Title: Female connector
IPC: H01R12/59
Filed: 1972-12-14
Abstract: 1396519 Two-part couplings ITT INDUSTRIES Inc 14 Dec 1972 [23 Dec 1971] 57691/72 Heading H2E The insulating body of a female connector 1 for a flat flexible cable 19 comprises a receiving member 4 having an entrance 16 for a mating part 17, and a retention member 5 attached to the receiving member by a tape hinge 6. With the bared conductor ends 18 of the cable 19 inserted into the chamber 14, the retention member 5 is pressed against the receiving member 4 until the resilient hooks 9 latch behind bridge pieces 12, clamping the cable 19 between the face 23 and the overhanging part 27 of the receiving member. The bared conductors 18, thus bent down and retained in the chamber 14, constitute the connector contacts engageable with contact surfaces of the mating part 17. A hole (not shown) in the mating part resiliently engages a boss 28 in the chamber 14 to prevent accidental withdrawal. This connector provides a cable entry perpendicular to the direction of insertion of the mating part 17. Modifications (Figs. 2 to 9, not shown) provide cable entries perpendicular, parallel and opposite to that of the mating part.

Title: Photographic Camera with Exposure Meter
Inventor: HAHN ERICH
IPC: G03B7/04
Filed: 1967-12-20
Abstract: 1,179,619. Photographic cameras. PENTACON DRESDEN KAMERA-UND KINOWERKE, VEB. Dec. 20, 1967, No. 57788/67. Heading G2A. In a photographic camera having an exposure meter of the balancing bridge type and including a photoresistance cell R p  H  illuminated through the camera objective, a choice of exposure measurement with "open diaphragm" or with "working diaphragm" may be made. As shown, the photoresistance R ph , Fig. 1, is provided in one branch of a bridge circuit, a variable resistance R 2  and a correction resistance R 1  in another branch, and a meter 5 in the diagonal of the bridge. A sliding contact 4 of a potentiometer R3/4 electrically connected to the meter 5, is rigidly connected to a film speed scale 6 coupled by lugs 8 with a balance setter 7 carrying a shutter scale. If a brightness measurement is required with diaphragm open, a mark selector 9, Fig. 2, is positioned, such that the value of the maximum aperture for the lens in use is opposite a fixed mark B i.e. 2À8 as shown. A spring 13, opens a switch 3, such that a resistance R 1  which compensates for the percentage difference between the rated aperture and its effective aperture is introduced into the bridge circuit. The values of diaphragm and exposure time are then read off selector 9 and setter 7 respectively. If a measuring operation is to be carried out with the diaphragm set to a preselected value i.e. with a "working diaphragm", the selector 9, Fig. 1, is moved so that mark C is opposite the mark B, thereby causing switch 3 to close to short circuit the resistance R 1 . The film speed, e.g., 21 is set opposite mark A and a selected exposure time 1/60 second is positioned opposite mark C by adjustment of the setter 7. The bridge circuit is then balanced by adjustment of the diaphragm of the objective lens, not shown, such that the light reaching photoresistance R PH  is varied.

Title: Methods of etching semiconductor bodies
IPC: C25F3/12
Filed: 1970-12-10
Abstract: 1318770 Semi-conductor devices WESTERN ELECTRIC CO Inc 10 Dec 1970 [16 Dec 1969] 58591/70 Heading H1K [Also in Division B6] In a method of etching semi-conductors, e.g. silicon, germanium or semi-conductors comprising elements of Groups III and V or II and VI, the semi-conductor is immersed in an etchant of a type that etches at an appreciable rate unless a potential at least as great as a passivating potential is applied to the semi-conductor with respect to an immersed counterelectrode, e.g. of platinum, gold or semi-conductor material, this potential being applied to portions not required to be etched whilst the other portions are maintained at a lower potential. In a P-N type semi-conductor, said potential applied to either layer will cause the other layer to be etched away as far as the junction. The passivate layer may additionally be masked by a metallized conductive or dielectric carrier. In a P-N<SP>+</SP>-N type semi-conductor, an etch resistant coating may be applied to the N wafer and said potential applied to either the N or N<SP>+</SP> wafer to cause the P wafer to be etched as far as its junction. For etching a slot in a P-N type semi-conductor a mask is applied to both surfaces, a slot being left in one mask and by making the surface to be etched parallel to a certain crystallographic plane, e.g. the (100) plane, of the semi-conductor, preferential etching forms a slot of a required shape. An outer wafer of a semi-conductor device in a form for producing an air or dielectric isolated semiconductor integrated circuit may be etched away by coating the other outer layer with a conductive coating which acts as a mask and applying to this the passivating potential whilst immersed in the etchant. The passivating potential may be about 0À65 volts, the etchant being an alkali metal hydroxide, ammonium hydroxide, alkyl substituted ammonium hydroxides or aqueous mixtures of hydrofluoric and nitric acid, the etchant being heated to 70 C. or up to their boiling point. Since hydrogen is evolved during etching, when a junction is reached and etching stops a hydrogen detector may be used to actuate a means for removing the semi-conductor from the etchant.

