Title: Tubular waveguides
IPC: H03K9/10
Filed: 1957-05-17
Abstract: 895,671. Waveguides. IMPERIAL CHEMICAL INDUSTRIES Ltd., and BARLOW, H. E. M. May 9, 1958 [May 17, 1957], No. 15720/57. Class 40(8). Perturbation of the circular H 01  mode in a waveguide bend is prevented by decreasing the capacitance of the waveguide in the region of the outside radius of the bend. This may be done by filling a straight, circular - section waveguide with cellular polystyrene or cellular polyethylene and then bending it. The consequent distortion of the cellular dielectric results in a decreased permittivity towards the outside of the bend. In a modification, the waveguide is filled with discs 7, Fig. 4, of cellular dielectric. Bending the waveguide has the effect of increasing the spacing between the discs at the outside of the bend. The waveguide of Fig. 5 is made of conductive rings 9 spaced by metal springs 13 and enclosed within a rubber tube 11. The slots between the rings are loaded with rings 15 of titanium dioxide in a polythene binder. Bending the waveguide has the effect of increasing the spacing between the rings at the outside of the bend.

Title: Process for producing cyclopentene from dicyclopentadiene
IPC: C07C5/05
Filed: 1954-05-27
Abstract: Cyclopentene is obtained by converting dicyclopentadiene into monocyclopentadiene by vaporization or catalytic treatment and continuously passing the monocyclopentadiene in vapour form and at substantially normal pressure and in the presence of the theoretically required quantity of hydrogen over a fixed-bed hydrogenation catalyst such as a nickel or cobalt containing catalyst.  The initial stage may be effected by passing the dicyclopentadiene through a tube containing iron filings which have been preheated to 150-200 DEG  C., or through a layer of high boiling saturated hydrocarbons at a temperature of 130-160 DEG  C., the resulting monocyclopentadiene being removed as a vapour. This vapour is then mixed with hydrogen and passed through a glass tube heated to about 120 DEG  C. and the issuing gases subjected to a heat treatment to dimerize the unconverted cyclopentadiene.  The cyclopentene is removed by distillation.

Filed: 1943-10-27
Abstract: 4-Amino-5-arylpyrimidines are made by heating together, at a temperature of at least 120 DEG  C., preferably 170-180 DEG  C., and under conditions which permit or facilitate the elimination from the reaction zone of water formed during the reaction, formamide and a benzyl cyanide of the formula Ar-CHR-CN wherein Ar represents a phenyl group optionally bearing simple substituents such as alkyl, halogen, hydroxy, alkoxy or nitro and R represents hydrogen or one of the groups -CH = NH, -CH = N-aryl, -CHO or -CO-X, X representing alkyl, alkoxy, aralkyl or aryl.  The reaction may be carried out in a vessel provided with a reflux condenser so adjusted that it allows water to escape but retains the formamide.  It may also be effected in a stream of ammonia gas, and solvents, e.g. excess formamide, may be used.  Where an a -iminomethylbenzyl cyanide is used as starting material it may be generated in situ from the benzyl cyanide and formamide.  In the examples benzyl cyanide or its a -formyl, -acetyl, -iminomethyl, -phenyliminomethyl or -carboethoxy derivatives and formamide yield 4-amino-5-phenylpyrimidine, p-chlorobenzyl cyanide and formamide yield 4 - amino - 5 - p - chlorophenylpyrimidine, p-hydroxybenzyl cyanide and formamide yield 4-amino-5-p-hydroxyphenylpyrimidine, o- or p - methoxybenzyl cyanide and formamide yield 4-amino-5-o- or - p - methoxyphenylpyrimidine and a  - phenyliminomethyl - p - nitrobenzyl cyanide and formamide yield 4-amino-5-nitrophenylpyrimidine.  Other benzyl cyanides specified are p methyl- or -nitro-benzyl cyanide and a -benzoylbenzyl cyanide. Specification 570,528 is referred to.

