Title: Improvements relating to microwave phase-shifting devices
Inventor: WHITMORE EDWARD JOHN
IPC: H01P1/18
Filed: 1954-02-17
Abstract: 756,192. Microwave phase-shifting circuits. FERRANTI, Ltd. Feb. 14, 1955 [Feb. 17, 1954], No. 4613/54. Class 40 (8). A microwave phase-shifting device for a transmission system in which the transmission path is required to have one or other of two electrical lengths according to whether the power transmitted is above or below a certain level comprises a waveguide " turnstile " junction with a gas discharge cell in the circular-section branch. The turnstile junction comprises four similar rectangular guides 11, 12, 13, 14 assembled with their broad sides in the same plane to form a rectangular cross from the centre of one side of which extends a circular guide 15 with its axis normal to the broad sides of the rectangular guides. The circular guide 15 contains a circular sealed resonant aperture 16 and a short-circuiting disc 18 the space between these elements being filled with an ionizable gas. The guides 12, 14 are shortcircuited at distances from the junction which differ by a quarter-wavelength of the transmitted energy. Half the energy arriving at the junction from the input guide 11 is coupled directly into the circular guide 15 whilst the remaining half divides equally between the guides 12, 14. These two components are reflected back to the junction in antiphase and are coupled into the circular guide 15. The wave energies coupled directly and indirectly into the guide 15 are plane-polarized in mutuallyperpendicular directions. The positions of the short-circuits in guides 12, 14 are preferably arranged so that the direct and indirect components are in phase quadrature and produce a circularly-polarized wave in the guide 15. This wave is reflected either at the aperture 16 or at the disc 18 according to whether its energy is sufficient or insufficient to cause discharge of the gas cell. Thus for a path difference of a halfwavelength between high- and low-energy wave the distance between the aperture 16 and the short-circuit 18 is made equal to a quarterwavelength. The whole of the output appears in guide 13. In a modification the guide 15 is extended axially to form a reservoir for the gas cell, the disc 18 being provided with a small communicating aperture. The Specification refers to a known arrangement for achieving the above results in which the input energy is divided equally between two branch guides having matched cells and short-circuits beyond the cells.

Title: An improved method of making chlorhydrins
IPC: C07C29/66
Filed: 1932-02-18
Abstract: In the preparation of chlorhydrins from gaseous chlorine and olefines in the presence of water, the production of olefine chlorides is checked by maintaining the olefine in large excess over the chlorine, e.g. about 8 volumes of olefine to 1 volume of chlorine.  It is preferable to start with pure water and to continue until a certain concentration of chlorhydrin, for example 20 per cent, is attained. Excess of olefine may be returned to the process.  When the inert constituents have accumulated considerably, the olefine may be concentrated again by known methods of gas separation.  In a modification of the invention, intimate mixture of water and olefine is passed through a suitable apparatus and chlorine is added at various points, but so that the olefine is always present in excess. The reaction temperature may vary within wide limits, and the reaction may be effected at atmospheric, increased, or reduced pressure.  Examples are given of the preparation of ethylene and propylene chlorhydrins at 20 DEG  C., the reaction heat being removed by cooling.  It is indicated that the use of equivalent proportions of olefine and chlorine yields a much greater proportion of olefine chloride.  The Specification as open to inspection under Sect. 91 (3) (a) states that the last traces of olefine may be removed by treatment with chlorine in equivalent proportion.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to gear changing mechanisms
IPC: G07F15/08
Filed: 1937-02-18
