Title: Improvements in, or relating to, commercial vehicles
Inventor: MAXWELL CHARLES BARRY
IPC: B60P1/64
Filed: 1968-03-14
Abstract: 1,204,064. Container traffic. ABELSON MOTORS Ltd. 16 June, 1969 [14 March, 1968], No. 12500/68. Heading B8Q. A road vehicle chassis, Fig. 1, has a pair of bellows 9, located above the rear axle, which raise a detachable stillage, Fig. 2, so that its legs 34 may be folded and unfolded during loading and unloading operations. The legs are as described in Specification 1,145,181. Safety means are provided on the chassis to prevent its withdrawal before the stillage legs have been moved to their operative position. The chassis is backed under the stillage until rollers 36 are vertically above a transverse member 38, and the bellows are inflated, through a nipple 17 and conduits 18, 22, thus raising a pivoted carriage 12, provided with rollers 16 which engage the stillage. The front 15 of the carriage 12 operates a valve to stop inflation of the bellows. With the front of the stillage raised by the inflated bellows the front legs are folded to inoperative position and the bellows are deflated. The front of the stillage is now supported by the rollers 36, Fig. 2, which run on beams 8 as the chassis is reversed again. Reversing continues until the rollers 36 engage noses 7 at which point the bellows are inflated again and the rear legs are folded. Spring-loaded plungers 39, Fig. 1, lock the stillage in position. When the chassis is being withdrawn from the stillage a safety bracket 31 abuts a bracket 37 at the front of the stillage thereby ensuring that the chassis cannot be withdrawn until the front legs are in their operative positions. Alternatively, the top 8 of the guides 4, 5, Fig. 1, may be formed with depressions which arrest the rollers 36 as the chassis is withdrawn but not as it is inserted. Fig. 4 shows a further safety device in which the stillage is engaged by a spring-loaded tongue 45 normally held in an inoperative position by a latch 47. The latter is automatically withdrawn by cams 53, 55 and links 52, 56, 57, 58 when the stillage is being set down but is held inoperative when the stillage is being loaded on to the chassis.

Abstract: 377,314. Air compressors. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. April 28, 1931, No. 12513. [Class 8 (i).] A multiple-cylinder compressor is provided with sleeve valves controlling the inlet and outlet ports and with unloading means whereby the cylinders are put into communication. The compressor pistons F work on cranks at 180‹ so that the sum of the volumes of the compression spaces is substantially constant. The cylinders have sleeve valves E with admission ports E<2> and delivery ports E<3> which during the oscillating and reciprocating motion of the sleeves communicate respectively with inlet ports C communicating with a supply passage C<1> and outlet ports D<1> arranged between the cylinder heads D and the cylinder liners B<1> and communicating with outlet chambers H which communicate through a passage H<1> with the delivery pipe H<3> through a spring-pressed valve H<4> provided with a dashpot. The sleeve valves are driven through toothed gearing from half-speed shafts. The cylinder heads are provided with unloading valve D3 which when open put the cylinders into communication and the delivery ceases. The valve H<4>, which normally remains open, closes and stops the backflow of air. The valves D3 are raised by levers K operated by a piston L mounted in a cylinder L<1> arranged in an oil chamber M, Fig. 3. The piston is pressed up by a spring L<3>, and the cylinder is open to the oil. The chamber M is put under atmospheric pressure or delivery pressure by a piston valve N<2> loaded by a weight N<6> and subject to the delivery pressure through a pipe N<1>.

