Abstract: 442,251. Nonconducting coverings for sound. OELSNER & CO., W., 5, Rosenborggade, Copenhagen. Dec. 5, 1934, Nos. 34951 and 34952. Convention date, Dec. 5, 1933 and March 7, 1934. [Class 64 (ii)] [See also Groups XXXVIII and X] The walls of a broadcasting &c. studio have their upper parts covered with sound-absorbing material and the lower parts with sound - reflecting material. The outer walls 3 of brickwork or concrete contain I-beams 1, the surfaces of which are covered with soundinsulating material such as jute, asbestos, cork or lead, attached by means of a bituminous coating. The inner face of the walls and roof has a coating 4 of sound-absorbing material such as asbestos wool, straw, peat, &c., which may be formed in slabs preferably having the material disposed between layers of expanded metal coated with plastic bituminous material. In front of the lower parts of the walls are disposed sectional panels 5 of rough-surfaced sound-reflecting material such as stone or porcelain inserted in frames 6 of metal &c. Supported above the panels 5 on brackets 7 are further panels 8 of soundabsorbing material such as asbestos wool &c., mounted on frames 11 and covered with silk &c. fabric or metal wires 9. The beams 1 carry other I-beams 2 supporting a ceiling consisting of two or more layers of metal netting 13, Fig. 4, filled with plastic material 14 with covering and separating layers 15 of woven fabric, the lower layer being preferably coated with a layer of a fluorate to give reflecting power. The upper panelling 8. may be separated from the wall so as to provide behind it accommodation for blinds which may be let down as required to modify the reflecting quality of the lower panels. The Specification as open to inspection under Sect. 91 states also that the space behind the upper panelling may accommodate alternative sound-reflecting panelling. This subject-matter does not appear in the Specification as accepted.

Title: Control of flow of pressure medium
IPC: F16K21/04
Filed: 1975-08-22
Abstract: 1501448 Valves SIEMENS AG 22 Aug 1975 [12 Sept 1974] 35057/75 Heading F2V In dental equipment a valve 21 tilts under gravity to permit fluid flow when a rigid arm 9 pivots about axis 7 on moving a hand-piece 10 from a rest position on a cradle 12 to an operative position. The valve is pivotally mounted about axis 22 on a mount 21 which is fixed to a tubular support 6 on a pillar 4 that rotates about a vertical axis 14. The arm 9 is connected to and supports the supply pipe 11 to the handpiece and normally abuts the valve to hold it in closed position. The valve member is a loose ball 27 (or piston) which rolls from a position closing a seat 29 between an inlet 31 and an outlet 30 to one abutting a wall 32 when the valve pivots. A pair of valves may be mounted in a common frame, which is pivotally mounted to simultaneously control flow to two handpieces. Flow can thus only take place to a handpiece when it is in an operative position.

Title: Improvements in and relating to liquid fuel burners
IPC: F23D11/00
Filed: 1936-06-24
Abstract: 479,019. Liquid - fuel burners. KNUPFFER, M. June 24, 1936, No. 35123/37. Divided out of 477,296. [Classes 75 (i) and 75 (iii)] The draught tube 4 of a liquid-fuel burner is formed with a slot 16 around the mounting 6 for the fuel atomizing nozzle 7 so that, after the removal of a segment 19 currying the ignition electrodes 20, 21, the tube may be slid back over the fan housing 8a to allow of access to the fuel nozzle 7 and fan blades without breaking any oil supply connections. The mounting 6 may consist of a massive metallic conductor in heat conducting relationship with a fuel preheating chamber 5 as described in Specification 477,296. Alternatively, an immersion heater may be fitted in the fuel nozzle. The draught tube is formed with flanges engaging guides 37 on the housing 8a and with an opening 12 registering with the tangential mouth 13 of the housing. The fan, fuel pump, and driving motor are preferably arranged on a common axis at right-angles to the axis of the draught tube. A pivoted damper 11, operated by the air or fuel pressure, closes the mouth 13 when the fan is idle. A multivaned swirler 17 is provided at the outlet of the draught tube. A small tube section 18 permanently secured to the front of the mounting 6 fills the slot 16 and preserves continuity of the swirler and tube 4 when the tube is in position. A cut-off valve 10 in the fuel nozzle is prevented from opening under the influence of a light spring 23 until the fuel pressure acting on a diaphragm 14 overcomes the pressure of a spring 26 and withdraws a spindle 27 arranged in a fuel tube 3 secured to the mounting 6. The segment 19 is provided with a window for viewing the spark gap and nozzle.

Abstract: 1,235,500. Transistor saw-tooth circuits. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 23 July, 1968 [25 July, 1967; 21 Aug., 1967; 22 Aug., 1967; 21 Sept., 1967], No. 35128/68. Heading H3T. [Also in Division H2] An E.H.T. generator for a TV receiver comprises a ceramic transformer 30 (Fig. 1), a horizontal deflection output circuit 10 for generating a pulse voltage and coupled to the transformer input to produce E.H.T. at its output electrode 34, a deflection yoke 20 including a core 25, on which is wound a choke coil 26, horizontal deflection coils 21, 22, vertical deflection coils 23. The choke coil is connected to a D.C. source 60 and conducts power to the horizontal deflection circuit 10 and is wound to produce a magnetic field perpendicular to the fields induced by the vertical and horizontal coils respectively. Pulse voltage is applied via a transformer 11 to switch a transistor T12 on, so that current flows in coils 21, 22. When T12 is switched off energy stored in the coils discharges so that an oscillation develops and a damper diode 13 is cut-off. After a half-cycle of oscillation D13 is forward biased and the oscillation is damped. Thus a flyback pulse having a width equal to half a cycle of oscillation is produced and drives the piezo-electric transformer. In an alternative embodiment (Fig. 3, not shown) the choke 26 has a loosely coupled secondary coil driving the ceramic transformer, and provides a clipped pulse output more closely approaching the ideal drive pulse shape. A lower voltage for the tube grids is provided between electrodes 33 and 32 of the transformer.

Title: Apparatus and method for winding threads

Filed: 1970-07-22
Abstract: 1317933 Traversing ZINSER-TEXTILMASCHINEN GmbH 22 July 1970 [22 July 1969] 35632/70 Heading D1J Package-end build-up is prevented in a winding machine where the yarn is traversed between rotating cam plates 16..19, whilst guided by slots 60 in a guide bar 57 (Fig. 6), by periodically radially displacing the cam plates to change the width of traverse. Two cam plates are radially slidably mounted on each of two spindles 43, and carry projections 37 (Fig. 4) engaging with an internally conical ring 40, axially slidable on the spindle by rollers 43, push-rods 45 (Fig. 2), rocker arms 47 and a cam 50 (Fig. 1, not shown). The rotation of the spindles is geared by sprockets 20, 21 and a chain to that of a package-driving roller 27 in an integer ratio. The roller 27 has chevron-shaped grooves 33 which during normal operation, when the cam plates are in their radially outermost positions, catch the thread as it nears its reversal points, and ensures substantially helical winding in these regions. An operation of the cam to retract the cam plates 16..19, the traverse length shortens beyond a point where the grooves 33 no longer catch the thread, which is therefore laid in a curve at the reversal regions until the cam plates ar extended once more. A pair of cam plates on one spindle may serve two winding stations, the spindle being located centrally between them.
