Abstract: 714,386. Gas burner igniters. HORSTMANN GEAR CO., Ltd. Aug. 28, 1953 [July 23, 1952]. No. 18640/52. Class 75 (3) In an electric battery operated portable hand torch lighter for a gas burner the passage of gas is controlled by manually operated means which simultaneously operate a switch 11, 18 in the igniter filament circuit and release a gravity valve member 20, normally held in the closed position, to permit it to move to the open position. The gravity valve member 20 is housed in a body 10 urged to the forward position by a spring 16 to hold the valve 20 comprising one or more balls between the end of the tube 9 and the valve seat 21. The body 10 moved by a trigger 23 is rearwardly slidably moved along the tube 9 to release the bulbs so that when the nozzle 4 is pointed downwards the balls of the valve 20 will move so as to bear against the end of the tube 9 to allow gas to pass through slots 36 in the end of the tube 9 to the torch nozzle 12 and when the nozzle 4 is pointed upwards the balls will roll against the valve seat 21 to cut off the gas supply. The filament 6 is carried by a pair of conductive arms 8 mounted in an insulating block 7 carried by a lever 5 and the circuit to the element 6 is through the contacts 11, 18, the valve body 10, tube 9 and one arm 8 and returns through the lighter casing. The nozzle 4 is detachably mounted on the casing end. In an alternative arrangement, Fig. 2, the valve body 10 is moved by a bell-crank lever 31, the spring 16 is replaced by a resilient member 35 of rubber or the like, the gravity valve is formed by a member 29 of polygonal cross-section, and the casing 1 is of an insulating material the return from the filament 6 being through a conductor 26 having a spatulated end 27 which bears against the side of the battery 3. Specification 477,498 is referred to.

Title: Detecting metabolic activity
IPC: C12M1/34
Filed: 1978-06-23
Abstract: An apparatus and method for detecting metabolic activity in a medium which includes an electrical circuit suitable for passing electrical current through a medium which contains a suspected metabolic agent. The circuit includes means for generating a reference voltage. When metabolic activity occurs in the medium the voltage drop thereacross changes. To balance the changing voltage developed across the medium with the generated reference voltage, an adjustment of current has to be performed. By monitoring such adjustments, made electrically and automatically, there is a correlation made between those adjustments and the metabolic activity in the medium. Use of this apparatus and method allows large quantities of sample media to be tested for detection of metabolic activity rapidly, accurately and reliably.

Title: Austenitic manganese steel for railway frogs
IPC: C22C38/04
Filed: 1978-10-20
Abstract: The steel consists, by weight, of 0.75 to 0.9% of carbon, not more than 1% of silicon, 12.5 to 15% of manganese and 1.0 to 1.8% of molybdenum, the balance consisting of iron and unavoidable impurities. The steel, unlike conventional austenitic manganese steel for railway frogs, is not susceptible to carbide precipitation on heating. Frogs can therefore be made from the steel by casting and the frogs can be welded, both without the need for hyperquenching.

Patent GB-2020749-A (GB)
Title: Positive-displacement pump
IPC: F04C14/02
Filed: 1979-05-11
Abstract: A two-stage pump for maintaining a constant delivery rate independently of viscosity fluctuations has a first stage e.g. a gear pump 2, which supplies fluid e.g. fuel oil, to an intermediate chamber 8. A second stage e.g. a gear pump 4, delivers a smaller quantity of fluid from the chamber 8 to a delivery line 11. The line 11 and a return line 9 from the chamber 8 are connected to opposite sides 14, 15 of a diaphragm 13. The fluid flows through throttling orifices 21, 22 regulated by the diaphragm. The diaphragm regulates the pressure differential in the lines 9, 11 to zero. Thus there is a zero pressure-gradient at the second stage, so that the viscosity changes have no effect on the delivery rate. The line 9 may contain a pressure-relief valve 17; and the second stage may be driven through reduction gears 3. <IMAGE>

Patent GB-2032054-A (GB)
Title: Resilient mounting
IPC: F16F1/387
Filed: 1979-10-02
Abstract: A resilient mounting comprising a tubular bush (3) of elastomeric material acting between and bonded to confronting surfaces (10, 12) of rigid inner and outer members (1, 2). The bush (3) is formed with a cut-out (13) on that side which would otherwise be subjected to tensile forces in use and the relative spacing between the members (1, 2) is subsequently reduced by either expanding the inner member 2 or contracting the outer member 1 to close at least part of the cut-out (13) and selectively pre-load the elastomeric material in the unloaded condition of the mounting. The reduction in spacing can be controlled to give the required pre-loading and may be sufficient to ensure that the elastomeric material is always under compression in use thereby avoiding the occurrence of tensile forces with consequent improved fatigue life. Preferably the mounting incorporates resilient limit stops (15, 16) to control relative movement between the members (1, 2) both in the axial direction of the bush (3) and vertically under a working load. <IMAGE>

The space below the recuperator unit and around the producer is freely accessible to the operating staff except for a waste gases flue 13 disposed below the recuperator. As shown in dotted lines in Fig. 1, two settings can be arranged contiguously, in which case a connection (not shown) is provided between the adjacent producers, so that one producer can serve both banks of coking chambers. The invention may be applied to other forms of coking chambers.

Title: Analyzing the amplitude spectrum of a speech signal by regularly selecting time segments thereof
IPC: G10L25/90
Filed: 1979-12-11
Abstract: Method of and arrangement for the determination of the pitch of speech signals in a system of speech analysis, wherein sequences of significant peak positions of the amplitude spectrum of a speech signal are derived (13) from time segments of the speech signal by means of a discrete Fourier transform (12). In order to reduce the influence of noise signals and noise components, respectively, in the amplitude spectrum the significant peak positions are compared with different masks (15), which have apertures at harmonic distances of the associated fundamental tone. The mask which matches the sequence of significant peak positions best is selected (20). A probable value for the pitch is now computed with the harmonic numbers now known of the significant peak positions which are located in apertures of the selected mask. The mean square error between these significant peak positions and the corresponding harmonics of the finished tone can be used as a criterion (21).
