Title: Improvements in automatic or semi-automatic telephone systems
IPC: H04Q1/34
Filed: 1935-06-11
Abstract: 458,095. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, McCLEW, J. W., 27, Arlescourt Road, West Derby, and WOODLAND, C. R., 45, Warnerville Road, Broadgreen, all in Liverpool. June 11, 1935, No. 16873. [Class 40 (iv)] In a device included in a repeater for the purpose of storing incoming impulses, and retransmitting them in correct form, appropriate ones of a series of pins disposed around a plate are displaced inaccordance with the received impulse trains and act as stops for determining the number of impulses in the transmitted trains. Circuits. Line and release relays A, B energize, connecting up relay IP, and impulses are repeated to the receiving magnet RCM in parallel with relay C which holds during each train and connects up the marking magnet MKM. The magnet RCM rotates a disc R step-by-step, and the release of the magnet MKM at the end of each train allows a lever carried by the disc R to push an appropriate pin through the plate F into the path of a resetting member carried by the sending disc T. The first release of magnet MKM also connects up relay BY over off-normal contact ON (which is open only when the discs R, T are in corresponding position), and a circuit shunting relay IP is completed over the resetting member and the pin it engages (the last pin displaced during the previous call). Relay IP therefore relapses and connects up the sending magnet TRM momentarily, since the latter opens the shunt circuit, resetting the pin and allowing the sending disc T to rotate until the next displaced pin is reached. This movement is controlled by a governor and causes outgoing impulses to be sent over springs IMP. The shunt circuit for relay IP is reclosed and the sending of the next impulse train is initiated. When all the impulse trains have been received and retransmitted, relay BY is disconnected at offnormal contact ON and relays D, I are brought into circuit in readiness for the called party's reply. Should the calling party hang up prematurely, the repeater is guarded by relay BY until retransmission is complete. Mechanical details. The receiving magnet drives a ratchet-wheel 9 on a shaft 35 which carries also the pin-setting lever 39. The marking magnet upon energization moves a collar 32 so as to tilt the lever 39 away from the pins 14, and upon release allows the lever 39 to return and push the appropriate pin 14 through the plate 12. The gear-wheel 13 which drives the impulse-generating cam is itself driven by a spring 17 which is tensioned as the shaft 35 rotates, and is held by the engagement of the resetting member 24 with a displaced pin 14. The sending magnet, operating in a circuit over off-normal contacts 16, 21 and the displaced pin, moves its armature 10 so as to advance the member 24 to the right to reset the displaced pin 14, which however prevents movement of the gear-wheel 13 until the sending magnet restores on account of the stepped end of the member 24.

Title: Microwave heating apparatus
IPC: H05B6/80
Filed: 1961-05-09
Abstract: 984,424. Microwave ovens. RAYTHEON CO. May 9, 1961 [Sept. 14, 1960], No. 16904/61. Heading H5H. A microwave heating apparatus includes an enclosure at least partially separated into two regions by a partition having a microwave energy permeable portion inclined to the vertical and means for generating microwave energy which is radiated into one of the regions through its bottom wall, whence it is transmitted into the second region along a path such that it is incident from above upon material to be heated, e.g. food, located in the other region. Material 19 is heated by radiation passing through a dielectric portion 18 of a partition 16, from magnetron 22, via the region 14, which is bounded by metal portion 17 of the partition, has a corner reflecting surface 26, and is of large dimensions compared with the wavelength employed. Impedance matching with, and a desired energy distribution over, the body 19 can be obtained by adjustment of the paddle 27, and the height of the metal portion 17 of the partition. In a modification (Figs. 3 and 4, not shown), a metal partition extends wholly across the enclosure, and has a central aperture covered with a dielectric sheet. A waveguide may be employed to couple the energy into the region 14, and the dielectric portion of the partition can, in the absence of fumes from the heated material, be dispensed with.

Abstract: 474,472. AttachÚ-case &c. fastenings. CHENEY, C. W. June 18, 1936, No. 16933. [Class 44] In fastenings for attachÚ cases &c., in which a member on one part, such as the lid, enters a casing on the other part and is retained therein by a pivoted catch or catches releasing means are pro vided which release the catch or catches and posi tively initiate the dis engagement of the fasten ing member. Fig. 2 shows a form in which a plate a<2> attached to the lid has a tongue with upstand ing rib a<3> adapted to enter the open end of a casing c on the body of the attachÚ case &c. The casing houses a sliding plate f carrying pivoted catches y, h, which, when raised clear of the opening in the casing, are biassed to the release positions by springs i. The slide f can be operated by a member e with finger piece e<2> rotatably mounted on a fixed stud and having a pin c<3> engaging a slot f<5> in slide f. A spring j<4> bears against pin e<3> and serves to complete the movement of the slide to each of its extreme positions by passage of the pin over a deadcentre position. When the part a<3> is inserted in the casing it engages a transverse flange f4 on the slide to move the latter inwards, spring j<4> completing the movement. As the catches g, h enter the casing the walls of the casing move the catches into engagement with rib a<3>. When member e is operated to raise the slide and effect release, flange f<4> positively ejects member a<2>. A cam may be used instead of springs i to move the catches outwards. A single catch pivoted to move transversely to the plane of the plate a<2> may be used.
