Title: Improvements in direction-indicating and warning devices for motor road vehicles
IPC: B60Q1/34
Filed: 1925-12-21
Abstract: 263,301. Widmer, H. A. Dec. 21, 1925. Illuminated stencil and transparency indicators. -The circuits of lamps illuminating indicating arrows 6, 7 are controlled by a switch having a delay action. The switch, which is shown in Fig. 4, comprises a sliding member 36 that closes one or other pair of contacts 37, 38 and moves one of the pistons 42 against the pressure of a spring 44. The rate at which the piston returns may be controlled by a valve 46. The signal casing, is preferably of triangular form and a cutout triangle 3 may be illuminated when the brake is applied, while the form of the casing indicates that the vehicle is fitted with four-wheel brakes. The brake-rod 29 pushes a rod 20 against the action of a spring 21 and allows a light spring 25 to propel a collar 24 against a stop 26. The collar closes contacts 27, 28 to close the warning circuit.

IPC: G01F15/02
Filed: 1967-07-13
Abstract: 1,202,912. Measuring flow rate, electrically. MERCURY ELECTRONICS (SCOTLAND) Ltd. July 12, 1968 [July 13, 1967], No.32212/67. Heading G1N. Apparatus for measuring the flow of air in and out of the lungs of a human being or animal (i.e. the "minute volume" or the product of the size of individual breaths and the number of breaths per minute) comprises a micromanometer 9 for generating a D.C. signal representing the magnitude and direction of the pressure difference across a gauze member 4 and a relay P/3 which is energized when the flow is inwards to close contact P1 to apply said signal to an integrating circuit 14, 15 which charges capacitors 20, 22 to a potential representing the integrated value of said pressure difference and a discharge network 25-28 for the capacitor 20 so that when the direction of flow is not inwards the potential on the capacitor 20 falls linearly with time and a switch Q2 which is closed when flow inwards is resumed to charge capacitor 18 to the potential then on capacitor 20 whereby meter 19 indicates the "instantaneous minute volume". An adjustable potentiometer 23 allows a bias voltage to be set to compensate for the dead space (volume of air in mouth and other spaces not taking part in gas exchange). A changeover switch may be provided so that the capacitor 20 can be charged at each inspiration to a constant voltage whereby the indication is then proportional to the instantaneous respiration rate. The apparatus may be used to measure consumption of intermittently injected fuels.

Abstract: 485,660. Rotary engines. COLEMAN, C. J. Nov. 25, 1936, No. 32251. [Class 110 (ii)] The engine or pump has a disc k rotating with a shaft i, and one or more vanes q passing through slots at right-angles to the disc, the latter having line contact at l on the conical side walls. The vanes are flanged at the inner ends x to fit into slots in the disc, the flanges holding the vanes against centrifugal thrust to lessen the rubbing of the vane tips against the casing wall c. Sealing strips m, adjustable by screws n, are provided as shown. Inlet and outlet conduits r, s are positioned in the side walls d, e. The latter have undulating surfaces to compensate for the change in relative angular position of the vanes and walls. Grooves may be formed in the surface of the sphere h to accommodate the flanges x.

