Title: Power transmission mechanism
IPC: F16H61/02
Filed: 1929-12-05
Abstract: 350,378. Variable-speed gearing. RIPLEY, H. E., Prestbury Court, Prestbury, Gloucestershire. Dec. 5, 1929, Nos. 37286, 37885, and 39259. [Class 80 (ii).] A variable restraint is imparted to the reaction member h, Fig. 1, of an epicyclic train comprising a driving planet carrier uu and variably driven sun gear and shaft / by applying force to centrifugal masses n in opposition to centrifugal force. The masses n are carried with slight radial play on pairs of pins l, Fig. 3, secured to discs o, j fast to the internally-toothed gear reaction member h. The controlling force is caused to act radially inwards without friction on the masses n by bell-crank levers p engaging recesses pa in the masses. The inner ends of the two levers p are subjected to thrust by rods r, a balancing ring s, pull-rods t, and sleeve u through a thrust bearing nb from lever w on arbor x. The angular position of arbor x which controls the speed of shaft f is varied automatically by the torque reaction on the rear axle casing c, Fig. 4, of a vehicle. The torque reaction of shaft f is transmitted upwardly through lever hh and spring strut e to a lever b extending parallel to a lever q fast on arbor x, a being the gear casing. Thus through a roller ll between these levers is transmitted the force which is passed on as an inward force on the masses n, such force varying with the load and governing the speed of the vehicle. The range of speeds is varied by adjusting the position of the roller ll from a control hand-lever nb.

Abstract: 324,200. Stovell, F. W. Dec. 28, 1928. Cases with internal horns.-Relates to portable or table gramophones in which the lid is provided with a horn. According to the invention, a sound-amplifying tube 18, of gradually increasing cross-sectional area, is located in the body 10 of the casing and is connected at its smaller end to the tone-arm 25, the larger end of the tube 18 communicating with the smaller end of the horn in the lid 43 when the lid is closed. The inlet opening 41 of the horn, and the adjacent end 20 of the tube 18 are surrounded by walls 42, 26 respectively, which fit one within the other when the lid is shut. The horn is formed by providing in the lid a curved partition 35 and a cover-plate 40 in which the opening 41 is made.

Suitable synthetic resins for making the tube and the plugs are: unplasticized or plasticized P.V.C., the polycarbonic ester of dihydroxydiphenyl propane, acrylonitrile - butadiene - styrene, high density polyethylene, a polyamide, polypropylene and acetal resin. When made of P.V.C., the tube may be encased in a sleeve formed of glass fibres bonded together and to the tube by an epoxy resin adhesive. The glass fibres may be in the form of a woven sheet or of an unwoven mat in which the fibres lie in the same direction helically about the tube.

Title: Improvements in and relating to prime mover control systems
IPC: H02P23/00
Filed: 1928-12-29
Abstract: 303,182. British Thomson-Houston Co., Ltd., (Assignees of Place, C. W.). Dec. 29, 1927, [Convention date]. Dynamos, regulating.-The fluid gate 7 of a water turbine 2 driving a generator 3, is controlled by a governor 15 driven by a motor 16 which is brought up to normal speed in advance of the generator 3, to allow for the usual lag in closing the fluid gate and so to prevent the turbine from over-running. For starting, the switch 23 is hand closed to energize the electromagnet 13, to move the gate closing spring 11 out of operation, so allowing the spring 12 to open the gate 7. In speeding up, a governor 24 closes contacts 36 operating an electromagnet to close the switch 27, thus connecting the motor 16 across an auxiliary source of power 25, and at the same time opening contacts 34 to break circuit to electromagnet 13, and allow the gate closing spring 11 to come into operation. When the motor 16 builds up a predetermined voltage, the relay 33 closes contact 38 and thereby re-energizes the magnet 13. As the turbine accelerates, the exciter 4 builds up, so closing switch 20 thus connecting the generator field across the exciter terminals, the switch 20 also closing contacts 41 energizing electromagnet 30 and operating switch 29 so that, when the generator voltage is above a predetermined value, switch 29 disconnects motor 16 from the auxiliary source 25 and connects it across the generator terminals. If the windings 21 or 30 become de-energized by exciter failure the switch 29 operates to reconnect motor 16 to the auxiliary source 25 to prevent the turbine from running away.

Filed: 1964-09-24
Abstract: Refractory structural and lining materials are made by pre-heating normal coarse-grained quartzite at a temperature above 500 DEG  C. and subsequently subjecting it to a hydrothermal treatment above 165 DEG  C.  For instance, lump form quartzite may be (1) heated to 1250 DEG  C. and crushed; (2) heated to 1250 DEG  C. and crushed to form a coarse and a fine grain fraction, the former being further heated to 1450 DEG  C. prior to mixing with the latter fraction; or (3) crushed and separated into a fine grain and a coarse grain fraction, the latter then being heated to 1250 DEG  to 1450 DEG  C. and mixed with the former.  The heating processes are carried out in conventional furnaces, e.g. shaft or fluidized bed furnaces.  The powdered, pre-heated quartzite is subjected to treatment with saturated or super-heated steam at above 165 DEG  C. for more than 65 "hours-atmospheres" (time in hours x atmospheres of pressure above atmospheric pressure) in an autoclave at, e.g. 10 to 20 atmospheres. Alternatively, the hydrothermal treatment is carried out at normal pressure and may be combined with the pre-heating of the quartzite by introducing steam into the pre-heating furnace. Lime milk may be added in a vacuum operation or the quartz may be saturated therewith in the autoclave.  The treated quartzite, mixed if desired, with fine grain untreated quartzite, is processed in known ways to form, e.g. ramming masses, bricks and other shaped articles.  In one method, pre-heated quartzite may be subjected to a preliminary hydrothermal treatment and/or mixed with lime milk, quartz powder, TiO2, spent sulphite liquor or molasses, prior to moulding, hydrothermal treatment and firing.
