Title: Tubular body and process of making it
IPC: A61F2/06
Filed: 1963-12-13
Abstract: Artificial implants (e.g. artery or vein) for a human body or animal comprises a crimped tube made of collagen or of collagen and a non absorbable fibre.  The tube may be straight or Y-shaped. The non absorbable fibre may be a copolymer of vinyl chloride and acrylonitrile, polyvinyl chloride, nylon, polyacrylonitrile, polyethylene terephthalate, polytetrafluoroethylene, polyethylene, polypropylene, cotton or silk.  The tubes may be woven, knitted, braided or crocheted.  The tube may be crimped by inserting a mandrel in the tube and forcing the ends of the tube together or a wire may be wound round the tube in the mandrel before forcing the ends together.  The tube may be set in its crimped state by (1) heating with steam under a pressure of 0 to 18 p.s.i.g.; (2) heating in water at 40 DEG  - 100 DEG C; (3) tanning; (4) heating a crimped tube having a water content of at least 10% by weight at 140 DEG  to 160 DEG C; or (5) subjecting to radiation and u.v. light.  The tanning agent may be chromium, formaldehyde or polyhydroxyphenols.ALSO:Artificial implants (e.g. artery or vein) for a human body or animal comprises a crimped tube made of collagen or of collagen and a non-absorbable fibre.

Title: Vertical resistivity logging
Inventor: RUNGE RICHARD JOHN
IPC: G01V3/26
Filed: 1969-10-09
Abstract: 1279105 Well-logging CHEVRON RESEARCH CO 9 Oct 1969 49717/69 Heading G1N The vertical resistivity of earth formation surrounding a vertical borehole is determined by establishing a substantially uniform, timevarying electromagnetic field over an elongated depth interval in the earth formation to induce a uniform, vertical electric field about the centre of said depth interval, and detecting the potential difference between a pair of electrodes 20, 22 spaced apart about the centre of said depth interval. The electromagnetic field is created by a dipole antenna (10) which is energized by an oscillator (36) carried in the sand 18, Fig. 2 (not shown). The induced electric field is made very much larger than the potential field, due to current flowing in the formation via the ends 48, 54 of the antenna, by adjusting the frequency of the oscillator and the length of the antenna. Alternatively, the potential field may be eliminated by insulating the ends of the antenna, Figs. 2B, 4, 4A, 5 (not shown).

Title: A device for automatically limiting the speed of motor vehicles

Filed: 1964-12-09
Abstract: 1,062,109. Controlling motor vehicles. S. K. SHAH. Dec. 9, 1964, No. 50146/64. Heading B7H. A device for automatically limiting the speed of a motor vehicle comprises multiple contact switch assemblies X, Y which are actuated respectively by a member connected to the accelerator, accelerator linkage or means dependent on the speed of the vehicle and by a member associated with the gear-box of the vehicle, and interconnected by a circuit arranged such that following actuation of the switch Y by selecting the highest gear or another ratio in which the device is desired to operate, the switch X is actuated in dependence on increasing speed or accelerator depression to energize a red warning light at a first predetermined speed or accelerator position, to sound the horn of the vehicle at a greater speed or accelerator depression, and finally to break the engine ignition circuit at a still greater speed or accelerator depression. In the case of a compression ignition engine the switch X finally cuts-off the engine fuel supply. When any gear ratio other than those in which the device is operable is engaged the switch Y renders actuation of the switch X ineffective. As shown, the switch X is actuated by setting screws H, I carried by a sliding rod G connected to the accelerator linkage L, and the switch Y is actuated by a lever K operated when the highest gear is selected. The switch X may alternatively be actuated from the gear-box through the speedometer cable.

Title: System for detecting a digital phase-modulated wave
IPC: H04L27/227
Filed: 1973-10-30
Abstract: 1449866 Digital transmission; phase modulation; phase detectors KOKUSAI DENSHIN DENWA KK 30 Oct 1973 [30 Oct 1972] 50403/73 Headings H4P and H3A The phase shift in a digital phase modulated wave is determined by measuring the time interval between one of the zero crossing points of the wave and a zero crossing of a reference carrier immediately succeeding. The measurement is recorded by counting clock pulses, representative of the interval, the frequency of the pulses being higher than that of the carrier, preferably 2<SP>n</SP> times. The phase of the reference carrier is controlled by lower significant bits of the measured: value. The received wave after passing through a filter. (4) which alternates other frequencies has its frequency raised at (12) and sample timing pulses at each signal element centre are developed at (7). A phase difference detector 9 detects the relative phase of a reference carrier 112 and frequency increased signals 110 which are shaped into square waves by Schmitt trigger circuit 91, and excursions to positive polarity at zero crossings are detected by differentiator 92a which primes AND 94 allowing setting of flip flop 93 to set flip flop 95. The reference carrier is differentiated at 92b which resets flip flop 95; this provides a 1 during the period between zero crossings of waves 110, 112. Clock pulses 121 are fed to a counter during this period through AND 97. If oscillator 96 has 2<SP>n</SP> times carrier frequency, e.g. 32 times then each interval = 2# /32 radians. Output of counter in the case of 8 phase modulation is divided into 2 lower digits 113 controlling deviations, i.e. phase relatively of input 112 from optimum, and 3 upper digits 114 providing digital information.. The arrangement may be applied to either reference phase or relative phase modulation.

Abstract: 1531468 Testing IC engine ignition circuits UNITED TECHNOLOGIES CORP 18 Dec 1975 [19 Dec 1974(2)] 51956/75 Heading G1U An ignition circuit testing system exploits the fact that if the ignition circuit is in good condition then with the secondary winding open circuited for each cylinder firing pulse the voltage, (a), Fig. 3, across the contact breaker should rise above a certain minimum (about 250V) and should execute a certain number of oscillations. To this end, a potential divider 64, ..., 68, Fig. 1, is connected to the contact breaker so that the voltage across it can be compared with a pre-set threshold 74, and its oscillations can be squared 34 (see also (b), Fig.3) and counted. In the preferred embodiment the contact breaker voltage is examined successively over sixteen firing cycles in relation to a particular cylinder, the plug lead 28 for this cylinder being removed and being connected to a signal conditioning circuit 30 to provide appropriate gating signals. The number of firing cycles in which the contact breaker voltage exceeds the pre-set threshold 74 are counted 58, and the total number of oscillations of the voltage are counted 56, 57, so that the most significant four bits 57 represent the average number of oscillations per firing cycle. The resulting counts are then applied to a logic circuit which produces an indication of the likely condition of the ignition circuit. For example, if the number of firing cycles during which the contact breaker voltage exceeds the threshold lies in the 25% to 75% range, lead 90, and if also the average number of oscillations lies in the 4 to 10 range, lead 108, then an indication "intermittent arcing", lead 118, is produced.
