Patent GB-1165812-A (GB)
Title: Variable Phase Shifter
Inventor: AYER DONALD RODNER
IPC: H01P1/18
Filed: 1967-04-11
Abstract: 1,165,812. Phase shifters. SANDERS ASSOCIATES Inc. 11 April, 1967, No. 16607/67. Heading H1W. A phase-shifter comprises a length of transmission line having inner and outer conductors and means for interposing a variable length of a dielectric substance between the conductors. In the impedance-matching device of Figs. 7, 8, the inner conductor of a line 82 consists of strips 101 mounted on opposite sides of a generally circular dielectric disc 100 which is fixedly supported by waveguides 106, 108 forming the input and output of the device. Further strips 99, also mounted upon the disc, provide the inner conductor of an open-circuited stub line 80 connected to the main line at junction 116. The outer conductor of line 82 is provided by annular conductive members 86a, 86b spaced apart by blocks 86c, 86d and mounted for rotation about a central vertical axis upon bearings 88. The inner conductor of line 82 has a semicircular portion centred about this axis, and this portion lies between annular grooves formed in the opposed inner faces of members 86a, 86b. Corresponding semicircular halves of these grooves are filled with a dielectric material 112 and the other corresponding halves with a conductive material 114. Thus, by rotating the members 86a, 86b, the proportion of dielectric to conductive material surrounding the inner conductor of line 82 may be changed with consequent change in the electrical length of the line. The electrical length of semicircular stub 80 is changed in a similar manner. The outer conductor of the stub consists of a conductive annulus 120a, conductive semicircular members 122 and dielectric semicircular members 123, these members being mounted upon a cylinder 90 which can be rotated independently of the members 86a, 86b. Thus, the impedance presented by the stub may be separately adjusted and the combination of line and stub provides an impedance adjustable in both phase and magnitude. The Specification also describes a differential phase-shifter similar in operation to the impedance matching device. The two lines of the phase-shifter have complementary semicircular portions and rotate together within a conductive annulus forming an outer conductor. Circular grooves in the annulus opposite the semicircular lines are partly filled with dielectric material so that rotation of the lines virtually causes dielectric material to move from one line to the other. In the simple phaseshifter of Fig. 1, a U-shaped inner conductor 10 is mounted within a composite outer conductor consisting of a fixed base 12 and a slidable portion 16. The latter carries a pair of dielectric blocks 14 lying on either side of the inner conductor. The effect of sliding the portion 16 is to vary the amount by which the blocks overlap the base portion 10c of the inner conductor.

Fig. 2 (not shown), placed at a free height above the container bottom to allow air circulation from an air inlet 27 to an air outlet and ventilation tube 15 at or near the top 5 of the container. The insides of the walls 2 and 4 are all lined with inner walls 12 of compost resisting material and the inner and outer walls form air ducts between them allowing the air to circulate, the inner wall being provided with slots 14 allowing air to enter the compost. The grate tube 11 consists of a corrosion resistant covering (24) of P.V.C. over a metal tube (23) containing electric heating resistance wires (21) each within heat resistant coverings (22), the whole grate being connected with a transformer. The heater maintains a surface temperature of approximately 70C. On the top 5 there is a inlet 6 for toilet refuse having a tightly closeable seat and an inlet 7 for kitchen garbage having a tightly closeable cover. To accelerate the starting of the mouldering process a bag filled with a mixture of dry mull and topsoil and perforated to let in air may be placed on the grate. As the material moulders it passes through the grate and falls into the cases 1a 1b and 1c from where it may be removed.

