Abstract: 733,347. Metal-working presses. EVANS, F. A. May 22, 1953 [Feb. 23, 1952], No. 4814/52. Class 83 (4). Tempering blanks.- Automatic feed mechanism for a power press, guillotine, automatic welding machine, or a bottling machine, having a crank-shaft adapted to be clutched to a continuouslydriven fly-wheel, comprises means for picking up a component at a point remote from the press tools and transferring it to the tools, means operable after the component has been fed to the tools for energizing power actuator for engaging the clutch which sets, the press in motion and means controlled by a member associated with the crank-shaft of the press for stopping the feed mechanism if the press, is not set in motion on energization, of the power actuator or is,.out of synchronism with the feed mechanism. The feed mochanism is generally of the kind, described in Specification 724,085, in which an oscillating arm 22, Fig. 3, has a pair of jaws 25, operated by a compressed air motor 28, which pick up a component from an intermittently rotating feed-table 30 and transfer it to the press die. The arm is oscillated about a vertical pivot 21 by a rod 20 coiinected to an oscillating disc 19 driven through a link 17, Fig. 1, by a rotating disc 15 on the output shaft of a gearbox 13 which is driven through a manually controlled clutch and a variablespeed V belt-drive 12 by an electric motor 11. The arm is also rocked about a horizontal axis at the end of each of its oscillating movements by means of a lever.23 co-operating with cams 24 on the disc 19. The air motor 28 is controlled by a valve 53 actuated by a cam 54 on the disc 19. After depositirig the component in the die, the arm 22 is returned and during this movement valve 50, is opened by a cam 51 on a disc 15<SP>1</SP> mounted on the output shaft of the gear-box 13, and compressed air is supplied to a motor 32 which actuates the one-revolution clutch of the press. When the press crankshaft rotates, a cam thereon actuates a valve which causes the motor 32 to be de-energized so that only one revolution is performed. During the upward movement of the press ram, a pair of valves controlled by a cam on the press crank-shaft are opened to supply air to nozzles 411, 421, Fig. 3, which blow away swarf and eject the finished component. A guard, preferably of transparent plastic, may be fitted to the press. Limit switches operated by cams on the disc 151 and on the crank-shaft of the press are provided in the circuit of the electric motor driving the feed mechanism whereby the latter is stopped if the feed mechanism and the press are out of synchronism. The Provisional Specification also refers to the oscillating disc 19 being driven by a double-acting pneumatic motor instead of the electric motor.

Title: Improvements in or relating to microwave switching arrangements
IPC: H04B1/52
Filed: 1960-02-16
Abstract: 889,468. R.F. couplings. TELEFUNKEN G.m.b.H. Feb. 16, 1960 [March 21, 1959], No. 5425/60. Class 40(7). [Also in Group XL(b)] A microwave switch comprises a circulator having an adjustable short-circuit in the form of a movable conductive member in at least one branch. In the embodiment shown, two such switches, comprising ferrite 4-port circulators Z 1 , Z 2 , Fig. 1, are used to selectively connect two T.R. sets FG 1 , FG 2  (one of these being a standby) to a comon aerial A. The set FG 1  comprises a transmitter S 1 , using a frequency f 1 , and receiver E 1 , using a frequency f 2 , connected to the circulator Z 1  in the usual manner so as to decouple transmitter and receiver. The transmitter and receiver S 2 , E 2  of set FG 2  are connected in a similar manner to the circulator Z 2  and the remaining terminals of Z 2  are connected to the circulator Z 1  and to a matched load R. During operation of the set FG 1  the conductive members of adjustable short-circuits K 1 , K 2  are in their withdrawn, open-circuit, positions and have no effect. When it is desired to operate the standby set FG 2  the conductive members are moved to short-circuit branches L 11 , L 31  and wave-energy in these branches is reflected at the short-circuits. Thus the aerial A is coupled to the second circulator Z 2  and the second circulator is coupled to the aerial, the two circulators being effective to de-couple transmitter S 2  and receiver E 2  in the usual manner. The circulator branches connected to the transmitters and receivers may incorporate band-pass filters of the multi-cavity type and the movable members of the adjustable short-circuits may be arranged to de-tune a filter cavity in each of the branches L 11 , L 31  in order to render the filters reflective. In the modified arrangement of Fig. 3, receivers and transmitters S 1 , S 2 , E 1 , E 2  of T.R. sets FG 1 , FG 2  are connected through multi-cavity filters F 1 , F 3 , F 2 , F 4  to two branches of a single circulator, each common to the transmitter and receiver of a T.R. set. The separate branch of each transmitter and each receiver are made one quarterwavelength long between each filter and the common junction. In this arrangement it is only necessary to have two short-circuits either in the filters of S 1  and Eg or of E, and S 2 .
