Title: An apparatus for separating and, if desired, sorting flat objects
IPC: B65B35/08
Filed: 1953-02-13
Abstract: 720,707. Separating and sorting coins. SCHUITEMA, A. Feb. 13, 1953, No. 4118/53. Class 27. [Also in Group II] Apparatus for separating and sorting flat objects of circular, oval, or other shape, such as coins or pharmaceutical tablets, comprises a horizontal rotary feeding plate 1, a rotary incised separating disc 4 which partially overlaps the plate 1 and is partially surrounded by a ledge 13 and a stationary plate 12 which lies under the disc 4 and has a series of apertures 16-20 of progressively increasing width. The plate 1 and disc 4 rotate in opposite directions so that their overlapping portions move in the same direction and the plate 1 is arranged to rotate more quickly than the disc 4 so that the coins are initially pressed into the incisions until an overlapping portion 21 of the ledge 13 is reached. The wedge shape of the portion 21 ensures that only one coin is carried round in each incision by removing any coins that have not lodged against the leading wall of the incision. The trailing wall of the incision then forces the coin against the ledge 13 until it meets an aperture 16-20 which is large enough to allow it to tilt and fall down a discharge funnel past an electric contact or a photo-electric cell operating counting means. Both walls of the incisions are non-radial, with the leading wall undercutting the disc circumference; the leading wall may be curved concavely and may have recesses to accommodate three coins at a time. The counting of the separated coins may be done separately by an incised separating disc feeding the coins to a discharge funnel having counting means operated electrically or by a photo-electric cell or by mechanical means that automatically stop the separating disc when a predetermined number of coins have been counted.

Patent GB-1446691-A (GB)
Title: Telephone exchanges
IPC: H04Q3/62
Filed: 1974-01-31
Abstract: 1446691 Telephone exchanges STANDARD TELEPHONES & CABLES Ltd 31 Jan 1974 04567/74 Heading H4K A manual exchange, e.g. a PMBX employs a crosspoint matrix at each crosspoint element of which is a relay in series with a diode, the junction therebetween being connected to a hold wire via a contact of the relay, the arrangement being such that a crosspoint relay is operated in response to manual actuation of row and column marking keys is maintained over a path independent of the keys in a manner such as to reverse bias the associated diode so that that crosspoint cannot be taken into use for a second connection, and is automatically broken down when one of the subscribers releases. As described the crosspoint elements are sealed contact reed relays. The ringed crosses shown are lamps or light emitting diodes associated with extensions, connectors and exchange lines. When due to a call initiation an exchange line or extension lamp is lit, a buzzer or bell sounds and the operator responds closing a locking key SWE1 to SWE8 associated with the exchange line or a non-locking key (not shown) associated with the extension, switch SW1 being automatically set to connect to the selected line. The operator ascertains the connection required and presses a non-locking key or a locking key associated respectively with the called extension or connector to be taken into use. In the case of an incoming or outgoing main exchange call the appropriate crosspoint responds, the connection is complete and the operator withdraws from the connection by releasing the locking key. In the case of an internal call a cross-point of the access half A of a local connector responds when the locking switch SWC1 to SWCN associated with the selected connector is operated and the operator operates the non- locking key associated with the called extension thus operating a crosspoint of the connect half C of the connector before releasing the non- locking key. A feed bridge (Fig. 3, not shown) is detailed which supplies ringing signals and causes release of the crosspoints relays involved when either party releases. A tone is introduced on the line if the operator remains in circuit while both parties are off hook. Under fault or night service conditions the operator's set connects automatically to the first exchange line.

Title: Means for reducing leakage inductance in magnetic antennas
IPC: H01Q7/06
Filed: 1955-02-17
Abstract: 765,171. Aerials; radio direction-finding. BENDIX AVIATION CORPORATION. Feb. 17, 1955 '[March 22, 1954], No. 4821/55. Class 40(7) The invention relates to magnetic aerial systems comprising a rotor consisting of a pick-up coil 2 wound on a high permeability core 1 which is surrounded by a plurality of high permeability pole pieces 3 separated from each other by equally dimensioned air gaps 5. Each pole piece is symmetrical about a respective vertical plane and is in low reluctance relationship with a bar (6, 7, 8 or 9) of high permeability material extending radially from the rotor. Such an aerial system may be used for direction-finding by the null method or may be aligned for maximum signal strength for communication purposes. It is a limitation of this type of aerial system that the leakage flux 15 through the pole-pieces of the bars in minimum pick-up relationship to the rotor increases the inductance of the coil and im pairs the match between the coil and its associated timed circuit in the transducer. The increase in inductance is not constant but depends on the rotor position relative to the air gaps 5. It's variation masks the direction finding null by rendering its sides less steep and may cause error in bearing determination. According to the present invention means are provided increasing the reluctance of the pole pieces to the leakage flux in order to reduce possible error to an unobjectionable level. One such means comprises a short conductive turn 16 arranged round each pole piece in its plane of symmetry. Preferably the 'turn 16 is formed of flat copper strip let into a recess or groove 17 formed in the pole piece. It is stated that a single turn 16 is usually sufficient but that more than one turn on each pole piece may be used provided that the distances between turns and the distances between the outside turns and the air gaps 5 are made equal. Means are shown in Fig. 4 for holding the inner ends of the bars in close relationship with the pole pieces. Each bar is provided with a U-shaped spring 13 attached to its lower surface and mounted to pivot on a pin 18 below collar 20. The pin 18 extends upwards into a bore 19 in the lower part of the bar. Thus the bar is capable of angular adjustment about pin 18 while its overhanging face 12 is maintained in close contact with the horizontal part 11 of the outer end of the pole piece 3. Specifications 719,526 and 765,172 are referred to.
Patent GB-581162-A (GB)
Title: Radio distance meter
IPC: G01S1/02
Filed: 1940-03-15
Abstract: 581,162. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. March 15, 1940, No. 4868. [Class 40 (v)] The distance between a reflecting object and a radio transmitting station is determined by cyclically varying the rate of change of frequency of the transmitted waves and receiving at a receiver located near the transmitter waves directly from the transmitter and after reflection from the object so as to produce a beat frequency of predetermined value. The rate of change of frequency giving this beat frequency is a measure of the distance of the object. A wide range of distances of reflecting objects produce in turn the same beat frequency. An ultra-high-frequency transmitter is employed, the frequency modulating condenser being cut to give a continuously varying rate of change of frequency. Alternatively, frequency modulation may be effected by employing the "Miller" effect. The cyclic variation of the transmitter frequency is about 10 cycles per second or less, to permit the use of a highly selective receiver. A suitable receiver is shown in Fig. 1 in which the receiving aerial AE is tuned to the ultra-short waves by a circuit TC1 which feeds into a diode detector D. The output of this diode comprises a tuned circuit TC2 which operates at the desired beat frequency, e.g. 1000 cycles per second, and a resistance R shunted by a condenser C so as to produce the correct operating bias for the diode. A circuit TC3 which gives further filtering at 1000 cycles, is coupled to the circuit TC2 and its output is fed to amplifiers V1, V2. The output from the amplifier V2 is passed through a further tuned circuit TC4 which feeds the beat frequency to the vertical deflecting plates of a cathode-ray oscillograph. The time-base deflection is produced by a deflecting wave integrally related in period to the cycle of variation of rate of frequency change.
