Patent DE-1955842-B2 (DE)
Title: Line scan for TV sets using thyristors - uses two thyristors and three diodes as only active components in cct.
IPC: H03K4/62
Filed: 1969-11-06
Abstract: This method requires relatively few active components and requires less current than previous ccts. e.g. perhaps only some 16 W are required for a colour CRT having a 90 deg. scan. A supply of only 140 V to 150 V d.c. may be required. In the first half of the line scan a diode conducts. During the second half of the scan a thyristor conducts. It is switched off at the beginning of the line fly-back by a second thyristor which is triggered by line synchronising pulses. The first diode gives flywheel action across the blocking thyristor. The efficiency of the circuit is improved by a series connected diode and inductor which returns a set amount of energy to a capacitor across the supply.

Title: Hermetically sealed housing for thin or thick film components - uses solder on metallised layer to seal cover to connection tags
IPC: H01L25/16
Filed: 1971-04-29
Abstract: The hermetically sealed housing consists of a hollow cover (4) that sits over the circuit assembly (1) and has holes through which the circuit external connection tags (3) pass. A metal film (6) is deposited on the inside faces of the holes followed by a film of solder (7). The cover is then placed over the circuit and both heated to melt the solder. The solder thereby forms a hermetic seal with the connection tags.

Title: Ice-breaker oil tanker - with ice girdle compartments in double skin hull
IPC: B63B3/16
Filed: 1971-11-06
Abstract: 'Icebreaker-tankers' with a reinforced outer skin in the form of at least one ice girdle compartment, which is provided with a frozen water filling during the voyage through ice-floe contg. waters. While giving a marked increase in strength to the ice breaker-tanker hull so that it can successfully withstand impact with floating ice floes or blocks, the girdle compartments may be emptied in travelling through warmer waters so that no permanent wt. penalty is imposed e.g. as is the case where the filling is reinforced concrete. The ice breaker-tanker has a hull of double skin construction with the usual reinforced bows. The two skins are pref. fabricated from a steel having good ductility at sub zero temps.

Title: Control for flexible shaft hand tool - has speed setting unit and current limiter outside hand tool for improved operation
IPC: H02P7/295
Filed: 1972-01-27
Abstract: The series motor driven hand tool for grinding, milling and drilling uses a flexible shaft (3) for transmitting the torque of the motor (M) suspended from a stand (5). The motor is connected to the control unit (7) which is supplied from the a.c. mains, and the speed of the shaft is controlled by depressing the knee-operated lever (9) or a pedal. The control unit features a transistor, the base of which is fed with a voltage depending on the speed setting, while the emitter is fed with the pulsating voltage derived from a.c. rectification, and fed to a delay line. The control electrode of the thyristor receives its signal through the transistor collector circuit which may include one or more transistors.
Patent DE-2218954-B2 (DE)
Title: Clock with 24-hour dial - has a dial which shows 1 to 12 or 13 to 24 by using oblong slot
IPC: G04B19/16
Filed: 1972-04-19
Abstract: The clock has a mask with twelve openings mounted in front of the dial bearing two rings of numbers. The numbers are arranged so that one ring of numbers 1-12, will show through the twelve openings when the dial is in one position. The second ring of numbers 13-24, is arranged so that 13 is placed above 1, 14 above 2, etc. up to 24 above 12. When the dial is moved vertically downwards behind the mask the numbers 13-24 will show through the twelve openings. The dial is free to slide in the vertical plane guided by two pins which pass through vertical slots in the dial. A lever from the clock movement moves the dial behind the mask.
Patent DE-2226708-B2 (DE)
Title: Phase compensation system for branched aerial connections - uses different lengths for branches giving double compensation for different frequencies
IPC: H03H7/48
Filed: 1972-05-30
Abstract: The phase compensation system for branched aerials for, e.g. t.v. signal transmission, reduces echoes. Where four aerial elements are connected at a junction to a feed line, one pair of the transmission lines connecting them are a quarter wavelength longer than the other pair and they are connected by a transformer with a transmission ratio of 1:4. Where a multiple branch connection is used, the portions of the oscillations from the branch connection points transmitted and then reflected back again are compensated according to their phase position. The two phase compensations for different operating frequencies are applied so that the band width is increased, or for a given band width, the reflection is decreased by applying two phase compensations for only one operating frequency. (DS).
Patent DE-2231614-B2 (DE)
Title: Printed circuit board with conducting paste filling circuit - formed in developed photopolymer layer
IPC: H05K3/12
Filed: 1972-06-28
Abstract: The printed circuit board if mfd. by depositing a photopolymer layer on top of a degreased board (without metal layer). The desired circuit configuration is then projected optically into the polymer layer. The polymer is then developed normally to give the circuit configuration on the board. A conducting viscous dispersion or paste is applied and fills the gaps (the circuit configuration) left by the developing process. The developed photopolymer is left on the finished circuit board. Method is rapid and therefore cheaper.
Patent DE-2326873-B2 (DE)
Title: Error detector for shift registers - detects error by detecting persistence of output state of register
IPC: G11C29/00
Filed: 1973-05-25
Abstract: The error detector, for e.g. a shift register handling binary or multi-level digital signals, monitors the shift register's output and detects an error by determining whether any one of the possible states the register's output may assume has persisted longer than a given time. The input to the register is code converted and then converted back again at the register's output downstream of the detector. The advantage lies in extending the application of digital techniques by making shift registers more reliable.

Abstract: A "fire-safe" packing arrangement (104) for a valve stem (72) which extends through a packing chamber in a valve bonnet bore (42) to a valve chamber (50) in a valve body (12). The packing arrangement (104) comprises a low temperature packing assembly (112)positioned within the packing chamber between the stem (72) and the wall of the bonnet bore (42) for sealing therebetween at normal temperatures and resting on an inner annular shoulder (62) provided in the bonnet bore (42). A metal spacer ring (116) is positioned within the packing chamber axially outward of the low temperature packing assembly (112) with respect to the flow passage (18, 20) through the valve. The spacer ring (116) has a lower side or inner end (140) thereof resting on the low temperature packing assembly (112). The packing arrangement includes a high temperature packing assembly (114) positioned within the packing chamber between the stem (72) and the wall of the bonnet bore ( 42) and axially outward of the spacer ring (116) with respect to the flow passage (18, 20). The high temperature packing assembly (114) is sandwiched between the outer end portion (138) of the spacer ring (116) and a retainer (106) seated on an annular shoulder (58) provided in the bonnet bore (42). The high temperature packing seals between the stem (72) and the valve body (12) at above normal temperature conditions of the valve body (12) which are destructive of the low temperature packing assembly (112). The packing arrangement (104) effectively seals throughout the range of low and above normal temperatures without imposing frictional drag on the valve stem.

Abstract: In the data exchange system operating with processor chip-cards, the chip-card transmits encrypted identification data I, v and, on the basis of a random discrete logarithm r, transmits an exponential value x = 2<r> (mod p) to the subscriber, who in turn transmits a random bit string e to the chip-card. Through multiplication of the stored secret keys s by the bit string e and addition of the random number r, the chip-card calculates a y-value which it transmits to the subscriber, who in turn calculates an x-value from y, v and e and checks whether the calculated x-value matches the transmitted x-value. To provide an electronic signature, a hash value e is first calculated from an x-value and the message m which is to be signed, and subsequently a y-value is calculated from r, sj and e. The numbers x and y then provide the electronic signature for the message m. <IMAGE>
