Title: Improvements in multi stage steam engine plants
IPC: F01K3/24
Filed: 1937-10-27
Abstract: 486,395. Steam-power plant. BAUER, G. Oct. 27, 1937, No. 29385. Convention date, May 3. [Classes 110 (iii) and 122 (iii)] In a multi-stage steam-engine plant with intermediate superheating, a part or the whole of the live steam before it enters the H.P. stage is first highly superheated in a separatelyheated heater and is then passed through an intermediate superheater or several seriallyconnected intermediate superheaters through which the engine working steam passes, separated from the live hot steam, from one stage to the next below. In the three cylinder marine engine with exhaust turbine shown, the supply is first byepassed through a separately-heated superheater 11 and heated to 400-500‹ C. or more. This supply is controlled by a valve 12 and is led through an intermediate superheater 14 before passing to the H.P. cylinder by pipe 15. The steam from the I.P. cylinder 2 to the L.P. cylinder 3 passes in counter-current manner through the superheater 14. The superheater 11 is connected to the live steam pipe by valved branches 17, 18 with a valve 20 between them. The superheaters can be cut out and the engine worked with boiler steam. The valves 12, 19, 20, 23 may be set to supply steam direct and also through the superheaters. In a modi. fication, a superheater is also arranged between the H.P. and I.P. cylinders. In this case the first intermediate superheater is heated by steam and the second by combustion gases from the heater 11. In a third construction, the intermediate superheaters are heated by steam. These may be cut out and the cylinders directly connected. The primary superheater may be heated by liquid fuel or by the exhaust of an internal-combustion engine. The exhaust from the cylinder 3 passes to a turbine 4 which through a hydraulic coupling 5 and a doublewheel reduction gear 6 ... 9 drives the screw shaft 10 in common with the reciprocating engine.

Title: Improvements in shuttle checking and adjusting devices for looms
IPC: D03D49/36
Filed: 1924-12-09
Abstract: 244,905. Grosvenor, J. E., and Picking, W. T. Dec. 9, 1924. Shuttles, adjusting for picking; checking shuttles and pickers.-In order to arrest the incoming shuttle in a definite position before it reaches the outer end of the shuttle box to allow the shuttles boxes to move, an inclined surface b of an adjustable plate 3, Figs. 1 and 2, fixed to the framework A, is adapted to be engaged by a runner 7 on a plate 5 hinged to the lay C. A buffer 8 on the plate 5 is thus moved to engage the picking-stick 4 and move the picker to meet the incoming shuttle. When the lay moves forwardly to beat up the weft, the runner 7 moves down the inclined surface b and allows the picking-stick to move outwardly under the influence of the usual spring. The Provisional Specification describes also an arrangement in which the picking-stick engages the inclined surface directly, without the intervention of the hinged plate. The invention may be applied to the adjustment of pickers operated in the manner described in Specification 213,327.

Patent GB-637412-A (GB)
Title: Process of preparing benzene hexachloride
IPC: C07C17/02
Filed: 1947-11-05
Abstract: Benzene hexachloride is prepared by chlorination or benzene in solution in an inert solvent in presence of light at a temperature between the crystallization temperature of benzene and the crystallization temperature of the mixture of benzene with the solvent.  The latter is preferably carbon tetrachloride, and in this case the temperature range is 6 DEG  to - 47 DEG  C.  It is also preferred to use more benzene than corresponds with saturation of the solvent at the operating temperature, i.e. solid benzene will be present as a reserve.  The process may be operated in a continuous manner by the introduction of stoichiometric amounts of chlorine and fresh benzene into a mixture of benzene and inert solvent saturated with benzene hexachloride, and separation of crystals of C6H6Cl6.  In the examples: (1) a mixture of 70 per cent carbon tetrachloride and 30 per cent benzene is chlorinated at - 20 DEG  C. with a mixture of chlorine and carbon dioxide, and (2) the continuous process is exemplified using a solution of benzene in carbon tetrachloride at - 40 DEG  C. and a solution of chlorine in benzene at - 20 DEG  C. Specifications 619,677 and 626,705 are referred to.

