Abstract: 960,310. Rotary piston engines. DAIMLERBENZ A.G. Jan, 31, 1962 [Feb. 1, 1961], No. 3681/62. Heading F1F. The apex sealing strip 5, Fig. 1, for the three-sided piston 3 of a rotary piston engine having a two-lobed epitrochoidal profiled casing 1, includes on its leading face 7, Fig. 2, a pair of grooves 8, Fig. 8, extending from the inner end face 9 for a distance of from to ¢ the height of the strip. The strip which is a loose fit in its radial slot 4 is initially braked by friction so that it cants, the grooves 8 permit gas under pressure from the chamber in front of the strip to pass beneath the strip to urge it radially outwards into sealing contact with the casing profile. With the pressure in the chamber in front of the strip greater than that in the chamber behind it the strip is subsequently pressed against the trailing face 16 of the slot 4. The strip on its trailing face 10 may also be formed with grooves 11, 12. The grooves 11 being similar to but staggered with respect to the grooves 8 and the grooves 12 extending from adjacent the tip 13. These grooves counteract any tendency for the strip to cant when the gas pressure behind the strip is greater than in front of it.

Title: Improvements relating to brake distributors having associated control reservoir charging valves
Inventor: SIMMONS ARTHUR WILLIAM
IPC: B60T15/18
Filed: 1962-01-31
Abstract: 984,964. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Dec. 21, 1962 [Jan. 31, 19621, No. 3708/62. Heading F2F. In a brake distributer the arrangement is such that simultaneously with the connection of quick service bulb pressure, or a pressure resulting from the charging of a quick service bulb, to one side of an element 13 to close a control reservoir charging valve 8, there is slowly applied at a predetermined rate a pressure derived from the above-mentioned pressure to the opposite side of the element. As shown, the control reservoir is connected to passage 9 and is charged when the valve 8 is open from a supply source such as the brake pipe connected to passage 4. Upon initiation of brake application quick service will occur and connect the brake pipe to the quick service bulb and compressed air will flow into bulb 2 and chamber 3 connected by passage 1 to the quick service valve. The diaphragm 13 will move to the left to allow the valve 8 to be moved on to its seat by the spring 6 to close communication between the control reservoir and the brake pipe. At the same time the compressed air will slowly flow into bulb 16 and chamber 15 through the restriction 17. If the brake application has not developed the spring 14 will open the valve 8 when the pressures in chambers 3, 15 are substantially equal to connect the control reservoir to the brake pipe, allowing the distributer to move to the brake release position. Chambers 3, 15 are vented (by means not shown). If the brake application does develop further apparatus (not shown) will cause the control reservoir to remain disconnected from the brake pipe due, for example, to the building up of brake cylinder pressure. In a modification the valve 8 is on the opposite side of the diaphragm 13 so that the latter either presses the valve 8 on to its seat or allows it to be moved off by the spring 6. In a further embodiment the brake cylinder is connected via a restriction to the chamber 3 and bulbs 2 and 16 are connected by means of check valves to a first bulb open to the atmosphre via a restriction.

