not shown) or there may be holes 50, .03 inches in diameter, to take up some of the rubber of the body 32, 36, as shown in Fig. 4, on over-expansion of the material 42. when the pin 26 is fully extended. The pin is returned to the Fig. 3 position by spring. The rubber body may be formed with the plug 32 separate from the sock 36 and flange 34, Fig. 5 (not shown). For the expulsion of any trapped ambient medium, the top cup 14 may be of sintered metal powder so that pores are provided or there may be at least one passage through the wall of the cup. The top wall 24 of the cup 14 may be thin, Fig. 7 (not shown). To increase sealing pressure, the top of the plug 32 may diverge upwardly and still be enclosed by the top wall 24, Fig. 8 (not shown), or it may extend through the top of the cup 14 as in Fig. 9. Instead of having a diverging upper part ,the plug 32 may terminate in a cylindrical part, Fig. 10 (not shown) and in that embodiment a synthetic resin washer encircles the pin above the plug, to retain the rubber. In another embodiment, Fig. 11 (not shown), the plug 32 is cylindrical.

Title: Dispensing device for dispencing at least two fluids
Inventor: HOLM NIELS ERIK
IPC: A61L24/00
Filed: 1996-03-28
Abstract: A dispensing device for dispensing at least two fluids comprises a housing (12,22) of a pistol-like configuration having an integral handle (50), in which a spring-biased trigger (60) is received. Within the housing (12,22) of the dispensing device (10), two syringes (80,81) are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover (22) of the housing is closed, the motion of the trigger (60) relative to the handle (50) is transmitted to a toothed rack which cooperates with a propeller body (70) in a ratchet-like manner. The ratchet-like cooperation allows a uni-directional motion of the propeller body (70) and prevents a motion of the propeller body (70) in the opposite direction. Provided the cover (22) is not closed, the motion of the trigger (60) relative to the handle is not transmitted to the propeller body (70), and any unintentional dispensing of fluids from the dispensing device prior to the preparing of the dispensing device for use by closing the cover (22) is consequently prevented. <IMAGE>   <IMAGE>
