Filed: 1948-02-02
Abstract: 646,224. Parachutes. FRIEDER, L. P. Feb. 2, 1948, No. 2984. Convention date, Feb. 11, 1947. [Class 4] A spring ring, capable of being bent and folded upon itself into a plurality of superposed coils without permanent deformation, is disposed around the rim of the canopy of a parachute to effect the opening thereof. The canopy 20 of a pilot parachute has at its rim a hem 28 which encloses a spring ring 30 comprising one or more rings of resilient material such as steel or rattan. The hem also encloses a cord 24 for the attachment of the shroud lines 22. To fold the parachute for stowage the spring ring is twisted into the form of a figure 8, the loops of which are then bent to coincide. The pilot parachute is then placed in the main parachute pack, being enclosed and restrained by the pack flaps until they are opened, whereupon the pilot parachute springs into the airstream and thus rapidly assumes its operative condition. The folding operation is illustrated. Specification 168,617, [Class 4], is referred to.

Abstract: 580,098. Rotary engines and pumps. ROGERS, G. Feb. 17, 1944, No. 3013. [Class 110 (ii)] An eccentric rotor 14, in a casing 13, carries straight or curved vanes 10, the ends of which are curved such that the radii of the ends in any plane of rotation are concentric about a common axis, and the contact at the vane ends with the casing 13 bore, or a hub 11, always lies on the vane radii. In Fig. 1 the vane end radii are struck from a centre 15 which is located at the intersection of lines passing through the vane corners. In a modification, the radii may be unequal, but still have a common centre. The circular surfaces swept by the vane ends may be conical as shown at 18 in Fig. 2, to allow for adjustment of the vanes. Each vane approaching the delivery port D has a radially inward pressure component which tends to relieve the bearing, pressure of the vane tip on the casing bore. Recesses 14, which may contain members 19, Fig. 3 are arranged behind the vanes.

Title: Improvements in or relating to circuit arrangements for selectors in telecommunications systems
IPC: H04Q3/00
Filed: 1957-01-28
Abstract: 801,800. Automatic exchange systems. SIEMENS & HALSKE A.G. Jan. 28, 1957 [Jan. 26, 1956], No. 3020/57. Class 40 (4). A single-motion selector GW which hunts in a group determined by the first received digit serves also to effect a discrimination dependent on the first two (or more) digits. In response to the first digit the selector moves to one of a series of rest positions HR1 ... HR10, say to position HR7. The groups of outlets Gr0 ... Gr9, however, are staggered in relation to the rest positions so that group Gr6 follows position HR7. The second digit stops the selector within this group and is also recorded in a mechanical impulse repeater in order to provide for the setting of a succeeding selector. The terminals of bank gwd are connected by marking wires to terminals of a discriminating switch AW, which, when dialling relay C (not shown). falls back, assumes a position corresponding to the first two digits. Relay Pz pulls up and the selector GW advances to the next rest position HR8. Relay Z now operates and the selector hunts for an idle outlet in group Gr7. It may be arranged that the selector takes more than two digits before reaching the group in which it hunts.

Patent GB-816993-A (GB)
Title: Preparation of bifunctional cyclohexanes
Filed: 1957-01-29
Abstract: Formyl-substituted cyclohexanes are prepared by introducing a formyl group into a cyclohexane which has a single functional group (as hereinafter defined) attached to the ring in a non-conjugated system, by reacting the cyclohexane with carbon monoxide and hydrogen at elevated pressures and temperatures in the range of 60 DEG  to 200 DEG  C. in the presence of a rhodium-containing catalyst which is soluble in the reaction mixture under the condition of the process. The term "functional group" is defined as a formyl, nitrile, aminomethyl, carboxyl, ester, alkylol or carboxamido group.  The cyclohexenes may also contain one or more alkyl substituents attached to the ring but leaving at least one active hydrogen atom on the olefinic carbon atoms.  Diluents such as hexane, heptane, cyclohexane or benzene may be admixed with the cyclohexane feed.  The rhodium catalysts specified are rhodium metal, rhodium carbonyls and rhodium compounds such as the dioxide, sesqui-oxide, halides, nitrate, sulphate, sulphite, stearate and oleate.  The rhodium catalysts may also be combined with known cobalt catalysts such as cobalt oleate. The cyclohexenes used as starting materials may be obtained by a Diels-Alder reaction between a conjugated diolefin, such as butadiene, isoprene, piperylene or a dimethylbutadiene, and an acrylic compound such as acrolein, methacrolein, acrylonitrile, methacrylonitrile and methyl methacrylate. Specified cyclohexenes are 3- or 4-formyl-cyclohexene, 2- or 3-methyl-4 - formyl - cyclohexene, 4 - methyl - 5 - formylcyclohexene, 3 : 5- or 3 : 6-dimethyl-4-formylcyclohexene, 2 : 3 - diethyl - 6 - methyl - 4 - formyl - cyclohexene, 3 - propyl - 5 - formyl - cyclohexene, 1 - methyl - 3 - formyl - cyclohexene, 4 - carboxy - cyclohexene, 3 - methyl - or 3 : 6 - dimethyl - 4 - carboxy - cyclohexene, 2 - methyl - 4 - cyanocyclohexene and 3 - methyl - 4 - carboxamido - cyclohexene.  In examples a mixture of D -3 : 4-tetrahydrobenzaldehyde and hexane is treated with carbon monoxide and hydrogen at elevated temperatures and pressures in the presence of rhodium sesquioxide and the product is distilled to give a dialdehyde (cyclohexanedial1 : (3 or 4)) and some hydroxyaldehyde. The carbonylation of 2-methyl-4-formyl-cyclohexene to give 2-methyl-cyclohexanedial-1 : 4 is specified.  Specification 801,734 is referred to.

