Abstract: 437,009. Refrigerating. FARAGO, J., 5, Ferenc Jozsef-ter, Budapest. March 8, 1935, No. 7222. [Class 29] [See also Group XXVI] Compression machines.-A flexible-tube compressor is employed in machines for domestic &c. use, and may comprise a endless rubber hose 1, Fig. 1, mounted on the rim of a rotary condenser member 3 of lenticular form and provided with cooling fins 9, 10, the hose being compressed and rotated by a roller 2 carried on the shaft of a driving motor 15. The gas compressed in one part of the hose is delivered through a valved radial pipe 12 into the interior of the condenser and the condensate flows down a pipe 13 to a finned evaporator 7 rotating with the condenser. The evaporated gas returns through the common shaft and by a radial pipe 6 to the hose chamber. In a modification the hose is mounted on a beltdriven pulley 22, Fig. 3, which carries a coiled condenser 25, the pressure roller rotating on a fixed shaft. The hose is preferably of the section shown in Fig. 5, the walls being thicker in the line of pressure, and preferably the compression chamber tapers circumferentially in the direction of gas flow. Alternatively the internal section of the hose may be circular and the external section non-circular. The hose may be enclosed in a gas tight casing, and may be mounted on a stationary member, the pressure roller travelling around it.

Title: Apparatus for gas analysis
IPC: G01N27/12
Filed: 1975-02-20
Abstract: 1495584 Burner control K J EHLEN 20 Feb 1975 [21 Feb 1974] 7233/75 Heading F4T [Also in Division G1] A semi-conductor gas sensor has its output applied to a differential amplifier. The sensor 1 may be used to monitor the combustion operations of an oil burner and is disposed in a measuring chamber to which the gas from the burner is applied to monitor the CO content of the gas. At the start of the monitoring operation switch 15 is closed by a relay circuit, Fig. 2 (not shown) at the same time as the gas supply to the measuring chamber is initiated so that not only A.C. heating current is supplied via secondary 9 to electrode 2 of the sensor but D.C. from full-wave rectifier 12 is applied across the electrodes 2, 3, electrode 3 being connected to the non-inverting input 22 of differential amplifier 20 to monitor the resistance of the semiconductor between 2, 3. The inverting input 21 is connected to potentiometer 17, 18, 19 which supplies a "set" value thereto. During the starting period of the burner the sensitivity of the amplifier 20 is reduced by connecting resistor 29 across 19 so that no warning signal can be given. After the starting period determined by a timing circuit a further relay, Fig. 2, is energized to open switch 30 and increase the sensitivity. If then the amount of CO present is such that the potential at 22 is greater than the "set" value then the output at 44 is such as to energize relay 31 to actuate a visible or acoustic alarm or shut off the burner. The amplifier output also energizes or de-energizes relay 34 to switch contact 36 from one position to another to cause LED 37 to emit red or green light. Relay 31 may be replaced by a triac arrangement, Fig. 5 (not shown) in which case the amplifier 20 is provided with a feedback circuit. The timing circuit may include a counter, Fig. 4 (not shown) so that measurements are taken after a predetermined number of firing operations.

E., 11, Atlingworth Street, and PATTERSON, S., 5, New Steine, both in Brighton, all in Sussex. March 8, 1935, No. 7301. Addition to 413,871. [Class 65 (ii)] The invention described in the parent Specification is modified by mounting the pivot pins and their operating and locking means on the fixed frame and providing the sockets in or on the door or window. In the arrangement shown in edge view, a window carries at each side a pair of sockets b for engagement by L-shaped pins d working in guides i on the frame and carried by sliding bars f which have at their adjacent ends rack teeth for operation by a pinion on the spindle of a handle m. The upper ends of the upper bars f have V-notches for engagement by the ends of a locking bar (not shown) sliding across the top of the frame, this bar being of such length that it always engages one or other of the notches ; when the pins at one side of the window are withdrawn from their sockets, therefore, those at the other side are held in their engaged position. In order to prevent projection of the withdrawn pins while the window is open, which would allow retraction of the other pins and complete removal of the window, the locking bar is formed at its middle part with two notches which are selectively engaged by a lug on a spring bolt s so that the locking bar can only be moved when the bolt s is pressed back by a lug u on the window when the latter is in the closed position.

