Title: Improvements in or relating to centrifugal couplings
IPC: F16D25/065
Filed: 1956-11-14
Abstract: 824,684. Friction clutches. TWIFLEX COUPLINGS Ltd., and FREEMAN, K. J. Nov. 14, 1957 [Nov. 14, 1956], No. 34876/56. Class 80 (2). In a centrifugally engaged clutch for use e.g. between a diesel engine and a compressor, centrifugal shoes 23 are carried by the driven member 12 and operator-controlled pneumatic, hydraulic, electric or mechanical means are provided to move the shoes into contact with a driving drum 10 to initiate drive. The shoes 23 pivot on the driven member 12 through links 19 with rubber bushes at both ends, the torsional resistance of which biases the shoes out of engagement. In Fig. 1, engagement is initiated by supplying pumped fluid pressure to act outwards through pistons 30, levers 33 and spring-returned plungers 35 on two of the four shoes 23. Centrifugal force on the shoes 23 maintains engagement after release of the fluid pressure. If the driven member is stopped, e.g. by jamming, the clutch disengages. In Fig. 4, fluid pressure supplied through a tube 64 and passages 60 acts through a piston 45, cam member 54, balls 52 and plungers 50, 56 to expend the shoes 23 into engagement with the driven drum 10. The shoes 23 are link pivoted, as before, to a member 43 fast on the driven shaft 59 on which the operating cylinder 44 is screwed. According to the Provisional Specification, the torsional resistance of the rubber brushes may bias the centrifugal shoes into engagement, in which case the operator controlled power means retracts the shoes.
Patent GB-430348-A (GB)
Title: Improvements in a method of aerating liquids
IPC: C12M1/06
Filed: 1933-12-11
Abstract: In devices for aerating liquids, especially in yeast fermentation processes, a hollow body serving for supplying air to the liquid, of such shape as to offer small resistance in the direction of movement, is moved through the liquid with great velocity relative thereto in such a manner that the air escaping from comparatively large openings is broken up at the moment of its contact with the liquid into very fine bubbles.  Preferably, the air escapes from the hollow body in a direction deviating from the plane of movement of the body, for example, perpendicular or approximately perpendicular thereto. Guiding blades may be arranged in the outlet direction of the air, preferably below the rotating member.  The Specification as open to inspection under Sect. 91 conprises also drawings of apparatus embodying the principles of the invention.  According to these drawings, the rotating body may have four arms with perforations which do not extend as far as the axis.  Guidling blades are provided below the rotating body, and a telescopic guiding cylinder may also be arranged coaxially about the axis of rotation in order to render the process of aeration more efficient.  To assist the action of the guiding plates, the cooling device for the work may be constructed as a vertical or horizontal tube system, one arrangement of which is shown.  In one form of rotating member having a large number of vanes, the parts near the axis are constructed to form screw blades. This subject-matter does not appear in the Specification as accepted.

Title: System for and method of generating and distributing electrical and thermal energy
IPC: H02J3/00
Filed: 1975-08-22
Abstract: 1512104 Power supply systems SAVCO Inc 22 Aug 1975 [26 Aug 1974] 34914/75 Heading H2H A system for electrically generating electrical and thermal power comprises a central elecelectrical power station 10 and local user installations A, B, C having loads 24 requiring electrical power and loads 28 requiring thermal power, each user installation including an engine driven power generator 30 and means to feed any locally generated electrical power not used at the respective user installation to power distribution lines 12 for use elsewhere. The user installation A, C may be private houses with electrical loads 24 such as lights, heater elements of heating or cooking appliances, motors in refrigerators, &c. and thermal loads 28 such as space heating systems and hot water heaters. When the room temperature in the house is low, a thermostat 40 energizes a relay which connects power from the lines 12 to a motor in the generator 30. The motor starts a water cooled deisel engine which then drives the motor as a generator to supply power to the electrical load 24 whilst the heat supplied to the engine cooling water is circulated to the thermal load 28 such as a hot water radiator system. If the local user installation generates more power than is required by the electrical load 24, the excess power is fed to the distribution lines 12 via a two-way watt-hour meter 20 which registers the net power supplied to the user installation.

Title: Resinous condensation products of 3:5-substituted phenols with aldehydes and method for their production
IPC: C08G8/28
Filed: 1953-12-16
Abstract: Permanently fusible and soluble resins are prepared by condensation of 3,5-diisopropyl phenol and an aldehyde such as formaldehyde, benzaldehyde, crotonaldehyde, furfural or acetaldehyde.  The products may contain less than one or from one to two molecular equivalents of aldehyde and may be produced with or without an acidic or alkaline catalyst such as sulphuric, hydrochloric, phosphoric and oxalic acids and sodium, potassium, calcium and quaternary ammonium hydroxides. In examples the components are refluxed and the resulting products may be neutralized, e.g. with line or hydrochloric acid, and dehydrated in vacuum before separation of the resin.  The products are soluble in or miscible with acetone, benzene, drying oils, waxes, gums, resins, varnishes and plasticizers and remain fusible even when heated with curing agents such as hexamethylene tetramine or paraformaldehyde.  These condensation products, however, act as curing agents for resins such as phenol-formaldehyde novolaks, as cross linking agents for polyene or polydiene rubbers and they are useful as plasticizers for thermosetting phenolic resins. Specification 751,598, [Group IV (b)], is referred to.

