Title: Composite steel and prestressed concrete pile - is steel tube contg. axially stressed concrete tube
IPC: E02D5/58
Filed: 1974-01-03
Abstract: The stressing wires (3r are dispersed uniformly in the concrete section, the concrete being in intimate contact with the steel sleeve and one end of the concrete tube projecting freely beyond the steel sleeve. Annular end plates (4, 5) are used to terminally anchor the stressing wires; the plate (4) at the fixed end being welded to the outer steel tube.

Patent FR-2284017-A1 (FR)
Title: Plug insert for neutralizing alarm system - has specific resistance and forms key for socket forming lock
IPC: G07C9/00
Filed: 1974-09-04
Abstract: The system is significantly more economic than prior art is extremely sensitive and does not require forceful insertion likely to sound the alarm. The voltage is produced from an arrangement comprising a voltage U1 relating to key resistance and two fixed voltages U2 and U3 and is obtained when the condition U2U1U3 is satisfied. The insertion of a random resistance in the socket provokes a current in resistor (R1), which, with the key, forms the dividing bridge. The bridge produces a voltage actuating the alarm using the unlocking of a transistor. The emitter and the base of the transistor are connected to the terminals of the resistor (R1).

Title: Low-carbon chrome steel and chrome-iron alloys - obtd by decarbonisation of high carbon chrome-iron
IPC: C21C7/00
Filed: 1975-01-24
Abstract: Low-carbon chrome steel or chrome-iron alloys are made from a chromium-iron mixture rich in carbon, with minimal transfer of Cr to the slag layer, by passing O2 and a finely divided carbonaceous material, e.g. powdered coal, in a carrier gas, e.g. CO2, through adjacent feeder pipes into the molten metal. As the C content of the melt is lowered from 0.2 to 0.05% the gas flows are adjusted so that the molar ratio O2:C gradually changes from an initial 1:0.1 to a final 1:0.9. Gas feed is 3-100 l per kg of carbonaceous material. High quality low carbon Fe/Cr alloys can be made from the product of reducing chromite with C instead of the more expensive alumino-thermic reduction.

Title: Capacitor with fusible link - uses pure iron link in internal refractory sleeve
Inventor: BOZZINI CHARLES
IPC: H01G4/40
Filed: 1976-02-19
Abstract: This capacitor has a fusible link of pure-iron incorporated into its construction. The link (5) is connected in series between the foils of the capacitor and an external conductor. It is located within the foils and is protected by a refractory sleeve (6). The solder connections at either end of the sleeve prevent an ingress of resin into the sleeve. The use of pure-iron rather than silver enables a mechanically stronger link to be used for small capacitors.

Title: Error detection circuit for numeric transmission systems - operates using polarity control and is applicable to PCM systems using shift registers
Inventor: JESSOP ANTHONY
IPC: H04L1/24
Filed: 1976-10-08
Abstract: An error detection system is for pulse code modulation transmission of numerical data, the design providing such detection without the need for increased data transmission speed. Detection is based on operations controlling parity which is achieved by replacing in a system emitter, an allowable combination of some number of successive numeric elements by a unique combination of the same number of successive elements and providing an output which is a function of parity control. The circuitry employs two shift registers which store the bit sequences for parity comparison and provide an error signal as required. A blocking circuit connected to the first register and to co-incidence circuits preventing transmission of detected error bits.

Title: Railway vehicle detector in track section - uses Q factor measurement principle with conductor loops between non metallic rails
IPC: G08G1/042
Filed: 1976-12-30
Abstract: A method is used for detecting a vehicle occupying a railway track section. It involves the alteration of the Q factor of a loop laid along that section when a vehicle is in it. The method operates for all vehicles with substantial metallic content, and is not made ineffective by non metallic vehicle wheels or rails. Conducting loops (15,16,17) are laid on the railway track between the rails (10,11), one loop in each sector, and each loop is served by a drive and detection circuit (20,21,22). The drive circuit consists typically of a Hartley type transistor oscillator (25) with the sector loop (16) connected as a load via a capacitance (44). When a vehicle is present, the reduction in the loop Q factor stops the oscillator oscillating. A rectifier (48) and detector (50) attached to the oscillator output monitor this and display the presence of a vehicle in that sector.