Title: Improvements in folding machines for laundry purposes
Inventor: HOWLETT EDWARD JOHN
IPC: D06F89/00
Filed: 1952-11-22
Abstract: 723,507. Folding sheets &c. BRAITHWAITE & SON, ENGINEERS, Ltd., I. Nov. 23, 1953 [Nov. 22, 1952], No. 29562/52. Addition to 667,191. Class 42 (2). In a folding machine of the kind in which the leading edge of a travelling article is lifted and gripped and subsequently released to fall in register with the trailing edge, the raising of " timing " fingers by passage of an article causes clockwise rotation of a shaft A carrying an arm A<SP>1</SP> on which is mounted a blade B which normally holds a pawl C, carried by a pivoted lever P controlling lifting fingers, out of engagewith the teeth of a continuously-rotating ratchet wheel D ; rotation of shaft A moves blade B to allow pawl C to engage the ratchet teeth whereby the pawl and lever P are moved clockwise to cause the lifting fingers to grip and raise the leading edge of the article. When lever P has moved through about 90 degrees a pin E on pawl C engages a stationary cam F and disengages the pawl from wheel D, and the pawl is held in this position by engagement of its tail c<SP>1</SP> beneath a hook g on a lever G. A returnspring acting on lever P causes lever G to be lifted to the extent of a slot g<SP>1</SP>; a tooth k on a lever J, connecting lever G to a link H carried by lever A<SP>1</SP>, is thereby raised close to the ratchet teeth. When the trailing edge of the article passes the timing fingers the latter fall, lever A<SP>1</SP> rises to its initial position, and link H is raised to bring tooth k into engagement with the ratchet teeth; this causes lever J to be moved to the left and hook g to release pawl C which thereupon moves with lever P, under the action of the return-spring, back to its initial position against blade B. Pawl C is frictionally pivoted on lever P by an axially spring-loaded spindle Q so that it remains clear of the ratchet teeth on the return movement of P; on the pawl returning to its initial position, spindle Q is moved axially by a stationary cam so as to free the pawl from frictional grip and allow it to fall under gravity on to blade B, and, when the latter is next shifted, on to the ratchet teeth. The return movement of lever P releases the leading edge of the article so that it falls in register with the trailing edge.

Abstract: 785,096. Non-reciprocal microwave circuits. STANDARD TELEPHONES & CABLES, Ltd. Oct. 21, 1955 [Oct. 29, 1954], No. 30161/55. Class 40 (8). A non-reciprocal radio-frequency coupling device comprises a disc-shaped element 10 of ferrite disposed between two flat conductive spirals 5, 6 which are shaped and dimensioned to transform plane-polarized energy in the input and output lines A, B into circularly polarized energy for propagation within the ferrite element. The element 10 is conditioned by an adjustable electromagnet 11, 12 for gyromagnetic resonance at the operating frequency. Since, when viewed in the two opposing directions of propagation, the rotation of the wave is respectively in the same sense and in the opposite sense to that necessary for gyro-resonancelossless propagation takes place in one direction and complete attenuation in the other. The spirals 5, 6 are connected by conductive studs 9, 9a to the ends of narrow strip conductors 2, 2a which together with the comparatively wide ground conductors 1, 1a and the dielectric layers 3, 3a form input and output transmission lines of the " strip " type. The conductors 1, 1a are connected to the housing 4 of the coupling device. In a modification, Fig. 6, the coupler is completely enclosed within a housing 18 connected to the outer conductors 19 of rectangular input and output coaxial lines. The inner conductors are in the form of flat strips 20 centrally supported by spacers (not shown) or by a solid dielectric filling 21. Alternatively the input and output lines may be of the " sandwich " type in which a central strip conductor is disposed between a pair of comparatively wide outer conductors. Printed circuit techniques, using etching processes, may be used in certain cases to form the input and output lines.
