Title: Improvements in or relating to gunn effect apparatus
IPC: H03B9/12
Filed: 1966-11-02
Abstract: 1,125,115. Gunn effect arrangements. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 2 Nov., 1966 [26 Nov., 1965], No. 49219/66. Heading H3T. [Also in DivisionH1] A Gunn effect apparatus comprises a Gunn effect element having at least one additional intermediate contact along its length dividing the element into a plurality of component lengths, the bias voltages applied to the various lengths being such that the amount of negative resistance exhibited by one length is sufficient to cause it to act as an oscillator while the amount exhibited by another length is only sufficient for it to act as an amplifier. In one embodiment the element consists of two lengths, the oscillator being used to change the frequency of the input or output signals of the amplifier, and a non-linear load resistance may be included in the part of the circuit common to both lengths. Alternatively, the element may include a p-n junction for frequency changing and the oscillator may be arranged in a resonant circuit, a further p-n junction being provided in the element for rectifying or demodulating the output oscillations. In a further embodiment an amplifying length is present between two oscillators. The behaviour of the various lengths may be modified by subjecting them to light irradiation or to variations in temperature, mechanical bias or electrical bias.

Abstract: 1,200,205. Miscellaneous releasable fastenings. W.-D. KLINK. 2 Nov., 1967 [23 Jan., 1967], No. 49922/67. Heading E2A. A motor-vehicle safety-belt buckle mechanism comprises a single housing 1 within which are disposed two independent latching mechanisms to secure the tongues 6 of two safetybelts, the latching mechanisms being separately operable to enable the tongues to be individually secured and released. Each latching mechanism consists of a latch bolt 13, a spring 16 biasing the latch bolt to the latching position and means for moving the latch bolt to the releasing position. The housing 1 is a single casting made of metal or plastics material and its aperture 2 is symmetrical and is divided by a partition 3 so that the cavities for rediving the tongues are mirror images of each other. In each cavity there is a guide rail 4 and insertion slots 5 for the tongues 6 are formed between the partition 3 and the rails 4. The rails 4 project beyond the housing 1 their extensions forming the means 7 by which the housing is secured to the floor or transmission tunnel of the vehicle. The partition 3 is held in grooves in the housing 1 and joined by the means 7 by a screw 9 and a nut. The bolts 13 are mounted in guide bushes 17 and project through holes 11, 12 in the rails 4. The bolts are moved to releasing position by levers 14 which engage inclined surfaces 15 of the housing so that as each lever is moved the respective bolt is both rotated and moved axially. An ejection spring 19 for the tongue is arranged in each slot 5. In a modification instead of the housing being a one piece casting it is made up of two shells which are made of metal or a suitable plastics material and which have a joint extending in the median plane of the partition 3; in a modification of this construction each shell is hollow and provided with internal reinforcing webs.

Hopper feeders of carding machines are maintained charged at a desired level by a device comprising a storage container 9 and delivery mechanism that includes a feed roller 22 suspended to move to-and-fro in association with a rear wall 35. The rear wall 35 is pivoted at 36 and connected by an arm to the shaft of roller 22 which serves to feed fibres into the storage chambers 2 in conjunction with a feed roller 20. In the chamber 2 may be a float member, photocell or other control member for a motor 26 driving the rollers 20, 22 and operative in dependence on the level of fibres in the chamber 2. At complete emptying of the housing 10, the roller 22 closes the passage between the roller 20 and itself. Rocking flaps 16 in the storage container 9 co-operate with electric switches to signal by optical or audible means when maximum or minimum filling levels are reached. The delivery mechanism may be moved away from the storage container should the hopper feeder be moved.

Title: Programme controlled data processing systems

Filed: 1972-11-01
Abstract: 1400631 Data processing system SIEMENS AG 1 Nov 1972 [18 Jan 1972] 50249/72 Heading G4A  A data processing system comprises processing and storage system units, each unit including at least two functionally equivalent (redundant) devices and at least one unit including three functionally equivalent devices, each device having a three port input/output connection, a comparator connected between two of the three ports, and a logic device connected to all three ports. Two embodiments are described. In the first a storage unit is formed of triplicated stores SE1-SE3 and a processing unit is formed of triplicated processors VE1a-VE1c. The individual processors and stores are interconnected via three port input/output terminals. Each terminal has a comparator VS1-VS3, V1a-V1c connected between two ports such that each comparator receives data supplied by a different pair of devices. In the case of a fault in a single device (store or processor) the faulty device may be identified by analysing the comparator signals. Each store and processor receives fault (non-equality) signals from each comparator to which it feeds data and the device (store or processor) receiving a fault signal from two comparators is faulty. Each terminal includes a majority logic circuit MS1-MS3, M1a-M1c formed of three two input and one three input NAND gates.  In the second embodiment three stores are connected to two processors. Since there are only two processors the store terminal comparators are connected to the same processors, one port of each terminal being unused and being held at a logic level such that the majority circuits provide the correct output. The majority circuits in the processors are replaced by logic circuits arranged to enable a single faulty store to be located. A faulty processor cannot be located in this embodiment except by the use of special test programs or parity circuits which are referred to.

In an assembly 201 of modular female connectors 203 as claimed in the parent Specification, each associated with a male connector 204 as disclosed therein, the male connectors are interlocked to form a composite plug 202. The interlocking means may comprise double dovetailed keys (206) (Fig. 2, not shown), co-operating with grooves in the male connector sleeve. The keys have heads (208) engaging gaps (210) in the male connectors 204 and a rearward extension of a key may function as a marker (Figs. 7, 8, not shown). For correct mating at least one pair of contacts in the male and female assemblies may be replaced by locating members (Fig. 3). The rear end 211 of the male connector accommodates male locating member 212 having L-cross-sectioned extension 213 which only interfits with female location member 220 when the two assemblies are correctly aligned. Member 203 is one of the two sleeves characterizing the female connector in the parent Specification. A locking rod passes through a central bore in the location members and is threaded at either end to take locking nuts (Fig. 4, not shown). Each modulator unit of the male and female assemblies may have four contacts, those in the female assembly comprising blade contacts disposed along diagonals and insulated from each other (Figs. 5 and 6, not shown).

Abstract: 1346979 Typewriters TRIUMPH WERKE NURNBERG AG 17 Nov 1972 [16 May 1972] 53325/72 Heading B6F Tabulation.-In a typewriter equipped for variable spacing by the provision of indexing racks (21, Figs. 1 and 2) of differing pitch a and b, the tab stops 15 are set at pitch a. To compensate for the difference in pitch between the tab stops and rack (21) of pitch b, a central stop 14 forming part of a pivoted trigger 12 carries out a rocking motion as a cam follower 17 on the trigger moves over the cam surface of a control rail 22, as shown in Fig. 4. The tabulating mechanism operates as follows:-  When pawl control (5, Fig. 1) is rotated about pin (4), the indexing pawl (2) is disengaged from rack 21. A double arm detent lever (10) latches the pawl control (5) in the rotated position, and the pawl control is shifted up against the left hand end of hole (6) by means of a spring. The type carriage is then free to move until central stop 14 strikes a tab stop 15, so that the pawl control (5) moves and the right hand end of hole (6) engages pivot pin (4). Detent lever (10) therefore releases the pawl control (5) so that under the action of springs (23) and (3), the tooth (8) of indexing pawl (2) drops into rack (21). This completes the tabulating operation (Fig. 3) and the cam follower 17 is no longer in contact with control rail 22.