Title: Improvements in or relating to polyphase oscillator and like circuits
IPC: H03B5/10
Filed: 1956-02-07
Abstract: 858,114. Valve oscillator and amplifier circuits; phase and frequency modulation. SALAM, H. P. A. Feb. 7, 1957 [Feb. 7, 1956], No. 3841/56. Classes 40(5) and 40(6). A circuit for producing two or three phase oscillations, for producing a phase modulated signal or for converting amplitude modulated wave to phase modulated wave comprises two frequency selective amplifiers and a source of oscillation of the centre frequency of the selective amplifiers the input to each amplifier being obtained by combining in a symmetrical T-network the output of the other amplifier and the source. Fig. 3 shows an oscillator comprising three amplifiers having tuned anode circuits, the output from each pair being combined in a T- network C1, C2 and fed to the input of the third amplifier. When the circuits are identical three phase oscillations are produced but when the output amplitude of one is less than the others the two equal amplitude oscillations are in phase quadrature and thus two phase oscillations are produced. In an alternative oscillator (Fig. 4) the amplifiers have frequency selective input circuits formed by the frequency selective arms of a Wien bridge (Fig. 5) and the T-networks coupling the outputs to the inputs are resistive and comprise resistors R3, R4. Lamps or thermistors I limit the amplitude of oscillation. Alternatively peak limiting diodes in the anode or screen circuits may be used for this purpose in both Figs. 3 and 4. One of the amplifiers may be replaced by an external source of oscillation (Fig. 2, not shown) in which case two or three or other phase related oscillations may be obtained from the circuit according to the amplitude of the external oscillation. If the external oscillation is amplitude modulated, phase modulated oscillations will be produced in the circuit. Alternatively phase modulated oscillations may be produced by this arrangement by having a constant value of external oscillation and modulating the output from one of the amplifiers. For example, in Fig. 6 which comprises two amplifiers V and a third source of oscillations XY the output from the left-hand amplifier is modulated by a source MI through a circuit RpT and a diode rectifier. If the modulation is suitably integrated before being applied to the transformer a frequency modulated oscillation is produced. Alternatively direct frequency modulations can be achieved using the three phase oscillator circuit of Fig. 3 in conjunction with a balanced modulator. It is suggested that grounded emitter transistors could be used in the circuit, operating under class c conditions where power efficiency is required.

IPC: C12P7/28
Filed: 1918-03-07
Abstract: 130,666. Ricard, E. Aug. 8, 1917, [Convention date]. Fusel oils; ferments.-Butyl alcohol and acetone are produced by fermentation of worts made from starchy materials by means of a special bacillus, named bacillus butylicus BF, found in animal refuse such as the liquid refuse of slaughter-houses. The bacillus, a description of which is given, is optionally anaerobic and is cultivated and isolated by ordinary methods. It can be used in worts which have been boiled with acid to aid liquefaction. Fig. 5 shows a plant suitable for carrying out the process. The material is mashed in a mash-tun B, boiled in a boiler C, and mixed with water to the proper degree of dilution in a mixer D. The material thus treated is heated by steam to a temperature of about 120‹ C. and raised by steam pressure to a reservoir E, whence it passes to the fermenting-vats G, G' through a heat-interchanger F, where it is cooled to 37‹ C. The hot water from the interchanger F is used in the mash-tun B and dilution vessel D. The fermenting-vats G, G<1> are provided with flexible connexions 20, whereby fermented liquid can be passed from one vat into another to start fermentation. An appropriate quantity is about 5 per cent. of the contents of a vat.

Title: Improvements in and apparatus for the clarification of liquids and the separation of finely powdered solid substances
IPC: B01D17/02
Filed: 1929-02-07
Abstract: 329,013. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 7, 1929. Surface-tension and like separating processes and apparatus.-A process for the calorification of liquids and the separation of finely divided solid substances comprises spurting one or more free jets of a suspension of one or more finely divided substances vertically on to the top of a column of clarified liquid from such a height that an ascending column of foam is produced which takes up and removes the suspended matter. The liquid to be clarified is spurted through a pipe a on to the top of the clarified liquid contained in a cylindrical vessel b whereby loam is produced and ascends over the top of the vessel b and escapes through an opening d. The clarified liquid collects in a vessel e and may be drawn off through one or more openings f. The openings f afford a, means of varying the level of the liquid in the vessel e and so of the height of the column of foam. The formation of foam is increased bv subdividing the inlet pipe a and also bv passing a gas through the column of liquid in the vessel b. The shape of the vessel b may be varied according to the foaming capacity of the liquid to be treated. e.g. it may be conical. The clarification mav be carried out in an atmos phere of any desired gas by fitting the apparatus with a hood h. The process may be used for the separation of finely-powdered solid substances which for this purpose are previously made into suspension ; bv the addition i.e. of oily materials some part of the solids may, be rendered capable of being wetted so that it is carried along with the foam while the other part collects at the bottom of the apparatus. Applications of the process are the removal of finely divided sulphur from solu tions, e.g. those formed in the removal of hydro gen sulphide from gases by oxidation with sulphur dioxide with the aid of a solution of ammonium thiosulphate; also the separation of the mixture of sulphur and iron oxide formed in the removal of hydrogen sulphide from gases by an alkaline suspension of iron oxide.
