Title: A ditch-digging or -clearing attachment for a tractor
IPC: E02F5/02
Filed: 1959-05-06
Abstract: 921,382. Ditch-cleaning implements. R. SMALLEY. May 4, 1960 [May 6, 1959], No. 15480/59. Class 68 (1). A ditch-cleaning attachment for a tractor comprises a frame 1, 5, 6, 19, 20 that can be secured to the lift linkage system 4 of the tractor, a scoop 7 pivoted at 27 to the frame, and a cable and linkage system 18, 16, 15, 13, 12, 10, 8 extending between the scoop 7 and a fixed point on the tractor. On vertical swing- ing of the frame by the lift linkage a pivotal movement of the scoop is automatically caused towards or away from the loading position of the scoop, the direction of this movement being dependent upon the direction of movement of the frame.

Abstract: 1,180,185. Lasers. TECHNIDYNE Inc. 1 April, 1968 [20 April, 1967], No. 15514/68. Heading H1C. [Also in Division G2] An optical sighting device or straight edge comprises a tubular gas laser arranged to emit aligned, collimated and focused light at both ends. As shown in Fig. 1, the gas laser 10 comprises a gas discharge tube 12 with Brewster angle windows 20, which is coaxially mounted in a cylindrical housing 14 by elastomer shockabsorbing rings 16. The optical resonator is formed by partially-transmitting mirrors 24, and each output path includes a transversely adjustable collimating lens 28 and a longitudinally adjustable objective lens 30. A laser straight edge is shown in Fig. 3 in which the gas laser 10, Fig. 1, is supported by elastomer ring mounts 44 in an outer easing 46 closed at its ends by optical windows 48. Sighting telescopes 52, 54 for the two directions of emission are detachably mounted on the casing 46. In a further embodi. ment, Fig. 4, parallel laser reference beams 74, 76 are provided by gas laser 10 which is vertically mounted within an inner tube 68 by elastomer rings 70, 72. The inner tube, in turn, is mounted within an outer tube 78 by integral support rings, the lower support ring 82 engaging a sliding ring 82A to permit relative movement. Parallelism of the emitted laser beams 74, 76 is effected by pentaprisms 96, 98 which are clamped to support plates 114. Alignment of the beams into the same direction is carried out by rotating movable end caps 88, 90 to which the plates 114 are respectively secured. The ends of the outer tube are terminated by housings 84, 86 having windows 100, 102 for the laser beams. Further windows 128, 130 are provided for optical paths 126, 128 extending from a sighting telescope 134 through a prism 136 and a pentaprism and beamsplitter (118, 120), Fig. 5 (not shown), the sighting telescope being used for alignment adjustment by observing laser beam reflections from a distant target. A beam splitter (170) may be added to pentaprism 96, Fig. 9 (not shown), to provide a laser beam in the direction opposite to beam 74. In use, the assembly is vertically mounted on a tripod by a gimbal mount, Figs. 7 and 8 (not shown), with the base in engagement with a screw adjustment.

Title: Novel macrocyclic thialactones and process for the preparation thereof
IPC: C11B9/00
Filed: 1958-05-14
Abstract: The invention comprises macrocyclic thialactones of the general formula:  <FORM:0859392/IV(b)/1> in which R1 and R2 represent branched or non-branched carbon chains, the total of the number of carbon atoms in the ring amounting to from 10 to 20 inclusive.  The novel compounds may be prepared by subjecting hydroxy-thiacarboxylic acids of the formula HO-R1-S-R2-COOH to lactonization, e.g. using a highly diluted solution in an inert solvent in the presence of benzene sulphonic acid, by depolymerization of the polymerized hydroxy-acids, or starting from the glycerol esters in the presence of an esterification catalyst, for example, sodium methylate.  The hydroxy-thiacarboxylic acids may be prepared by addition of mercapto-carboxylic acids to alkenols or of mercaptoalkanols to alkenyl carboxylic acids, preferably using an initiator yielding free radicals under the reaction conditions, for example an aliphatic azo compound such as azo-isobutyric nitrile.  The hydroxy thiacarboxylic acids can also be obtained by reaction of a halide with a mercaptide. Examples describe the preparation of 3-thiatetradecanolide, 2-thiatetradecanolide, 12-thiapentadecanolide, and 12-thiahexadecanolide and the corresponding intermediate hydroxy acids.ALSO:Soaps contain one or more scenting agents of the general formula R1-S-R2-COO in which R1 and R2 represent branched or non-branched carbon chains, the total number of carbon atoms in the ring being from 10 to 20 (for preparation see Group IV(b)).ALSO:Scents and perfumed products contain one or more compounds having the general formula: <FORM:0859392/VI/1> in which R 1 and R2 represents branched or non-branched carbon chains, the total of the number of carbon atoms in the ring being from 10 to 20 (For preparation see Group IV (b)).  In an example, a perfume composition comprises 12-thiahexadecanolide, castoreum resinoid, hydroxycitronellal, undecylenic aldehyde, Base 9391 and Base RL 30 (both available from Chemische Fabriek Naarden), a C14 aldehyde, civette tinct, a C 12 alcohol, coumarin, benzyl salicylate, and the following deterpinated oils; vetiver oil acetylated, vetiver oil bourbon, patchouli oil, cedarwood oil, bergamot oil, ylang ylang oil, nut oil, spanish rosemary oil and cardamom oil.

Title: Improvements relating to centrifugal separators

IPC: B04B11/08
Filed: 1958-10-09
Abstract: 906,269. Centrifugal strainer separators. AMETEK Inc. Oct. 9, 1958, No. 16017/62. Divided out of 906,268. Class 46. A plough P is moved by hydraulic motors through a predetermined cycle of operations, the running of the motors being governed by hydraulic control means initiated manually or automatically. Preferably also the basket B is driven by a hydraulic motor 38, and an electric circuit including timers is provided to enable a cycle of operations of the whole apparatus to be performed and repeated automatically. When the circuit is switched on, the basket begins o rotate at "unloading" speed (e.g. 50 r.p.m.) provided that a hinged cover 40 (governing a limit switch) is closed. Then the plough P is turned towards the basket, is lowered to remove any solids left from a previous cycle, is raised; and finally is turned back to its original position. Next, the basket is accelerated to "loading" speed, and, when this is attained, mixture to be centrifuged is fed for a predetermined time through a pipe F including a solenoid-operated valve 44 and ending in a nozzle 43. Feeding may be facilitated by a steam jet incorporated in the feed pipe. A load-indicator limit switch may end the feeding phase before the expiry of the pre-determined time if the basket is then sufficiently loaded. Next, the basket is accelerated to "extracting" speed, and runs at this speed for a period sufficient to permit the removal of mother liquor and the (timed) introduction and removal of one or more wash liquids conveyed through one or more pipes 45 each ending in jets 47. Next, the basket is decelerated to unloading speed, whereupon the cycle of operations of the plough is again initiated, and the full cycle is repeated. The durations and inter-relation of the various phases may be varied; e.g., extracting and washing may take place whilst the basket is running at only loading speed, prior to a short high-speed phase; or feeding, extracting and washing may all take place during the highspeed phase. Another circuit which may be used includes the following further features; an unbalance limit switch which opens if the basket gyrates excessively; timers to provide for a preliminary wash and extraction before feeding of the material to the basket and, after mother liquor extraction, two separate washes with an extraction period in between; and control for a filtrate valve which serves to direct filtrate either to a process line with which the separator is employed, or to a sewer line. A disc 28 may be provided to cover solids discharge openings 27 but it must be removed prior to solids discharge.
