Abstract: 283,850. Jorgensen, E. H. H. Jan. 17. 1927, [Convention date]. Locks for valves. - Actuating and locking means for valves and cocks comprises a rotary lock bolt or tumbler plate 11 disposed on the valve spindle 6 and having fingers 13 which are held in engagement with recesses 14 in the casing cover 3 by a spring 16. The valve spindle comprises two cylindrical portions 6, 9 separated by a recessed part 8, the cylindrical portions being each formed with a flat part 7, 10 in displaced relation. The tubular key handle 4 is formed with an inwardly projecting flat portion 17 which first passes the upper flat part 10 of the spindle and after a partial rotation in the recess 8, slides down the flat part 7 into the position shown. For opening the valve the key is first depressed to disengage the tumbler plate 11 from the casing part whereupon the key and spindle can be rotated to open the valve. In this position an inturned projection on the key handle engages under the flange 20 on the casing so that in the opened position the key handle cannot be removed. To prevent the lifting of the plug when removing the key a portion 21 of the casing is bent over a conical portion of the plug, or a screw is substituted for the part 21.

Title: Monoperoxyacetals and the preparation thereof
Inventor: ROPP WALTER SHADE
IPC: C07C409/20
Filed: 1955-12-09
Abstract: The invention comprises monoperoxyacetals of the formula CH3.CH(OR).OOR1 in which R and R1 are hydrocarbon radicals containing no ethylenic or acetylenic unsaturation, e.g. R may be ethyl, isobutyl or dihydroterpinyl, and R1 may be a -cumyl or p-methyl radicals.  The new compounds may be prepared by reacting a vinyl ether CH2 = CH-OR with a hydroperoxide R1OOH, where R and R1 are as defined above, in a non-aqueous medium in the presence of an acid-acting condensation catalyst.  Suitable vinyl ethers are dihydro-a -terpinyl-, bornyl, isobornyl, fenchyl, dehydroabietyl, cyclohexyl, 1-methylcyclohexyl, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl or stearyl, vinyl ethers. Typical hydroperoxides are t-butyl, t-amyl, cumene, p-cumene, p - cymene, di - isopropylbenzene, phenylcyclohexane, p - menthane, isopropylnaphthalene, or pinane, hydroperoxides.  Catalysts such as mineral acids, Friedel Crafts catalysts, acid clays and organic sulphonic acids may be used in amounts of 0.05 per cent to 5.00 per cent of the reaction mixture.  Benzene and hexane are suitable solvents.  The reaction may be effected at room temperature, a preferred range being 0 DEG  C. to 30 DEG  C.  At temperatures above 80 DEG  C., short reaction times are necessary to avoid decomposition. Detailed examples describe the preparation of peroxyacetals of formula CH3.CH(OR).OOR1, where (1) R is dihydroterpinyl and R1 is a -cumyl; (2) R is ethyl and R1 is a -cumyl; (3) R is isobutyl and R1 is p-menthyl; (4) R is isobutyl and R1 is a -cumyl, by reacting the appropriate vinyl ether and hydroperoxide in benzene solution using boron trifluoride or p-toluene sulphonic acid as the catalyst.  The monoperoxyacetals find use as polymerization catalysts, insecticides, fungicides, bactericides and defoliants.

Abstract: 1,121,531. Obtaining filtered samples of of liquid. FISONS FERTILIZERS Ltd. 14 Oct., 1966 [19 Aug., 1965; 26 Feb., 1966], Nos. 35523/65 and 8573/66. Heading B1D. In obtaining a filtered sample of liquid for analysis in order to check progress in a chemical reaction, a leaf filter element with one pervious wall 1 is immersed in liquid to collect filtrate in its chamber 2, which filtrate is then expelled by compressed air from supply 4 which simultaneously backwashes the wall 1. The filling of chamber 2 may be effected by the head of liquid above the element, or a vacuum pump 9 may be used. When compressed air is delivered by line 3, valve 11 vents chamber 6 in which filtrate is collected to atmosphere. Filtrate leaves chamber 6 for analysis via valve 16. A water supply 13 is periodically used to flush the apparatus to remove deposited solids. Two such systems may be used alternately to supply samples continuously. In another embodiment a further filtrate chamber (20) is connected to filter element (21, 22) by a one-way valve (24), and filtrate expelled, from chamber (20) only, for analysis. The whole circuit is cleaned by wash water and air pulses, and emptied by air pressure prior to the next filling. The circuits may be timer-controlled.

The shaft a of the dial, Figs. 2, 3, carries by means of arms e a shaft f on which are mounted hooks g adapted to engage the driving members d of the respective registers Zm<1> .. Zm<3>. The driving members are of different lengths so that when the first digit is dialled only the first register is set and so on. The registers are latched by pawls h. When the fourth digit is dialled a fourth hook engages a fourth member d to operate contact springs. The registers are unlatched by the replacement of the receiver. Electrical control of registers, Fig. 7. Relay JR repeats the digits to back stroke switches ZM<1> .. ZM3. VR<1> is energized throughout the operation and VR<2> during each digit. At the beginning of the first digit JZR <1> is energized and at the end JZR<2> energizes UR<1> which locks, holds ZM<1> and connects up ZM<2>. At the beginning and end respectively of the second digit, JZR<1> and JZR<2> are shunted out and UR<2> holds ZM<2> and connects up ZM<3>. The 3rd digit re-operates JZR<1>, JZR<2> to energize HR which holds ZM<3>. The 4th digit energizes HR<1> which operates contact IV. Indicating fee and controlling breakdown at substation, Fig. 1. The registers select lamp circuits to indicate the fee. The arm Mza is stepped round to a position characteristic of the coins inserted. If the correct fee has been inserted, K is energized and cuts off T which would otherwise be energized over contact IV by the dialling of the fourth digit to break down the connection. Coin collecting and forced release circuits at exchange, Fig. 6. Relay U in the line circuit and C in the test circuit pull up followed by X. In the case of long-distance calls, the reply of the called subscriber initiates the transmission of impulses characteristic of the charge over the wire d to a meter Z<3>. Z' is operated in parallel and energizes Z<2> which locks up. X holds only until the impulses cease and then falls, disconnecting Z<3>. After 3 minutes a further impulse is sent to the d-wire and Z<1>. then energizes K<1> which disconnects the loop from the exchange circuits to release the connection and connects it to a source of A.C. to operate a collecting magnet K<2>. In the case of local network calls, impulses are not sent to the d-wire until the release of the connection and consequent relapse of U. In this case Z<2> operates K<1> immediately to collect the fee.

