Abstract: 426,916. Casement windows; sliding- doors. BIEL, H., 3, Victoriastrasse, Itzehoe, Germany. Sept. 11, 1934, No. 26113. [Class 20 (iii)] A window comprising one or more horizontally sliding and pivoting sashes which lie in the same plane as adjacent hinged or other sashes when closed has top guides 8, 9, 10, for the hangers of the supporting rollers 25, 28, Figs. 2, 7, 8, the branch 9 permitting the rear meeting edge to be swung inwardly and slidden along the guide 8, the hanger stem finally engaging a socketted plate 12. The sash then is adapted to pivot and the forward hanger stem passes through the branch guide 10. The movements at the bottom of the sash are controlled by a fixed guide 22 and a pin 35 on the sash for the swinging movement and a fixed stop 17 and a slot 31 in the sash for the sliding movement. The pin 35 enters a socket 21 having a flared opening 20, Fig. 14 for the pivoting movement. During pivoting the sash is retained by an eccentric pin which rotates with the stem 25 in the quadrant 13, Fig. 2 at the upper end and by an elongated part of the pin 35 in the opening 21 at the lower end. Wear plates 11, Fig. 2 and 17 are provided to protect the guide 8 at the junctions with the branches 9, 10. Upper and lower cams 14, 16, are provided to engage a bracket and a curved edge of the grooved member 31 respectively to effect a tight closure. In the neighbourhood of the branches 9, 10 guide strips are provided to engage grooves 40 in the supporting rollers. The branch guide 10 may be closed at the end the guide roller being then mounted on a spring-controlled stem and depressed out of the guide before pivoting the sash.

Title: Catalyst for gas phase oxidation reactions and processes effected therewith
IPC: B01J23/42
Filed: 1955-09-13
Abstract: A catalytic oxidation in the gas phase, e.g. for the production of hydrogen cyanide or nitric oxide, is carried out by passing a suitable gaseous mixture downwards first through one or more platinum or platinum alloy gauges and then through a layer of granular refractory material coated with platinum or a platinum alloy, the gauge and layer of coated granular material being in contact and gauge and coating each containing at least 50 per cent platinum.  The gauge and coating may contain 80-90 per cent platinum and 10-20 per cent rhodium.  The refractory material may be beryllium aluminium silicate, silica, porcelain or alumina of 6-10 mesh, and may be used in a layer 0.75-1.5 in. thick.  The gauze may be activated for subsequent use by interposing between a previously activated gauze and already used coated granular material, and carrying out reaction for 3-30 hours.  Hydrogen cyanide may be produced from ammonia, natural gas and air in the volume ratio of 1 : 2 : 10.

Title: Improvements in warp stop mechanism for looms
IPC: D03D51/28
Filed: 1926-10-23
Abstract: 282,524. Corlaas, T. C. Oct. 23, 1926. Stop-motions, warp.-The healds 3 are used as detector members, their upper ends enclosing a metal cross bar 4 grooved to receive a metal bar 5, which is insulated from the bar 4 by sheet rubber &c. The bar 5 is electrically connected to an insulated spring 9, which, when the healds are lowered, but not otherwise, contacts with an insulated contact rod 10, electrically connected through a battery 11, a casing 7 and a wire 6 to the bar 4. When a warp thread breaks or slackens unduly, the electric circuit is completed, through the corresponding heald 3 as shown in Fig. 7 and an electromagnet 12 in the casing 7 is energized, whereby a spring-controlled hooked lever 13 is attracted, and a lever 15 is liberated. The casing 7 is carried by a lateral projection 7<a> on the starting handle 16, and the lever 15 when released from the lever 13 falls into a horizontal position in the path of a member 17 on the lay, whereby the starting handle 16 is actuated to stop the loom. The electrical connections include an insulated wire connected to a terminal 7<b> of the casing, whence the current passes through the coil of the electromagnet, through a wire 161, thence through a spring 14, and through the levers 13, 15 to the casing 7, so that as soon as the circuit is completed and the lever 13 is attracted, the circuit is at once broken owing to the release and fall of the lever 15. Thus the electric circuit is at no time more than momentarily completed. The Provisional Specification describes an arrangement wherein the breaking of a warp thread energizes a solenoid, which releases a spring-controlled bunter finger pivoted on the weft fork hammer, so that this actuates a pivoted bunter on the weft fork arm and stops the loom. The releasing of the bunter finger is arranged to cut out the current.

In a swash-plate pump or motor comprising a rotary cylinder block 40 engaging a ported valve face 17 and pistons 47 engaging a tiltable swashplate 55 through shoes 49, independent springs 93 and 100 bias the block against the valve face and the piston shoes against the swash-plate. Spring 93 acts between a seat 89 on the block and a seat 88 on the drive-shaft 20, and spring 100 acts between a seat 97 in the drive-shaft and a piston member 102 coupled to the piston shoes 49 by pins 106, part-spherical member 105 and retainer plate 115. Spring reaction forces are transmitted to the casing 12 through roller bearings 24, 29 axially and radially locating the drive-shaft. The swash-plate is adjusted by fluid-pressure acting on a piston 69, a constant biasing pressure being applied to a piston 76. Alternatively, the adjusting pressure may be applied to both pistons 69 and 76. In the embodiments of Figs. 2 and 5 (not shown), alternative coupling arrangements are used between spring 100 and the piston slippers, and the drive-shaft carries a gear-wheel (216).

Abstract: 766,927. Linear polyamides. CALIFORNIA RESEARCH CORPORATION. Sept. 22,1954 [Sept. 29, 1953], No. 27462/54. Drawings to Specification. Class 2 (5). Linear polyamides are formed from adipic; suberic or sebacic acid and a mixture of meta- and para-xylylene diamines containing 5-90 per cent by weight of the para-isomer. The xylylene diamines may be prepared from commercial mixtures of xylenes in which the para isomer commonly constitutes 25-30 per cent of the mixed meta-para-isomers. In Example I an aqueous solution of a salt was prepared from adipic acid mixed m- and p-xylylene diamines (90: 10). Water was removed by heating in a current of nitrogen. Polymerization commenced at 190‹ C. and a low polymer was formed. Continuous heating at 275‹ C. and low pressure produced a crystalline polymer melting at 245 C. Example II is similar. A number of polymers from adipic or sebacic acid and mixed diamines with varying proportions of the two isomers are also described and compared with polymers prepared from adipic or sebacic acid with pure meta- or para-xylylene diamine, and with polymers from meta-xylylene diamine and mixtures of adipic and terephthalic acid. The products of the invention are characterized by high melting points and heat distortion points and suitability for melt spinning or extrusion.
