Title: Improvements in and relating to tubular outer conductors or screens for concentric high frequency cables
IPC: H01B13/22
Filed: 1937-12-18
Abstract: 507,613. Cables. FELTEN & GUILLEAUME CARLSWERK AKT.-GES. Dec. 18, 1937, Nos. 35131 and 35132. Convention dates, March 22, 1937 and May 27, 1937. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 25, 1938.] [Class 36] [Also in Group XXII] A tubular outer conductor or screen for a high-frequency cable comprises two or more arcuate metal bands, such as 61, 65, Fig. 1, assembled together with abutting edges and provided with transverse grooves 63, the grooves of one or more of the bands terminating in projections 64 which engage the inner surfaces of the edge portions of an adjacent band or bands and prevent lateral displacement of the assembled bands. Each band may be provided with the projections so that adjacent bands can be displaced longitudinally relatively to one another only by a distance equal to that between adjacent grooves in one band. Alternatively, and as shown, the grooves of one band of an adjacent pair may be formed with cut-away end portions 66 past which the projections of the other band may slide, so that relative longitudinal displacement of the two bands is unlimited. Fig. 3 shows a machine for providing the transverse grooves 84 and projections 85 in a pair of arcuate bands which are advanced side by side between press members 86, 87 of a press 81 by conveying wheels 90, 91, the advancement being intermittent and through steps corresponding to the distance between two adjacent grooves. The press members close upon the bands whilst they are stationary and plungers 82, 83 are then depressed to form in each band a groove and its associated projections. The upper press member and the plungers are then lifted and a cam 89 causes a lever mechanism to raise the bands from the lower press member, after which the bands are advanced by the conveying wheels. The cycle then re-commences with the press members closing. Instead of intermittent feed, continuous feed of the bands may be employed, in which case the press is so arranged as to move along with the bands whilst it is pressing a pair of grooves and then quickly return to its initial position to commence another pressing. Alternatively, a plurality of upper and lower press members may be arranged respectively on a co-operating pair of conveying bands or large wheels. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 507,909, [Group XXII], and describes also constructions wherein the metal bands are folded together at their edges, the folds being cut out at the grooved portions of the bands, and, preferably, slits being formed in the grooves. This subject-matter does not appear in the Specification as accepted.

Title: Method for the recovery of desmosterol -c27h44o- and derivatives thereof from vegetable products
IPC: C07J9/00
Filed: 1972-07-31
Abstract: 1355272 25-Hydroxycholesterol; desmosterol CAMEROUN STATE OF 31 July 1972 [3 Aug 1971 3 Feb 1972 (2)] 35717/72 Heading C2U 25-Hydroxycholesterol is prepared from a mixture of desmosterol with other phytosterols, by treating said mixture (e.g. with mercuric acetate and then sodium borohydride) to convert the demosterol into 25-hydroxycholesterol which is then isolated (e.g. by chromatography or fractional crystallization). 25-Hydroxycholesterol may also be obtained by saponification of its 3-acetate (described below). 25-Hydroxycholesterol 3-acetate is prepared by a modification of the above process wherein the initial mixture is first acetylated and, if desired, a fraction rich in desmosterol acetate is obtained by chromatography over alumina impregnated with silver nitrate. The acetylated mixture or fraction is then treated as described above. Desmosterol is prepared by dehydration of 25- hydroxycholesterol (prepared as described above), e.g. using concentrated sulphuric or phosphoric acid or POCl 3 . Desmosterol is also obtained by saponification of its 3-acetate. Desmosterol acetate is prepared by dehydration of 25-hydroxycholesterol 3-acetate (prepared as described above), e.g. using POCl 3 . The above mixture of demosterol with other phytosterols may be prepared from the whole or part of a plant of the family Phanerogamae, e.g. tribe Apocynaceates, e.g. species Funtumia or Holarrhena, the preferred source being seeds of Funtumia Elastica. The plant material is extracted with an organic solvent (e.g. petroleum ether), and the material extracted is saponified and then acidified. The resulting mixture is extracted, e.g. with diethyl ether, petroleum ether or hexane, and the extract dried and evaporated. Chromatography of the residue yields a fraction consisting of the desired desmosterol/phytosterol mixture and also a fraction consisting of a mixture of cycloartenol, 24-dehydrolophenol, 31-norlanosterol and other unspecified phytosterols.