Title: Improvements in and connected with electric supply systems for lighting, heating andventilating railway carriages and other vehicles
IPC: H02J7/18
Filed: 1919-03-24
Abstract: 145,145. Rohman, H. D. March 24, 1919. Lighting and heating systems; regulation, automatic systems and apparatus for; systems of charging and discharging galvanic batteries.-In an electric supply system for railway carriages and other vehicles, of the type provided with a dynamo, battery, and an electro-magnetic solenoid cut-in switch, the latter, after closing, progressively lifts a series of switch brushes to disconnect parallel-connected resistances in order to suit the dynamo supply to the conditions obtaining in the consuming circuit. In the system shown in Fig. 1, the cut-in switch C, after closing to connect the dynamo in parallel with the battery B, which is at that time supplying the lamps through a contact 17 controlled by the cut-in switch, opens in succession contacts 17, 2b, 3b, and 4b, disconnecting thereby, in succession, a short-circuit and resistances 2<c>, 3<c>, and 4<c>, which are all connected in parallel with a high positive temperature coefficient resistance r in the lamp circuit. Each step is controlled by the circuit conditions, through a solenoid wound with a shunt coil 10 and a servo coil 11, so as to obtain a gradual adjustment of resistance until the dynamo is giving maximum output. Means may be combined with the switch, operating for example in sequence with the steps of resistance regulation, to make an additional connexion of the lamp circuit to the battery at an intermediate point of the latter, e.g. the fifth cell of a 23-cell Edison battery. Such an arrangement is shown in Fig. 6, in which the contact 17 has a projection engaged by an upper switch brush when the maximum resistance has been inserted into the lamp circuit. To ensure uniform charging throughout the battery when so used, a resistance M, calibrated to pass a small current only, is placed in parallel with 18 cells of the battery when the load is removed. The stop charge device H and the reducer mechanism G shown in this Figure are described in Specification 145,120, which is referred to. The cut-in switch may be constructed as shown in Figs. 2 and 4. A head H carried by the solenoid wire has a number of projections 1<a> of different heights, each of which may be adjustable. These projections in turn abut against and lift switch brushes 1 which normally engage fixed contacts. A yoke H' carried by the head H ensures the replacement of all the switch brushes when the cut-in switch is opened.

Filed: 1944-04-21
Abstract: 579,475. Filtering gases. HEATHER, F. April 21, 1944, No. 7428. [Class 8 (ii)] An air or gas filter comprises fibrous filtering material confined to form a hollow body through a part of which gas first flows from the exterior to the hollow interior and then through another part of the body into an exterior manifold having one or more outlets for the filtered gas. The body comprises a tubular element formed of a spring 2a having spaced coils to hold rings of wire brush material 3. The interior 4 is closed by a cap 5 held by a nut and bolt 18, 17 which also holds the body in the surrounding manifold 8 for supplying filtered air to say an I.C. engine. In a modification the body comprises inner and outer perforated tubes to which are spot welded radial imperforate partitions forming compartments to hold lengths of brush material. In a further modification two filter bodies are secured end to end one or either side of a closure plate for the said ends with the adjacent halves of each body within the manifold. The greater portion of the body or bodies is enclosed by the manifold to induce a lower velocity of the outlet air relative to that of the inlet air resulting in dust deposition in the space 4. Cotton, asbestos, and other fibres may be used and cleaned by immersion in paraffin, hot soda or soapy water. Specifications 376,436, 537,017, and 542,179, [Group XXVII], are referred to.

Filed: 1946-03-11
Abstract: 609,290. Tamper-proof closures for non-refillable &c. bottles &c. FAIRWEATHER, H. G. C. (Inter-Seal Corporation). March 11, 1946. No. 7556. [Classes 125 (i) and 125 (iii)] A closure to prevent illicit opening of bottles and like containers comprises an outer cap portion 14 provided with a skirt 19 which has an internal thread 20 for engagement with a corresponding thread 11 upon the bottle neck and an inner member 15 containing a valve arrangement V, W, a cork 18 being provided in the pouring outlet 17 of the closure. The inner member 15 has a flange 26 upon whose upper and lower surfaces respectively are formed sets of oppositely inclined ratchet-like teeth 27 and 28, the upper set 27 cooperating with a similar set 22 on the member 14, and the lower and smaller set 28 contacting a gasket 16 housed in the recess 21, 21<1> of member 14. When applying the closure, member 15 is caused to rotate with the part 14 by the engagement of teeth 22 and 27, teeth 28 sliding over the gasket until sufficient pressure is exerted by the member 14 upon the flange 26. On counterrotation of the portion 14, inclined surfaces 22' of the teeth 22 slide along similar surfaces 27' on teeth 27, and by virtue of their greater inclination than the pitch angle of the bottle thread, and the fact that member 15 is prevented from rotation by teeth 28 biting upon the gasket, an upward pressure is exerted until ultimately breakage of the skirt 19 occurs. In a modification, Fig. 7, which has no valve arrangement, the outer member 42 is weakened by opposing grooves 50, 51, in the crown, counter rotation in this case causing rupture along the weakened portion 52. In either case the gasket may be of material having a high coefficient of friction with the container, or mechanical means may be employed to prevent its rotation, such as a series of projections engaging similar depressions in the neck of the container.