Filed: 1956-06-01
Abstract: An emulsifying agent comprises a salt of a higher molecular-weight straight-chained aliphatic or cycloaliphatic amine which contains at least one hydrocarbon chain of 8 or more carbon atoms and a polybasic organic acid.  The amines are derived from naturally-occurring fatty- or resin-acids; from paraffins, their halo genation or oxidation products and from alkylated aromatic amines.  Particularly exemplified are primary amines corresponding to the composition of tallow or coconut fatty acids, octadecylamine and hexadecylamine. Examples of acids are oxalic, succinic, adipic, pimelic, sebacic, dimethyl - succinic, tartaric, citric, phthalic and malonic. Emulsified are mineral oils, "Vaselines" (Registered Trade Mark), paraffins, vegetable and animal fats or fatty acids, waxes, fatty alcohols, spindle oil, xylene, thin mineral oil, paraffin oil, white spirit and toluene. The emulsifier of the invention may be combined with other cation-active or non-ionic emulsifiers, e.g. with the acetates or hydrochlorides of higher molecular weight amines, addition products of ethylene oxide to high molecular weight alcohols, amines or carboxylic acids, and are of particular advantage when combined with low molecular weight monocarboxylic acids such as glacial acetic acid.ALSO:Salts of higher molecular weight straightchained aliphatic or cycloaliphatic amines which contain at least one hydrocarbon chain of 8 or more carbon atoms and polybasic organic acids are used as emulsifying agents.

Abstract: 688,523. Pulverizing units. BABCOCK & WILCOX, Ltd. July 20, 1951 [July 24, 19501, No. 17251/51. Class 59. In a beater mill in which classification is effected by entrainment of particles by gaseous fluid flowing through the mill housing towards an axial outlet, the peripheral speed of the rotary beater means of the mill is adjustable to control the particle size. In the form shown, pairs of oppositelydirected beater arms 13 to 16 are slidable within apertures 17 to 20 in the mill shaft and include racks engaged bv the opposite sides of pinions 9 to: 12 mounted on a manually-rotatable spindle 8. Rotation of the spindle projects the beater arms outwardly or withdraws them inwardly. Removable beater heads 21 are mounted on the ends of the beater arms. An inlet 2 is provided for the passage of air and the material to be pulverized. A fan rotor 28, 29 mounted on the mill shaft 3 draws the air and entrained particles from the housing 1 through an outlet formed by the annular space between the shaft and a baffle ring 30 into a fan housing 31 provided with an outlet 32. The outlet from the housing 1 may be provided with an adjustable throttling device. The peripheral speed of the rotary beater means may be adjusted by their being driven through a hydraulic variable-speed coupling or variable-speed power transmission means or by a variable-speed motor. In the latter case, the fan rotor is driven at a constant speed from a separate motor. The mill may be 'used 'for effecting direct firing of a furnace with pulverized fuel.

Title: Improvements in or relating to selecting switches for use in automatic telephone or like signalling systems
IPC: H01H63/22
Filed: 1940-12-04
Abstract: 545,634. Automatic exchange switches. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., BAKER, G. T. Dec. 4, 1940, No. 17271. [Class 40 (iv)] A selector for non-numerical or numerical use is given a step-by-step movement in which the motion is rapid between and slow over the contacts with the aid of a cam member and a constantly running shaft driven by an individual or common motor. In the arrangement shown in Fig. 1, the initial operation of the impulse relay 22 removes a catch 20 from a stud 18 on a cam 11 which is then turned by a spring 16 until another stud 23 engages the catch. The release of 22 by a selecting impulse frees this stud and the cam is then forced into engagement with a constantly running disc 10 of hard rubber and rotates until it is stopped by engagement of stud 18 or 23 with the catch 20 according as the impulse has not or has terminated. In rotating, the cam lifts pawl 24 to drive a ratchet-wheel 25. If the switch is to be used for hunting, stop 23 is omitted. In a modification, the pawl is driven by a cam-shaped driving member 10 independently of the roller 11. In a further modification, in which the ratchet-teeth are preferably as shown in Fig. 5, the driving pawl, which is reciprocated as a whole as in the previous arrangement, is provided with a pivoted driving end 33, Fig. 7, this end being controlled by a subsidiary cam 34 so as to engage the ratchet wheel during the driving stroke and to clear it during the return stroke. In another arrangement not described in detail a Geneva stop mechanism is used.
