Title: Improvements in Data Transmission Systems
Inventor: MUMFORD HOWARD
IPC: H04L7/04
Filed: 1966-11-02
Abstract: 1,173,140. Detecting specific digital signals. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 31 Oct., 1967 [2 Nov., 1966], No. 49206/66. Heading G4H. A circuit for detecting the occurrence of a predetermined signal pattern in a sequence of binary digits comprises a store to temporarily store each digit of the sequence, a plurality of comparison means each arranged to compare each digit of the sequence with a previous digit stored in the store, and a plurality of switching devices operable by the comparison means to produce a predetermined output when the signal pattern has occurred. In the form of Fig. 1, the incoming signals are applied to a three-stage shift register SR the outputs of which are gated with incoming signals at G1, G2, G3. Gate G1 responds to a "1, 1" combination to pick relay A, gate G2 responds to a "1, -, 1" combination to pick relay B and gate G3 responds to a " 1, -, -, 1 " combination to pick relay C. Contacts of the relays are interconnected to give outputs when specified patterns of digits are present. In another form, Fig. 3, the incoming signals are applied to a bi-stable device T and an inverter I. The output of the inverter is gated at G4 and G5 with the " 0 " and " 1 " outputs of the bi-stable. The signal itself is gated at G6 with the " 1 " output of the bi-stable. Relay A responds to a " 0, 0 " combination, relay B to " 0, 1 " and relay C to " 1, 1." Contacts of the relays are interconnected as before to indicate the presence of larger specified groups of digits.

Feeding sheets; registering; feed tables; faulty feed.-A sheet to be cut is laid on table 20 and registered against side guide 22 and front stops 83, Fig. 3. Table 30 is reciprocated from beneath the table 20 to grip the leading edge of the sheet by means of suction apertures (34, Fig. 14, not shown) in the leading edge of the table 30. Stops 83 are moved out of the path of the sheet on a pivotable shaft 81. Suction apertures (23, Fig. 14) adjacent guide 22 sense for correct registration of a sheet against the guide. Incorrect registration causes tripping of the cutting device. Table 20 is laterally adjustable. Delivering sheets; cutting apparatus.-A sheet carried on table 30 is longitudinally slit and/or scored by laterally adjustable knives 99 carried on bar 93. The slit and/or scored portions are gripped by suction pads 127 when table 30 reaches the end of its stroke. Pads 127 are carried on vertically reciprocating carriage 120. As table 30 returns to its initial position beneath table 20 the gripped portions are retained by the pads and lowered on to stacking table 170. The stacking table is lowered as the pile accumulates in response to the detection of the level of the pile by assembly 120. Suction pads 127 are laterally adjustable in accordance with the position of knives 99. Laterally adjustable strips 185, Fig. 1, serve to align the stack.

Abstract: 1,102,966. Tuning arrangements GENERAL ELECTRIC CO. Ltd. 29 Nov., 1966 [29 Nov., 1965], No. 50642/65. Headings H3Q and H4L. A resonant circuit is tuned to one of a number of pre-set frequencies by connecting a tapped inductance L1-L4 and a tapped capacitance C1-C4 to a number of parallel conductors 3 on one side of an insulating board 7, on the other side of which are conductors 2 at right angles to the first set. A bridging piece 11 slides in a slot 4 in the board and connects the two halves of a particular conductor 2, and at the same time connects permanently the two conductors 3 that are adjacent the slot, thus providing a connection 14 for the other end of the resonant circuit. An electrical connection 10 is made through the board at selected points where the two sets of conductors cross so that by moving the piece 11 any predetermined combination of L and C may be brought into circuit. The conductors may be in the form of a printed circuit. The piece 11 is driven by a string drive from a rotary click-stop mechanism 15. The arrangement can be used for tuning the master oscillator of a transmitter or the local oscillator of a receiver, in conjunction with crystals selectively switched in, e.g. by a similar arrangement geared to the first. Several tuned circuits can also be ganged together in the same way. The shortest conductive paths are preferably associated with the highest resonant frequencies.

Patent GB-1077320-A (GB)
Title: Improvements in and relating to semiconductors
IPC: H01L21/203
Filed: 1965-12-03
Abstract: A semi-conductor device containing an abrupt PN junction is produced by sputtering silicon of one conductivity type on to silicon of the opposite conductivity type.  The process takes place in an inert atmosphere and is stated to result in an epitaxial deposit.  Fig. 1 (not shown) depicts the sputtering chamber (10) in which a silicon substrate (20) is placed between an anode (16) and a cathode (13), the latter consisting of the silicon to be deposited. In the chamber atmosphere - which consists of an inert gas such as Argon containing not more than 0.002% oxygen - a glow discharge is set up and the positive gas ions thus produced bombard the silicon cathode to release silicon particles which are sputtered on to the substrate.  A nickel mask may be placed between the cathode and the substrate during the deposition. A similar mask may be used in the subsequent provision of evaporated-on aluminium electrodes.