Title: Improvements in and relating to the preparation of hop extracts
IPC: C12C3/08
Filed: 1960-09-20
Abstract: In a hop-extraction process throughout which air is excluded and the temperature is substantially room temperature, dry hops are supplied from a charging hopper 1 to extraction vessel 2 which is fitted with a high speed vertically adjustable dispersing device 3 (peripheral velocity of dispersing head at least 2m/sec., preferably 15m/sec.) and treated for a short time with one or more bitters and soft resin dissolving solvents (e.g. ether, ether/alcohol, petroleum ether, hydrocarbons, methylene dichloride, isopropylchloride, dichloroethylene, trichloroethylene and perchloroethylene) supplied from tank 4, while simultaneously being broken up and dispersed by device 3. The mass is suction filtered in filter press 5 and the solvent re-circulated via pipe 8 for re-use with a further 2 to 6 hop batches.  After extraction of several hop batches, the concentrated hop-extract is collected in tank 10 and passes to a pre-evaporater 14 for inspissation in vacuo at 30  DEG C.  The removed solvent is condensed and passes to tank 18.  The concentrate from 14 is pumped to a thin-layer evaporator 22 for the removal of residual solvent which is returned to tank 18. The solvent-free extract having 80-95% brewing value constituents is pumped off into cans <PICT:0947596/C3/1> 29 which are hermitically sealed.  The spent hops from filter press 5 are treated in evaporator 35 for solvent recuperation, and treated for extraction of tannic principles with 3-10 times this amount of warm to boiling tap water which may be adjusted to pH 8-9 by addition of alkali.  The tannic principles extract may be mixed with the bitter principles extract by emulsification in the absence of air at pasteurization temperature to produce a highly concentrated hop extract.

Optical-projection apparatus.-Two shadows of an object are cast on to a screen by two light sources, and means are proxided whereby the left eye of a spectator sees one shadow only and the right eye sees the other shadow only, the effect produced being that of one shadow located between the screen and the spectator. As shown diagrammatically, light sources 11, 12, at a distance apart corresponding to the interpupillary distance, cast shadows of objects 13, 14 on to a screen 10. Red and green or other complementary colour filters 16, 17 are provided in the light beams, and filter holders in the form of spectacles having red and green filters 18, 19 respectively are worn by the spectators so as to cause the shadows to appear at the positions shown in broken lines. Movement of the objects causes apparent movement of the shadows without variation in their size. In a modification, the colour filters are dispensed with, and rotating shutters are provided to obstruct the light beams and the view of the spectator, such shutters being synchronouslv rotated so that the left eye sees only the shadow cast by one light source and the right eye sees only the shadow cast by the other light source.

IPC: H03H2/00
Filed: 1926-12-24
Abstract: 263,825. Lorenz Akt.-Ges., C. Dec. 24, 1925, [Convention date]. Frequency, changing. - Highfrequency oscillations, generated by frequency - multiplying devices such as saturated static transformers, are cleared from upper and lower harmonics by a combination of shunt acceptor circuits, which individually bypass the undesirable frequencies but collectively form a rejector circuit for the fundamental frequeny. The arrangement is applicable to reception as well as transmission. The resultant frequency in the tuned output circuit 23, 21, 25, Fig. 2, from a static transformer 16 is of the modulated form shown in Fig. 3, and can be analyzed into a fundamental frequency and upper and lower side bands. The latter components are respectively bypassed by two acceptor circuits 10, 11 and 12, 13, Fig. 1, shunted across the main oscillatory circuit and tuned to the side-band frequencies. To the fundamental frequency the shunt circuits will offer a capacitive reactance 14 and an inductive reactance 15, respectively, as shown in dotted lines. By a suitable proportioning of the respective capacity and inductance values, the resultant loop circuit 14, 15 can be adjusted to form a rejector circuit for the fundamental frequency, which accordingly alone passes to the aerial. Fig. 2 shows a cascade arrangement of static transformers 16, 17 fed from an alternating-current source 22, and shunted by tuned acceptor-rejector circuits 27 - - 34 and 10 - - 13 similar to that shown in Fig. 1.

Valve gear.-In timing-mechanism for fluidpressure engine valves, the necessary dismantling of parts in ramedying incorrect relative rotary adjustment of spiral, spur, &c. gearing 3, 20 is minimized by the use of a gear shaft 4 supported in two bearings 6, 5 on one or both sides of the wheel 3, one 6 of which bearings is removable and the other 5 is tiltable so that the wheels may be disengaged, rotated relatively, and reengaged. The invention is shown applied to the operation of a sleeve valve, in which the drive passes from the wheel 20 to the crank pin 40. The removable bearing 6 is maintained in position by a cover 7, which may be surrounded by a housing 13 serving to withdraw the bearing with the cover.