Title: Diffeentail-phase-modulated communication systems
IPC: H04L27/20
Filed: 1973-12-31
Abstract: 1452140 Data transmission; error correction FUJITSU Ltd 31 Dec 1973 [29 Dec 1972] 60192/73 Heading H4P A differential p.s.k. modulated system in which burst like type errors may be corrected by a random error, e.g. single error correcting code of low correcting function comprises dual (e.g. convolutional) coders and decoders supplied with alternate bits so that burst errors are divided into random i.e. single bit errors in 2 bit symbols and random errors per se are corrected by parity bit addition. A distributer 2 comprises a flip-flop combination by which input signals are channelled alternately to inputs P, Q of flip-flop circuits 2a, 2b, hence are converted into three bit parallel signals which are passed (see Fig. 7, not shown) directly to registers 4a, 4b each, together with a parity bit generated in 3a, 3b. Alternate outputs of 4a, 4b are led to shift registers 4c, 4d and thence to differential coder 5 which thus receives alternately pairs of bits from registers 4a, 4b. Differential coder 5 (see Fig. 8, not shown) has three sections, the first converting Grey code into natural binary, and full adders (5b, 5c) providing a differential logic of the natural code to a further natural/Grey code converter (5d) having an exclusive OR (50) in one output. This arrangement is stated to simplify circuitry but other more complex arrangements may be used. The 2 bit output from coder 5, four phase differentially modulates a carrier for transmission. The receive circuitry 10 (not shown) is basically a mirror image of the transmitter with the addition of clock phase adjusting circuit (11a) described in detail with respect to Fig. 12 (not shown). Each data line has three one bit flipflop delay circuits selectable in pairs, i.e. either no delay in both lines or 1, 2, 3 bit delay, by AND gates according to the decoded output of a 4 bit counter (11a 1 ) controlled by a rotate signal from (lid) which decides whether inputs to (12a, 12b) are correctly divided and if not, stepping pulses are applied to counter (11a 1 ). The decision is made by a threshold device (11d 3 ) periodically monitoring an error counter (11d 1 ) and an excess count is considered as an incorrect clock phase hence (11a 1 ) is pulsed. Convolutional decoders (12a, 12b) also include a parity generator are operating on three of the information bits, output from which is compared in an exclusive OR (12 7 ) and 0 for correct or 1 for incorrect is fed to a syndrome register (12 2 ) from which a majority decision circuit (12 3 ) decides whether correction should be made and if so a pulse is applied to exclusive ORs 12 3 , 12 9 , 12 10  (and to sync. circuit (lld)). A 2<SP>m</SP> phase modulated system is envisaged in the Specification with respect to Fig. 16 (not shown).

Patent GB-2014002-A (GB)
Title: Electrical overload protection means
IPC: B60Q11/00
Filed: 1979-02-05
Abstract: An electrical component, such as a resistor R6, is protected against overload by employing a reverse-biased rectifier element Gr2 in contact with or very close to the component to be thermally influenced by that component, so that heating of the component due to an excessive current flow correspondingly heats the rectifier element to allow an increased reverse current flow through it. This rise in reverse current causes temporary or continuous switch-off of the circuit which incorporates the component. In the multivibrator-controlled lamp flasher circuit shown, the rise in reverse current may simply decrease the mark : space ratio. <IMAGE>

Title: Control for an electrical generating and distribution system, and method of operation
IPC: H02J9/08
Filed: 1980-04-15
Abstract: A control for an aircraft electrical generating and distribution system utilizes a plurality of interconnected microprocessors and comprises two engine-driven generators 15, 16 and an auxiliary power unit generator 26 with loads 20, 21 connected to the generators through circuit breakers 18, 19. A distribution bus 22 connected through tie breakers 23, 24, 27 interconnects the loads 20, 21 end the auxiliary generator 26 so that any one generator can power either or both loads. Each generator has a microprocessor control unit 30, 31, 32 responsive to the associated generator conditions to control generator operation. A microprocessor bus power control unit 42 is responsive to distribution circuit conditions and correlates information from the control units 30, 31, 32, to control the tie breakers and distribution of power from the generators to the loads. Serial data links between the control unit 42 and each control unit 30, 31, 32 provides for communication of input and control information and enables comparison of redundant circuit information enhancing reliability of the system operation. A generator voltage regulator uses the generator microprocessor control unit to develop an error voltage which is added to the average generator phase voltage, controlling the current. If phase failure occurs the control unit senses an abnormally high phase voltage, disables the average phase voltage circuit and the regulator continues to operate with the error voltage. <IMAGE>
