Abstract: 1,131,300. Dibenzocycloheptatriene and diene derivatives. RHONE-POULENC S.A. 6 Oct., 1967 [24 Oct., 1966], No. 45883/67. Heading C2C. Novel dibenzocycloheptatriene and dibenzocycloheptadiene derivatives of the general formula wherein R represents a hydrogen atom or a methyl group and the symbols R<SP>1</SP> each represent a hydrogen atom or together form a single bond and pharmaceutically acceptable salts thereof are prepared by subjecting a compound of the formula wherein R<SP>1</SP> is as defined above, to the Willgeradt reaction or the Kindler modification of it and hydrolysing by methods known per se the amide or thioamide thus formed to the corresponding acid. When R must represent a methyl group, a compound of Formula II wherein R=H is subjected to a Darzen reaction followed by oxidation of the product aldehyde of the formula An alternate process comprises hydrolysing and simultaneously decarboxylating a dibenzo-[a,d]cycloheptatriene derivative of the general formula wherein R<SP>11</SP> and R<SP>111</SP> each represent an alkyl group containing 1-4 carbon atoms by the methods known per se for hydrolysing and decarboxylating malonic esters.

Title: Improvements in or relating to dish washing machines
IPC: E03C1/184
Filed: 1963-11-20
Abstract: 1,047,948. Dish-washing machines. SIEMENS-ELECTROGERATE A.G. Nov. 20, 1963 [Nov. 30, 1962; Jan. 5, 1963], No. 45887/63. Heading A4F.

Title: Microwave phase shifters
Inventor: DIPIAZZA GERALD CHARLES
IPC: H01P1/185
Filed: 1969-09-18
Abstract: 1287108 Phase shifters WESTERN ELECTRIC CO Inc 18 Sept 1969 [20 Dec 1968] 46021/69 Heading H1W A microwave phase-shifting network comprises three branches of # or tee configuration each containing reactances and a diode the bias on which determines the reactance of the respective branch. Fig. 1 shows a # network composed of conductors 3, 4, 5, 6, 7 enclosed between a pair of ground planes. The series branch comprises an inductance 8 and diode D3. The shunt branches comprise diodes D1, D2 and quarter-wave impedance inverting sections 6, 7. Bias connections to the diodes are made through feedthrough capacitors C4, C5, C6 and chokes 9, 11, 12, the different bias circuits being isolated from each other by capacitances Cl, C2, C3. The diode D3 is connected to an earth connection 24 via choke 10. When all the diodes are back biased they become capacitative, but, because of the inversion properties of lines 6, 7, the shunt networks become inductive. The network therefore effectively provides a high-pass #- section filter network. This may be changed to a low-pass section by reversing the bias (and hence the sign of the reactances). The consequent change of phase-shift is from negative to positive and is constant over a substantial frequency range. In the modification of Fig. 6, the series branch comprises a diode D3 in parallel with a capacitance C13 and in series with an inductance L3, these being realized by printed-circuit techniques made clear by the drawing. The shunt networks comprise diodes D1, D2 respectively in parallel with inductances L1, L2 and in series with capacitances C12, C14, there being no impedance inverting sections. Bias is applied to terminals 71, 72, 73, the bias circuits comprising chokes 68, 69, isolating capacitances C7, C8 and feed-through capacitances C9, C10, C11. These capacitances are formed by depositing electrodes which overlap the conductors on either side of an isolating gap. The branch reactances are chosen so that if the three diodes are back biased, the series branch becomes capacitative and the shunt branches inductive, reversal of bias resulting in reversal of the branch reactances. The circuit functions in the same overall manner as that of Fig. 1. An n bit phase-shifter (Fig. 9, not shown) may consist of a tandem arrangement comprising a 180 degree phaseshifter, a 90 degree phase shifter and so on until subdivision results in the nth bit.

