IPC: H02P5/74
Filed: 1967-09-14
Abstract: 1,193,664. Milling. WERKZEUGMASCHINENFABRIK ADOLF WALDRICH COBURG. 14 Sept., 1967 [17 Sept., 1966], No. 42024/67. Heading B3K. [Also in Division H2] In a milling machine, a work-piece 2 and tool 6 are adapted to be driven along perpendicular axes by D.C. motors X, Y, respectively, means being provided for determining a set angle of cut. In one arrangement, the motor X is connected to the mains to drive the feed table 3 as well as a three phase generator A which has synchronizing connections with a motor A1. The latter is coupled through gearing W with a three phase machine B<SP>1</SP> which acts as a generator and has synchronizing connections with a motor B driving the tool carrier 7. In this case, the D.C. motor Y is not connected to the mains. In this manner, the table 3 and tool carrier 7 are moved at a predetermined speed ratio in relation to each other, the angle of cut being determined by the transmission ratio of the gear W. Other angles of cut may be obtained by reversing the motor X, or by arranging that the machines A, A<SP>1</SP>, for example, rotate in opposite directions. In addition, the motor Y may be operated as the main drive, a change-over switch U being actuated so that machine B is connected to machine A<SP>1</SP>, and the machines A, B<SP>1</SP>, are interconnected for synchronous operation. The gearing W may be replaced by a gear train associated with clutches for varying the transmission ratio in accordance with a programme which is set by cam-operated switches.

[Also in Divisions E2 and F2] A leak-tight joint between a detachable component and a support member secured to a rigid wall comprises a semi-rigid sleeve or ring fastening the detachable component in the interior of the support member and a seal having at least two lips which are applied at the same time respectively against the support member and against the detachable component or the semi-rigid sleeve or ring. The support member, Figs. 1 and 3, is in the form of a bushing 3 secured by a nut 4 in an aperture in the wall 1 of a chamber containing radio-active objects, e.g. a " glove box." In Fig. 1, the detachable component is a P.V.C. glove or bellows 7 whose extremity 12 is moulded to provide a seal having a lip 13 engaging the internal surface 8 of the bushing 3 and two lips 14, 15 into contact with the bottom of an annular groove 11, of rectangular or dove-tail cross-section, formed in a polyethylene sleeve 8 which is retained in the bushing 3 by means of a bead 9 which snaps into an annular groove 10 when the glove and sleeve assembly is pushed into the bushing from the right. To replace the glove and sleeve assembly, the latter is displaced to the left, e.g. by a push-rod located in a channel 19 in the bushing, and a new assembly inserted in the bushing, the upper lip 13 of the seal in the displaced assembly being kept into contact with the bushing surface 18 until the new assembly is set in position. In Fig. 2, a transparent inspection window or a full shutter 20 is sealed to the bushing 3 by means of a three-lipped sealing ring 24 located in a groove 22 in the component 20 and is retained in the bushing by a continuous or split semi-rigid ring 23 in a channel 21 which may be formed by a collar 25 screwed on to the component 20 after the ring 23 has been fitted in position. Instead of a single lip 13, a number of lips may be provided on the outer peripheral surface of the seal 12 or 24.

Abstract: 1511149 Electrical connector BUNKER RAMO CORP 15 Oct 1975 [29 Aug 1975] 42327/75 Heading H2E A connector comprises a first connector part having a plurality of contact elements, e.g. pin 2, interengaging with a plurality of contact sockets on a second connector part, e.g. socket 1. The two connector parts are prevented from relative rotation with each other and at least one socket 1 has a constriction 4, whose configuration is complementary to that of pin 2 yet oriented at an angle to the orientation of the pin so that when the two connector parts are mated the pin 2 twists and a torqueing retentive force is exerted between the socket and the pin. In an embodiment used for supporting an IC (10) on a p.c.b. (13, Figs. 3 and 4, not shown) an insulating plate 9 (Fig. 5) is used between the IC and the p.c.b.; the upper end (12a) of the contact socket (12) is flanged and the lower end (12b) may be soldered to the p.c.b. The constriction (14) in conjunction with flange (12a) prevent the contact socket from rotating in the bore of plate 9. Fig. 5 shows two rows of contact sockets 12 on plate 9, for supporting said IC. In a modification (Fig. 8, not shown) the contact sockets (12) are shorter and the plate is constituted by the p.c.b. The end of the contact socket remote from the point of entry of pin 2 is closed with a stopper (17, Fig. 6, not shown) or by hemispheric stamping (Fig. 7, not shown) to prevent solder from entering the constriction when the contact socket is soldered to the p.c.b. (13).