Abstract: 425,930. Sampling coal &c. INTERNATIONAL COMBUSTION, Ltd., Aldwych House, Aldwych, and TAYLOR, G. E., 16, Normanby Road, Willesden, both in London. Jan. 30, 1934, No. 3134. [Class 58] A sampling device of the type in which a catchment pocket G moves at a constant speed through a stream of material descending from an inlet B controlled by a valve F is provided with means whereby the movement of the pocket may be arrested for a predetermined period with the pocket in inoperative position. The pocket is carried by a tubular member H through which the sample is discharged and which is driven through worm gearing from a motor R. The motor is controlled through two two-way switches N and S. The switch N is actuated to open one of its pairs of contacts and to close the other by an arm M carried by the shaft H, the effect being to break the circuit to the motor when the pocket has moved to the inoperative position. The switch S is clockwork-controlled and fitted with a change-speed gear between the clockwork mechanism and the cam controlling the pairs of contacts so that a desired and variable interval may elapse between the breaking of the one motor circuit by the arm M and the closing of the alternative circuit. through the other pair of contacts due to the action of the clockwork. The side K of the catchment pocket G may be adjustable to vary the quantity of material taken for sample.

Title: Improvements in or relating to devices for driving workpieces on machine tools such as automatic lathes
IPC: B23B5/24
Filed: 1958-01-30
Abstract: 882,822. Automatic lathes; work drivers. REGIE NATIONALE DES USINES RENAULT. Jan. 30, 1958 [Feb. 18, 1957], No.3205/58. Class 83 (3). A work-driver for an automatic lathe to which a succession of workpieces such as engine pistons are fed in predetermined angular position, comprises a spindle adapted to support one end of the work and a coaxial drive shaft which can be connected to rotate the spindle and which is automatically brought to a selected angular position to receive the work. The lathe spindle 5, Fig. 1, is provided with a spigot on its end between which and a tail-centre 6 the piston 4 is supported. A work-driver 3, Fig. 5, engages the gudgeon-pin bosses 4<SP>1</SP> inside the piston to give it positive rotation. The driver is carried on the end of an axially movable shaft 2, Fig. 1, arranged along the spindle-axis, which has keyed thereto a tapered collar 9 with splines on the outside to engage splines on the inside of the spindle when the shaft 2 is in driving position. The shaft is moved forward when the tail-centre 6 has been retracted, to remove the work, the splined drive to the collar 9 being thus disengaged. A compression spring 11 is provided between a bush 10 in the spindle and the end of the shaft 2 so that it tends to return to the " drive-engaged " position. A flange 14 with " locating " holes 15 is keyed to the end of shaft 2 and lies adjacent to a driving member 46 secured to a sleeve 49, Fig. 2, rotatable about a shaft 17. The outside of the sleeve is provided with gear teeth which engage a rack 53 moved by pneumatic piston-and-cylinder mechanism in timed relation with the other parts of the automatic lathe. The driving member carries spring plungers 47 which engage the holes 15 in the flange 14 when shaft 17 is moved to the right (direction F) and flange 14 and shaft 2 are thus rotated to position the driver 3 at the start of an operation so that the driver enters the piston in the desired position. Shaft 17 has a splined portion 38 which engages a splined sleeve 40 fixed to the frame of the machine and thus prevents rotation of the shaft. A further extension 17<SP>1</SP> of shaft 17 is screw-threaded and engages a rotatable nut member 33 formed on the outside as a worm-wheel to engage a worm 26. The latter is rotated by an electric motor which is switched in to move the spindle 17 and thus, by contact with the flange 14 on shaft 2, to move this shaft forwardly against the pressure of the spring 11. A stem 41, Fig. 2, is secured to the rear end of spindle 17 and this carries a cam-piece 42 for operating limit switches 43, 44, controlling rotation of the motor-drive to the worm 26.