Title: Hydraulic connector
IPC: F16L37/23
Filed: 1975-11-06
Abstract: 1531274 Female connectors BRITISH PETROLEUM CO Ltd 6 Nov 1975 46041/75 Heading F2G A female hydraulic connector unit 22 is used with a male connector unit 19 at an underwater location. The female connector has a hollow body 1 with a first opening 24, a second opening 23, a third opening, ports 5, and a fourth opening, ports 10. A reservoir 12 is formed by a skirt 7 that has ports 6. These ports are kept closed by locking ring 16 when it is in a locking position. It is so biased by spring 14 so that it engages balls 30 and forces them radially inwardly. A sleeve 8 is movable to shut one of the sets of ports 5 and 10. Member 31 and male connector 19 have valves 3 and 28 respectively biased to a closed position. In use the female connector is held with opening 24 facing downwardly. The interior thereof is filled with a hydrocarbon oil down to the level of parts 10. To make a connection locking ring 16 is manually moved upwardly so that ports 6, 18 are aligned. The male connector is inserted which causes sleeve 8 to move upwardly and shut off ports 5. The oil is forced from interior space 20 through ports 10 into the reservoir. Water in the reservoir is forced out through ports 6. As member 31 and male connector 19 approach each other the pressure is sufficient to open valves 3 and 28. When the connectors are fully mated the locking ring is moved downwardly so that the male connector is firmly gripped. Disconnection follows a reverse procedure except that ports 10 are closed and ports 5 are open. To use the female connector upside down, a liquid immiscible with, and denser than water is used in place of the hydrocarbon oil.

As shown in Fig. 3 the backrest is adjusted by means of strip spring 4 being clamped in the nip between cam 7 and anvil 10. A bent end 8a of the shaft 8 carrying cam 7 is biased by spring 9 to the clamping position. A spring 5 urges strip 4 leftwards to bias the seat back forwardly when the clamp 7, 10 is released. The operating lever (14), Figs. 1, 2 (not shown) has a hollow end 14a Fig. 4 which fits over shaft 8 and is engaged for limited relative rotation therewith by screw 18 engaging slot 19. (Alternatively a screw in end 14a can engage a slot - shaft 8). The valve releasing member 15 is clamped to the end 14a by a pinch bolt. Anticlockwise rotation of end 14a releases cam 7. Clockwise rotation depresses valve stem 16 without rotating shaft 8.

Abstract: 1414220 Rollers; toothed gearing LINDAUER DORNIER GmbH 4 Oct 1973 [28 Oct 1972] 46457/73 Headings F2U and F2Q In a device for imparting an oscillatory lateral motion to the lengthwise travel of a web, a roller 2 rotates upon a spindle 1 which is non- rotatable about its own axis, and rotation of the roller produces a precessional motion of one end of the roller. This latter motion is derived from planetary gearing, comprising an internal ring gear 12 of differing number of teeth but of the same pitch circle, together with a meshing pinion 14 carried by roller 2. Ring gear 12 forms part of a rotatable assembly in which a slot 11 accommodates a bearing stub shaft 6, clamped by nuts 10 at any desired setting of eccentric throw. Gear members 12, 13 and 14 may be exchanged to obtain different precession frequencies. The roller may be rotated by the web of material, e.g. textile, paper or film, or alternatively it may be separately driven.

The transistor 7 acts similarly to a strain gauge. A ceramic beam (Fig. 4) of alumina, of initial thickness b, has a thinned part 11, thickness c, formed by machining. A tranverse slot 13 is formed by a diamond wheel or ultrasonic machining. The surfaces adjacent the slot 13 are smoothed and coated with gold film 16, 17  (Fig. 5). Film 17 has an extended portion 18. Two side coatings 19, 20 are also provided. Coatings 19, 20 are connected by leads (31), Fig. 6 (not shown), to the transistor 7 and extend to a damping block 5 for connection to circuitry (not described). The transistor 7 is soldered across the slot 13 (Fig. 7) by a gold-silicon solder. The beam is assembled in a housing 6 in a manner similar to that shown in Fig. 1. The side of the slot 13 is then cut using a laser beam, thereby separating the two parts 10, 11. The laser beam also cuts through the housing 6. In another embodiment (Fig. 9, not shown) one side of the beam 3 is adhered to a glass base (26) and the other side is abraded to provide a thinned part 11 and the slot 13. The beam is then unstuck and assembled in a housing 6. The laser cut is then carried out at the base of the slot 13.