Abstract: 1,221,779. Casting composite battery-plate connectors. ELECTRIC POWER STORAGE Ltd. 5 April, 1968 [6 April, 1967], No. 15845/67. Heading B3F. [Also in Division H1] In a lead-acid electric storage battery, a plate strap 25, Fig. 3, is cast in a recess 12 or 14, Fig. 1, in the upper part 11 of the wall of the battery container 10 by pouring molten Pb into the recess when lugs 21 of plates 20 to be joined have been inserted through grooves 15 into the recess. Each recess 12, 14 has the grooves 15 formed in its inner wall and the latter may be a separate masking strip (40) with slits so that it can be threaded over the plate lugs 21; it may be a steel comb (50) to be removed after casting. The straps 25 cast in longer recesses 12 are also intercell connectors while those in short end recesses 14 are cast using a temporary mould (27) to form a reduced top 28, Fig. 5, for a terminal connection. A lid 30 of the battery has terminal posts 31, Fig. 3, each with a connector portion 32 with a notched or slotted end over (or interdigitating with a notched end of) an end strap top 28 in a recess 14 when the lid is in position. Pb is poured through an opening 33 in the lid to unite the plate strap and connector, after which the opening 33 is filled with an epoxy resin or other cement 34. When the inner wall of a recess 12 is temporary, i.e. when steel combs (50) are used, the edges of the latter are formed to receive the broadened end of an intercell partition (51), Fig. 7 (not shown), but leaving a gap to form a fillet (56) of Pb for sealing the partition. The edge of the intercell partition may be grooved or corrugated so that sealing ribs are formed when the intercell connector is cast. The plate lugs 21 may extend horizontally from the sides of the plates 20 where the acid can extend above the grooves 15.

Abstract: 439,288. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Smith, R. M. ; Marlton Pike, Merchantville, New Jersey, U.S.A.) May 29, 1934, No. 16035. Convention date, June 30, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 30, 1934.] [Class 40 (v)] A diode-amplifier valve is used in a receiver as a carrier frequency amplifier, a diode detector and as a modulation frequency amplifier by reflexing to keep the size, current consumption, cost and number of valves as low as possible. A receiver for use in motor cars or the like comprises a supersonic heterodyne circuit in which the intermediate frequency amplifier 28 is of the screen grid or pentode type as shown in Fig. 1 and includes one or more diodes for rectification. A reflex circuit is used and the intermediate frequency valve is used also as an audio frequency amplifier. The diode load comprises resistance 57 and the portion of potentiometer 59 below the slider 58 and is connected by shielded lead 61 to the low potential side of the intermediate frequency input circuit 37, and provides automatic volume control over lead 64. In a modification, Fig. 2 (not shown), a separately biassed diode is used for the automatic volume control so that this is delayed. In a further arrangement, Fig. 3 (not shown), similar automatic volume control is used but the voltage may be taken from a potentiometer tapping which may be conjointly operated with the audio-frequency volume control. In this arrangement one end of the volume control potentiometer is earthed and the potentiometer is connected in parallel with part of the load resistance through condensers while a condenser between the tapping and earth provides simultaneous tone and volume control. In a further modification, Fig. 4 (not shown), the potentiometer serves as the diode load and provides the grid bias for the amplifying valve. The Specification as open to inspection under Sect. 91 comprises also a switch in the modification, Fig. 4 (not shown), so that all the voltage or only the portion of the voltage between the potentiometer tapping and earth may be used for automatic volume control. Fig. 5 (Cancelled), shows an arrangement in which the volume control potentiometer 128 regulates both the audio frequency passed from the anode circuit of the valve 28 to the amplifier 160 and the transfer of intermediate frequency energy from the anode circuit to the detector circuit. Thick lines show the diode detector circuit and the reflex path for the audio signal. Fig. 6 (Cancelled), shows a modification in which the same volume control is used as previously for high frequency but the audio frequency potentiometer 128 is in the grid input circuit to the amplifier 160 instead of providing the audio frequency anode load of the valve 28 which avoids distortion due to the reduction of the anode load. This subject-matter does not appear in the Specification as accepted.