Abstract: 1,028,610. Can carriers. FRITZ BUSCH DRUCKEREIGESELLSCHAFT m.b.H. March 25, 1965 [April 1, 1964; Dec. 24, 1964], No. 12711/65. Heading B8C. A holder for flanged containers (Fig. 8) is made from a single cardboard blank and has the longitudinal edge portions 27 and 28 folded inwardly and adhesively secured to the longitudinal sides 22 and 23. Apertures 29 are provided in the longitudinal sides through which the beaded rim or cover of the container may project. The apertures may be large cut-out portions 29 as shown, and may be tapered towards the central panel 21 of the holder, so as to more closely conform to the shape of the container cover. Alternatively they may be just small slots which are made when the side walls 22, 23 are folded downwardly leaving the tabs 31 and 32 level with the central plane 21. The lower edge 34 of the aperture may be provided with cuts or recesses 36 which enable the bottom portion of the wall 22 to fit snugly under the rim or cover. The longitudinal edges of the folded in portions 27 and 28 may coincide with the edges 34 of the apertures, or they may extend slightly above these edges, or, as shown in the Figure, they may extend under the central panel 21. In this latter case the portion of the walls 27, 28 underneath the central panel 21 is not secured thereto and apertures are also provided in the walls 27 and 28 so that the tabs 31 are of double thickness. The holder is assembled about the container either by machine or by hand, by placing the flat blanks on top of the containers and forcing down the wall portions 22 and 23 so that the rims or covers project through the apertures 29.
Patent GB-421316-A (GB)
Title: Improvements in or relating to looms with stationary shuttle boxes and movable slays
IPC: D03D49/60
Filed: 1934-04-27
Abstract: 421,316. Looms having shuttle-boxes which do not move with the lay. GRAF, J., Bahnhofstrasse, Uzwil, Switzerland. April 27, 1934, No. 12732. Convention date, April 28, 1933. [Classes 142 (i) and 142 (iii)] A loom with stationary shuttle-boxes and a movable lay is provided with at least one clutching means, of mechanical, electrical, hydraulic or pneumatic type, for detachably connecting the lay or the lay support to its immediate driving members, the latter being constantly operated by cranks, cams or grooved discs on the crank shaft. The clutch may be controlled by warp protectors, weft feeler or stop motion mechanism or cop guards and, in the event of disturbance in the shuttle course, a shuttle feeler disconnects the clutch and effects stoppage of the loom. Beat-up motions; lays; shuttle-boxes.- In the construction shown in Figs. 1 and 2, the lay 4 is provided with pivoted pawls such as 7 for engagement with pivoted swing levers 3 which are constantly rocked by arms 2 extending from the crank shaft. Each pawl has a depending lever 8 for engagement, on alternate strokes of the lever 3 during the normal operation of the loom, with a rod 12 which is pivoted on the loom frame. The rod 12 has a yielding connection with a rod 13 which has a vertical movement imparted to it by a cam 15 rotating at one fourth of the speed of the crank shaft, the upward and downward movement of the rod 13 causing the rod 12 to move out of and into the path of the pawl lever 8 and thereby effect engagement and disengagement of the members 3 and 7. In a modification the lay and the swing levers are provided with electromagnets which are energized at the appropriate times by means of a rotating switch under control of a shuttle feeler. In an hydraulic arrangement the connecting rods 2 are formed as piston rods and are slidably mounted in cylinders carried by a pivotally mounted lay whilst a further modification has a pivoted lay with mechanically operated clutches for engagement with slidably mounted connecting rods, the cylinder valves and the clutches being operated from the driving gear of the loom. Stop-motions, shuttle and the like.-When a shuttle fails to complete its course across the stationary lay, the appropriate swell 25, Fig. 2, maintains its position within the shuttle box and a feeler lever 24, in contact therewith, positions a lever 22 in the path of a booster 21 thereby preventing upward movement of the lever 12, and release of the pawl 7. The yielding connection of the rod 12 with the rod 13 permits the latter to complete its upward movement under the influence of the cam 15 and in so doing the lever 17 is rocked into the path of a booster 19 on the frame 3 which on its return stroke projects the rod 17 against a stop lever 20 and stops the loom. Actuation of the stop lever 20 may be effected on the forward stroke of the swing lever 23.

Patent GB-238938-A (GB)
Title: Partial oxidation of paraffin hydrocarbons in the gaseous phase
Filed: 1924-05-26
Abstract: Paraffin hydrocarbons containing more than one carbon atom in the molecule are partially oxidized in the vapour phase at a temperature between 620 DEG  and 850 DEG  C., each hydrocarbon molecule being subjected to the said oxidation temperature for such a period of time that a result is obtained approximating to that obtainable by subjecting the same molecule to a temperature of 700-710 DEG  C. for a period of a little less than one second.  An example is given of the oxidation of ethane with air or oxygen at a temperature of 700-710 DEG  C., the circulation of the gas mixture being such that a molecule of ethane passes through the furnace in a little less than one second.  The condensed product consists of an aqueous solution of formaldehyde together with some acetaldehyde, while the exit gases contain ethyene which can be removed say by absorption in acid. Propane, butane and higher paraffin hydrocarbons may be similarly treated, when not only are formaldehyde and ethylene produced, but also some of the higher olefines.  Gas mixtures containing the paraffin hydrocarbons together with olefines, for example coke oven gas, may be oxidized in the same way.  A silicious or vitreous heating surface, for example one of pure silica, is preferred.

Title: Testing nuclear fuel rods
IPC: G21C17/07
Filed: 1974-03-22
Abstract: 1468702 Testing fuel elements SIEMENS AG 22 March 1974 [23 March 1973] 12998/74 Heading G6C [Also in Divisions H3-H5] In a method of testing a nuclear fuel rod which has been used in a water-cooled reactor, a region thereof is heated and testing apparatus employed externally of the rod to subject the rod to an investigation the results of which are recognizably different in a case in which water is present in the heated rod from a case in which no water is present therein. Although decayheat for the nuclear fuel may be employed, preferably an external induction heater is used to heat a region of the fuel rod adjacent an end cap. In one embodiment, the heater coil 4 is carried by a tubular structure 42 to the interior of which a gas can be supplied (through conduit 6) to displace water from the-region of the coil 4 (the test being conducted whilst the rod is submerged). The structure also carries a temperature sensor 5, a Peltier element 7 and an ultrasonic head 3. When the rod is heated, any water in the rod is vaporized. Ultrasonic detection of steam bubbles or condensate drops can thus be employed; alternatively, temperature variation of the end cap as a function of time can be employed; or the quantity of heat supplied can be employed; if the heater is operated intermittently, the number of heating impulses required to reach a particular end cap temperature can be employed for determining whether the fuel rod is leaky.