Abstract: 492,522. Prepayment mechanism for meters. BRITISH SANGAMO CO., Ltd., BUTHERUS, F. R., and WESTON, G. E. Feb. 18, 1937, Nos. 4945 and 14437. [Class 27] [Also in Groups XXIV and XIX] Price-changing mechanism.-Idler pinions 21, 14 are spaced round the periphery of cages 22-23, 15-16 so that gear-changing may be effected solely by rotation of a cage, which is coaxial with one stack of gears, 11 or 13, which stack is thereby connected by said pinions with another stack 20 or 10. The changes occur in small steps, the drives from the two sets of gears being combined by a differential 24, Fig. 2 ; one set gives steps which are multiples of those of the other set, and the drives may be added or subtracted by inserting a reversing device between'the driving wheel 9 and the stack 10. The invention is specially intended for use in price-changing devices in electricity prepayment meters. To change the price, a screw-driver is inserted in the slotted head 32 or 33 according to whether the change is in pence or in fractions of a penny. Assuming the former, the spindle 36 is pushed in against a spring 41 to move, by means of a spring 43, a bell-crank 42 to engage between the teeth of a planet carrier 26. This prevents the unwinding of any stressed spring in the prepayment device. In the case of the fractional device, the movement of the spindle 46 moves the spring 40 flush with the arm 39 and then the arm to move the spindle 36 and thus the bellcrank. When the screw-driver in the head 32 is rotated it turns the wheel 34 and thus the cage 15-16 which is held in the position desired by a spring detent 50. Spring wires fitted in one case to a distance piece of the cage, and in the other to the plate 2 lock the corresponding sun wheel of the differential to prevent one sun carrying the other, when set at zero, round with it. With a reversing mechanism added to the gears, it is only necessary for the device 10, 13 to have ratios corresponding to 2d., 4d., and Gd. Suitable gearing is shown in Fig. 4. A lever 106 pivoted at 97 carries sets of pinions, 99, 100 and 101-3, and an extension 98 in the path of pins 93-5 on a member 92 fixed to a sleeve 91 carried by the cage 22, 23. When a pin engages the extension 98, the arm is moved about its pivot so that the drive passes from one set of pinions to the other and is thereby reversed. A mask 107 covers one of two scales on an indicator 108.

Title: Improvements in or relating to machines for moulding dough and analogous plastic substances
IPC: A21C3/02
Filed: 1948-02-20
Abstract: 647,424. Molding dough. JESSON, L. E., and JESSON, G. A. Feb. 20, 1948, No. 5083. [Class 87 (ii)] A dough piece D is sheeted between a roller 14 and the upper run 2a of an endless belt 2, the sheet is coiled by a device 15, and the coil is rolled between the belt run 2a and the lower run 1a of an endless belt 1. The belts run between a frame comprising side-plates 3, 4. The coiling device is pivoted at the end remote from the dough-entry end on a shaft 21 carried by cranks 22 which are adjustable to vary the height of the discharge end of the coiling device. The device may be mesh-like, but, as shown, is grid-like, comprising longitudinal metal rods 16 and transverse metal rods 17 welded together; its dough-engaging end is supported in its lowermost position by a post 20 secured to a bar 19 which rests on the frame, the arrangement allowing the device to rise as the coil grows. The dough-engaging end is flared. The roller 14 has a concave peripheral surface and its shaft 24 is mounted in slots 34 in the frame. The roller may be adjusted vertically by rocking an arm 31 pivoted on an axle 32 and having an eccentric pin 29 engaging a slot 28 in one of a pair of arms 26 which carry the roller shaft 24 and are pivoted at 27. The handle 31 is fixed in position by nut-and-spring means 33. A convex knife 23 which scrapes the roller 14 is fixed to the arms 26 and hence moves with the roller as a unit. The belt 1 passes around rollers 43, 44 having spindles 41, 42 mounted in spaced bars 45, 46. The spindle 41 is journalled in the frame and the belt assembly pivots clockwise about this spindle as the coiled dough passes thereunder and raises it. Means are provided for reducing the load exerted by the belt assembly on the dough during the first part of the travel of the dough between the belts 1, 2, and increasing the load for the remainder of the travel. Such means includes a weight (not shown) attached to a chain, rope, &c. 52 passing over a sprocket 53 and attached to an arm 49 fulcrummed at 50. The arm 49 carries a hook 51 which engages a rod 47 fixed to bars 45, 46 and initially resting in slots 48 in the frame. At first the chain tends to pull the arm upwardly, thus taking some weight off the dough, but when the arm has risen a certain distance it contacts a stop (54, Fig. 2, not shown) provided on the chain above the end 49a of the arm and thus takes up the weight, which thereupon opposes ascent of the arm. The belts 1, 2 and the roller 14 are driven by an endless chain 12 and sprockets from an electric motor.
