Title: Improvements in or relating to party-line telephone systems
IPC: H04Q5/20
Filed: 1927-09-01
Abstract: 294,095. Hasler Akt.-Ges. vorm. Telegraphenwerkstõtte von G. Hasler. July 16, 1927, [Convention date]. Manual exchange party-line systems. - In a party-line system employing step-by-step selectors S, calling and clearing signals to the exchange operator are controlled by a differential relay DR which is operated over earth connections at a substation when a call is initiated and when the subscriber hangs up. The operation of key RT by a calling subscriber completes a circuit from earth over normal contact 1 of the selector S, relay RA, lead a, and upper windings of relay DR which energizes and completes circuits for relay B and call lamp AL. Relay B locks over contacts of relay C1, lights busy lamp BL and connects the lower windings of relay DR to lead b. The windings of relay DR are thus energized in series over leads a, b, and selectors S and busy signals Bz at all the substations, and relay DR being differentially wound releases. The relays RA which control the speaking and ringing circuits are disconnected at selector contacts 1 at all other substations, thus preventing any interference with the call. Relay RA at the calling station, however, remains operated over its own contacts. When the answering plug As is inserted, sleeve relay C1 operates, releases relay B and lamps AL, and energizes relay C2. If the wanted party is on the same line, plug Ws is inserted into jack WK whereby relay W is energized over the ring circuit and the dial J is connected in series over leads a, b with selector windings S. The operation of the dial causes the selector at the wanted station to close at its contacts 2 the circuit of relay RA. The plug Ws is then withdrawn and ringing-current from the cord-circuit associated with plug As passes over contacts of relay RA to the wanted party's bell. The lifting of the receiver connects it to line and connects up the local-battery microphone M. When the two parties hang up, an earth connection over contact 6 of the switch hook unbalances relay DR which again operates and energizes relay B, which opens a loop to give supervision at the cord circuit. When plug As is withdrawn, relay C1 releases and disconnects C2, which however is slow to release so that a circuit is closed for relay W which releases relays B, DR, RA and selectors S.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1956-07-25
Abstract: 833,751. Photographic shutters. GAUTHIER G.m.b.H., A. July 25, 1956 [Aug. 26, 1955], No. 23028/56. Class 98(1) In order to allow a supplementary opening of the shutter blades (e.g. for view finding) independently of the usual master member spring, the master member comprises two relatively movable parts arranged to be non-positively connected to one another, one part is adapted to be actuated by the master member spring and the other part is connected to the usual blade ring and, when the shutter has been set, is movable relatively to the first part through a limited amount to open the shutter blades. As shown, the master member comprises two discs 13 and 14, Fig. 3 (not shown) of which disc 13 is freely rotatable on a spindle to which the disc 14 is attached. The shutter is set by rotating the spindle counterclockwise, thus moving the disc 14 so that a projection 14c thereon abuts a lug 13b on disc 13 whereupon the two discs rotate together to tension a spring 22 engaging a lug 13c on disc 13. The shutter is held in the set position by the engagement of a latch 10a with a lug 13a on disc 13, but the shutter blades may be opened by rotating the spindle clockwise until the lug 14d on disc 14 abuts the lug 13a on the disc 13, this limited rotation being sufficient for the latch 17, pivoted to disc 14 and embracing a pin on the blade ring 3 to move ring 3 into the "blades-open" position. Release of the spindle allows a spring 20 to rock the ring 3 and thus action the disc 14 to the set position. An exposure is effected by depressing trigger 7 to release the latch 10a whereupon the discs 13, 14 rotate together in the clockwise direction so that latch 17 reciprocates the ring 3 to open and close the shutter blades.

Abstract: 295,398. Clement et Rochelle, (Assignees of Clement, R. M., and Rochelle, M. R.). Aug. 11, 1927, [Convention date]. Springs, arrangement of and mounting bodies and undercarriages on; guiding vertical play; lateral canting, preventing.-In a motor vehicle suspension in which each wheel axle is rigidly connected with a slide block vertically movable on a guide pivoted on the chassis, the springs are disposed transversely on the chassis and the ends act on the slide-blocks but may move thereon; the driving wheels may be in front of the vehicle and act as the steering wheels. The chassis may comprise channel members supported transversely by tubes, the front end of the members being connected by a box member 6 to which a transverse. spring 3 is bolted. Two transverse tubes 35, 36 of which 36 is fixed to the chassis, have their ends supported by stay tubes 51, 52 and these ends form pivots for a frame 21, 22 on the members 21 of which slides the support 20 and axle 17. The bottom member 22 of the frame is extended to form an arm 37 for the track rod 14 and a rod 38 connected to the steering column. The transverse leaf spring 3 enters a recess 25 in the support 20 and may bear on the latter through rollers. The rear wheels Fig. 8 are mounted on an axle 54 supported in roller bearings 56 and the drive is transmitted to them through a flexible transmission or universal joints 62, 63 and a telescopic rod and tube 64, 65. The support 55 is mounted slidably on members 21 carried by transverse tubes 67, 68 and stay tubes 70, 71 and lies under the influence of a transverse leaf spring 4 secured at its middle point to the back axle gear casing 8 which is fixed to the frame. The spring support for both front and rear transverse springs is above the wheel supports and as the chassis and consequently the centre of gravity is also below the spring support, the vehicle body cants towards the centre when turning on curves. The springs may be used in combination with coil springs on the rods 21. Rubber rings or coil springs may be mounted on the rods 21 to prevent damage in the event of the breaking of the suspension springs. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the longitudinal arrangement of the suspension springs. This subject-matter does not appear in the Specification as accepted.