Title: Pressure metering valve for hydraulic brake system
IPC: B60T11/34
Filed: 1966-08-10
Abstract: 1,106,582. Hydraulic brakes; valves. KELSEY-HAYES CO. 10 Aug., 1966 [13 Aug., 1965], No. 35840/66. Headings F2F and F2V. In an hydraulic braking system for a vehicle of the kind comprising a master cylinder which supplies fluid to disc brakes on the vehicle front wheels and, by way of a proportioning valve to drum brakes on the rear wheels of the vehicle, an additional valve 31 is interposed between the master cylinder and the disc brakes to determine a threshold pressure of the master cylinder below which the disc brakes are not energized, the valve 31 being so constructed that it closes rapidly at a first very low pressure, which is insufficient to energize the brakes, opens at a second pressure above that necessary to overcome the resistance of the return springs of the drum brakes, and thereafter successively closes and opens to modulate the output pressure such that it rises faster than master cylinder pressure, until the output pressure equals the master cylinder pressure whereupon the valve remains permanently open. For this purpose, the valve consists of two members 61, 101, the former being held initially against an end face 67 by the resilience of a diaphragm 81 acting upwardly on a plunger 71, and the latter carrying a seat 113 which is pressed by a pre-stressed spring 105 against a shoulder 103 and is also adapted to seal against the member 61. When fluid is supplied to the inlet 45, it is first able to pass around the member 61 by way of radial passageways 69 and peripheral passageways 65, so that pressure builds up in bore 51, which communicates with the brakes via outlets 47, 49, and acts on diaphragm 81, whereby the plunger 71 is moved downwardly when the first very low pressure is reached to allow member 61 to fall and engage the seat 113. The resistance to flow provided by the passageways 69, 65 ensures that the valve member 61 cannot be beaten by rapid increases in master cylinder pressure. When the second, higher, pressure is reached the valve assembly 61, 101 moves to compress the spring 105 and allow fluid to pass via peripheral passageways (117) in the member 101 (Fig. 4, not shown) to the bore 51 so that pressure again builds up at the outlets 47, 49. As pressures on the two sides of the valve assembly tend to become equalized the spring 105 re-closes the valve and further rise in inlet pressure successively opens and shuts the valve to maintain a balance between input and output pressures, the latter rising more quickly than the former owing to the difference between the area of member 61 and that of a thickened portion of plunger 71 received in a bore 73 of a closure member 75, until, when the pressures become equal, further rise in master cylinder pressure opens the valve permanently. Diaphragm 81 provides a seal for the closure member 75 and allows the plunger to pass out of the valve housing for manual operation to facilitate bleeding of the brakes.

Title: Railway track circuits
IPC: B61L1/18
Filed: 1960-10-25
Abstract: 927,372. A.C. track circuits. WESTING- HOUSE AIR BRAKE CO. Oct. 25, 1960 [Oct. 28, 1959], No. 36564/60. Class 105. An A.C. track circuit, which in addition to normal operation also releases its track relay for a limited period when the track rails are subjected to a relatively high resistance shunt, comprises an insulated track section 10 which is connected at one end to an A.C. source 9 and at its other end to a saturable transformer 31 which supplies track relay 55 via the emittercollector path of transistor 43, connected in series with non-saturable transformer 25, which supplies an output for controlling the conduction of the emitter-collector path of transistor 43 via a second transistor 81. The base circuit of transistor 43 is biased from the rectified output of transformer 31 via a voltage dividing network including thermistor 63 and resistor 65, shunted by condenser 59, and the emittercollector path of transistor 81 and the base circuit of transistor 81 are biased from the rectified output of transformer 25 via a voltage divider circuit which includes resistor 77 and resistors 89 and 73, shunted by a large value condenser 71. In normal operation, both transistors conduct and relay 55 is energized. On application of a low-resistance shunt across the rails, the output of transformer 31 reduces to a sufficiently low value to release the relay. On application of a relatively high resistance shunt the whole of the voltage reduction is applied to transformer 25, since saturated transformer 31 tends to maintain a constant input voltage and this decrease produces a reversal in the polarity of the voltage drop across resistor 77 during the discharge time of condenser 71. Transistor 81 cuts-off and the base potential of transistor 43 rises to a positive value, with respect to its emitter, which cut-off the transistor and releases relay 55 in its collector circuit. Relay 55 remains released for a period determined by the discharge time of condensers 71 and 59 and its own inherent time delay.