Title: Process for the production of wax-like ethylene polymers and ethylene co-polymers of low molecular weight
Inventor: RAETZSCH MANFRED
IPC: C08F8/50
Filed: 1965-08-20
Abstract: Wax-like ethylene polymers of low molecular weight and predominantly linear are prepared by the thermal decomposition of ethylene polymers of high molecular weight and to some extent ramiform, said decomposition being carried out in an atmosphere free of air and oxidizing agents, the polymer to be decomposed being mixed with a melt of already decomposed ethylene polymer, and the decomposition being then carried out at 300 DEG  to 600 DEG  C. for 30 seconds to 5 hours.  The process may be applied to ethylene homopolymers and copolymers, batchwise or continuously, and radical forming agents and molecular weight regulators may be added before or during the decomposition.  The process may be effected in a stirred vessel in the lower part of which may be a coiled flow pipe through which the product may be withdrawn and passed to a granulating device. Examples describe the preparation of waxes from (1, 4 and 6 to 9) polyethylene, (2) an ethylene/vinyl acetate copolymer, (3) polyethylene in the presence of dicumyl peroxide, and (5) an ethylene/carbon monoxide copolymer. The products may be used in polishes and for coating paper.

A device for cutting a main or branch pipe along a line of intersection between the main and branch pipes which run into each other at any desired angle, comprises a cutting- tool 54, particularly a cutting torch, which is moved axially of the pipe 70 to be cut by the differential movement of a first crank 19 and a second crank 27 driven at half the speed of the first crank, and means for oscillating or rotating the pipe during cutting. A motor 1 drives the crank 27 through shaft 2, worm 5, worm-wheel 6 and sleeve 26. Bevelgear 7 fast with worm-wheel 6, meshes with planet gear 8 mounted on a perpendicular arm 16 of a shaft 76 secured to first crank 19. Gear 8 meshes with gear 9 fast with worm-wheel 10 meshing with worm 11 on shaft 12 which is normally held stationary to cause shaft 76 and hence crank 19 to rotate at half the speed of gear 7 and crank 27; shaft 12 is, however, adjustable by handle 15. Cranks 19, 27 carry adjustable crank-pins 21, 29 movable in slotted guides 22, 30 of rods 23, 31 slidable in bearings 24, 25 and 32, 33. Rods 23, 31 have rack teeth 34, 35 meshing with pinions 36, 37 fast with bevel gears 40, 43 of a differential whose planet-gear 44 drives a shaft 46 and pinion 47. The latter meshes with rack teeth 48 on a slide bar 49 carrying the cutting torch 54. Motor 1 also drives through gears 57, 58, worm gears 62, 63 and shaft 64, an oscillating mechanism 80-84, Fig. 2 (not shown) of the kind described in Specification 767,233, which causes the main pipe 70 to be oscillated about its axis in synchronism with the axial movement of torch 54 whereby a portion 71, 72 is cut from pipe 70. For cutting the end of the branch pipe, the oscillating mechanism is omitted and the pipe is rotated during cutting. Equations are given for determining the effective lengths of the cracks 19, 27 in terms of the radii of the main and branch pipes and their angle of intersection.

Filed: 1972-08-01
Abstract: 1365202 Accelerator pedal DAIMLERBENZ AG 1 Aug 1972 [4 Aug 1971] 35929/72 Heading B7H An accelerator pedal arrangement for a motor vehicle includes a shaft 4 which is pivoted in bearings 1, 2 on the vehicle floor 3, two levers 5, 6 fixed to the shaft 4, the lever 5 being connected to the accelerator cable (not shown), a pedal plate 10 which is pivoted by bearings 8, 9 on a shaft 7 fixed to the lever 6, and a pair of stops, the arrangement being such that if the driver presses above the. shaft 7 the pedal 10 rotates about the axis of shaft 4 and if the driver presses below the shaft 7 the pedal plate 10 rotates about an axis at the top of the plate 10, thus turning the lever 6 and shaft 4. As described a sleeve 12 is rotatably mounted on the shaft 4 and carries a stop 16 and a lever 13 having a slot 14. The pedal plate 10 carries a rod 15 which engages the slot 14 and an angled stop member 11. When the driver presses above the shaft 7 the stop 11 engages the back of the lever 6 so that the plate 10 and lever 6 rotate about the axis of the shaft 4, thus turning the shaft. During this movement the sleeve 12, lever 13 and stop 16 also rotate freely about the shaft 4. When the driver presses below the shaft 7 the stop 16 prevents the lever 13 from rotating so that the plate 10 rotates about the axis of rod 15, thus turning the lever 6 and shaft 4. This arrangement facilitates simultaneous operation of the brake and accelerator, the driver applying his toe to the brake pedal (not shown) and his heel to the bottom of the accelerator pedal and for this reason the bottom of the pedal plate may be widened as shown.