IPC: G03C7/14
Abstract: 350,481. Colour kinematography. GROVES, W. W., 30, Southampton Buildings, London.-(I. G. Farbenindustrie Akt.- Ges. ; Frankfort-on-Main, Germany.) March 11, 1930, No. 7915. [Class 98 (ii).] In taking kinematograph pictures in natural colours on linear lenticular films in a camera provided with a lens filter comprising parallel bands of different colours, the lens aperture is varied, in order to regulate the exposure, by masking out only the central portions of the filter bands. The appearance of dominant hues is thereby prevented, even if the filter is not disposed in the plane of the diaphragm of the lens. The different colour bands may be masked to different extents, the masked areas being, for example, of rectangular, circular or elliptical shape. Reference is made to a known method of varying the lens aperture by masking the end portions of the various colour bands of the filter.

Abstract: 173,158. Hart, H., (Mergenthaler Linotype Co.). Dec. 13, 1920. Assembling and distributing matrices ; magazines ;keyboards.-In order to permit the use of larger matrices, than usual without widening of the magazine the number of matrices in the fount is reduced and the additional space obtained is divided among the remaining channels of the magazine. The fount may be reduced, for axample, from 90 to 72 characters, the omitted characters being combined letters, such as fi, fl, ffi, &c. The magazine-channels are preferably spaced apart unequally at both their upper and lower ends, and the additional space is divided amongst them in proportion to the set-width of characters, of the largest fount. The magazine .entrance partitions and the tooth-combinations of the distributor-bar C, Fig. 6, are also reduced in number and unequally spaced. To render the new founts interchangeable with old founts, nearly all the characters are provided with the same tooth-combinations as heretofore, and the combinations on the distributor-bar C agree in most cases with those of the old bar V. Certain combinations are omitted from the bar, and others are transposed so that the combinations form a. series of groups within which the combinations occur in proper sequence. The ribs a<1>, which form the magazine-channels are bevelled at their upper ends to different extents so as to make the upper ends of the channels of uniform width. The partitions d of the magazine-entrance are provided with guiding-flanges d<1> to engage the ears of the matrices and, to prevent turning of the matrices in the wider channels, the flanges are formed on tongues d<2> secured to the partitions. The keys E Fig. 1, are reduced in number to correspond with the magazine-channels and are spaced apart at greater distances than usual. The escapementreeds E<2> are inclined slightly to co-operate with the unequally-spaced escapements. The frontplate or raceway B has a reduced number of partitions which are re-arranged to correspond with the magazine-channels. The magazine may be divided transversely into two sections 1<A>, 2<A>, which are independently removable. The topplate of the upper section has a hinged portion a<4> tu prevent damage owing to matrices becoming lodged between the two sections. The divided magazine may be used in connection with a column of ordinary magazines, and supplementary magazines, having a small number of channels and a separate, keyboard, may be arranged at the side of the main magazines.

Title: Improvements in or relating to electromagnetic waveguide devices
Inventor: ROGERS JOHN NEVIL
IPC: H01P1/365

Abstract: 838,149. Waveguide resonance isolators. GENERAL ELECTRIC CO. Ltd. Nov. 11, 1958 [Nov. 11, 1957], No. 35135/57. Class 40 (8). A resonance isolator comprises a number of rods 2 of ferrite arranged to lie parallel to the narrow walls of a waveguide 1 at a position where the magnetic field of the propagated energy is circularly polarized. Pole pieces 8, 9 provide a steady magnetic field of magnitude sufficient to cause gyromagnetic resonance at the signal frequency. The rods may be square, rectangular or circular in cross-section and may be glued to a lamina 4 of polystyrene which is mounted upon metal rods 5 whereby it may be transversely adjustable in the guide. In order to compensate for transverse displacement of the region of circular polarization in the vicinity of the ends of the group of rods, the spacing of the rods from the adjacent narrow wall of the guide may be non-uniform. Alternatively, compensation may be effected by dielectric loading or by a variation in the strength of the magnetic field towards the ends of the group. The bandwidth of the device may be broadened by making alternate rods of different ferrite material and staggering the rods slightly along the waveguide. The rods may be spaced from the broad walls of the guide and need not be perpendicular to these walls.

Feedwater, heating. - Distillation plant for making up boiler feed comprises a series of feedwater heaters connected so that vapour from the still may be condensed in any of the heaters at will. To increase the output of the still at peak load, the vapour is passed into a heater which is at a, lower temperature. The feedwater is circulated from the main condenser K of a turbine T through heaters C, B. Normally, the heater C is heated bv steam drawn from the turbine at LI, and the vapour from the evaporator A is condensed in the second heater B. At peak load, a connection L3 is opened by a cock D2 and the pipe L1 is shut off. The vapour then passes to both heaters, and the output of the evaporator is increased without raising the final temperature of the feedwater.
