Title: Improvements in sea anchors
IPC: B63B21/48
Filed: 1941-08-29
Abstract: 550,546. Drag anchors. CHIPCHASE, R. S. Aug. 29, 1941, Nos. 11050 and 12318. [Class 114] In a drag anchor comprising a hollow truncated cone or pyramid 1 of canvas or like flexible material which is drawn through the water with its larger end forwards, the cone is mounted on a rigid frame structure which supports it throughout its length, and/or a square or circular transverse baffle plate 3 is located just behind the smaller end. The rigid frame comprises main supporting arms 5 pivoted at 6 to the plate 3, and stay rods 7 pivoted to the arms 5 and to a slider 8 which slides on a central rod 4 of oval cross-section. Forward movement of the slider 8 is limited by a shoulder on the rod 4, and it is retained in that position by a split pin passing through the rod 4. The edges of the cone 1 are strengthened by ropes 15, and a cylindrical canvas cover is provided for the anchor when collapsed.

Title: Process for production of acetylene by regenerative thermal decomposition of hydrocarbons
IPC: C07C4/02
Filed: 1962-03-22
Abstract: Acetylene is obtained by the regenerative cracking of a hydrocarbon mixed with a diluent consisting of both hydrogen and steam in a molar ratio of 20: 80 to 90: 10, preferably at above 850 DEG C. The hydrocarbon may be gaseous or liquid and may be a mixture.  Cracking is effected in a regenerative or pebble-type heater.

Title: Hydraulic mechanism for controlling reciprocation of grinding machine table
Inventor: STOLBOV LEONID SIDNEEVICH
IPC: B24B47/06
Filed: 1970-03-09
Abstract: 1,274,790. Grinding machine tables. EKSPERIMENTALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT METALLOREZHUSCHIKH STANKOV. 9 March, 1970, No. 11205/70. Heading B3D. [Also in Division F1] An hydraulic mechanism for controlling reciprocation of a grinding machine table 2 by means of an hydraulic piston/cylinder unit 62 comprises a reversing valve 4 for directing fluid to the unit 62 and a control valve 5 for causing the fluid to actuate the reversing valve 4 when a stop 67 connected to a gear-wheel 58 engaging a control valve rack 57 is rotated by engagement with a table traverse limiting stop 65 or 66, throttle valves 16-19 being provided to govern the table reversal delay and acceleration. In the position shown, pressurized fluid from an input line 59 acts through annular bore regions 28, 30, a line 60 and a cylinder region 73 to move the table 2 to the left, the pressure acting through a passage 45, bore region 36, port 52 and control valve bore 50 to urge the valve 5 to the right relative to a fixed plunger 11; fluid forced out of the opposite cylinder region 74 exhausts through a line 61, bore regions 29, 31, a port 41, bore regions 33, 39, a port 40, a line 63 and throttle valves (not shown) for controlling the table speed. When the stops 65, 67 engage, rotation of the gear-wheel 58 moves the valve 5, through the rack 57, to the left against the pressure in the bore 50. A bevelled valve edge 55 gradually blocks fluid flow between the bore regions 33, 39, blocking flow from the cylinder region 74 and braking the table to rest. Engagement of a valve member 5B in an outer orifice of the valve body 3, and establishment of fluid flow connection around a reduced portion 53 of the valve 5, allows input fluid to flow from the passage 45 through bore regions 35, 37, passages 43, 78, a one-way valve 12 and the throttle valve 16 into a chamber 77, thus urging the reversing valve 4 to the left, fluid escaping from an opposing chamber 76 through passages 48, 75, 44, around a valve member 5A (cf. 5B as shown), and through passages 24, 46, 64 to drain; when the valve 4 blocks the passage 48 exhaust continues through the throttle valve 19 causing a braking effect. Fluid flow through the bore region 28, a further region 29 and a line 61 causes a return movement of the table 2 until the stops 66, 67 engage, causing a further reversal sequence.

Title: Improvements in and relating to the preparation of aminocarbinols
Inventor: MURFITT HARRY CHARLES
Filed: 1955-04-19
Abstract: Secondary aminocarbinols of the general formula: <FORM:0787668/IV (b)/1> are prepared from b -aminoketones of general formula C6H5CO.CH2.CH2.NHR in the form of their hydrohalide salts, by reaction with a cyclohexyl organo metallic reagent, e.g. cyclohexyl magnesium halide or cyclohexyllithium (where R is an alkyl group with 1-3 carbon atoms).  In an example 1-cyclohexyl-1-phenyl-3-methylaminopropan-1-ol is prepared by refluxing a mixture of b -methylaminopropiophenone hydrochloride with a solution in ether of a Grignard reagent obtained by reacting cyclohexyl chloride with magnesium and iodine.  The resulting mixture is cooled in ice and acetic acid and then warmed to not more than 50 DEG  C. in order to distil off the ether. Excess ammonia solution is then added and the solid which separates out filtered and precipitated with an equal volume of acetone and water. 1-cyclohexyl-3-ethylamino - 1 - phenylpropan - 1 - ol is prepared by a similar method using 2-ethylaminopropiophenone hydrochloride and cyclohexyl magnesium chloride.  Specification 786,612 is referred to.

Title: Coin paying machine

Abstract: 198,525. Brandt, E. J. April 25, 1922. Money-delivering apparatus.-Relates to improvements in change giving machines of the type described in Specification 189,153, which is now adapted to British currency. In one form the keys are marked with the price to be paid and the proper change is automatically given on depression of the key indicating the purchase price. The keys may, however, be marked with the change to be given, when, if the machine is working on other than the normal tender basis, the operator depresses keys indicating the change which would have been required had the normal tender been made, the machine automatically adjusting the amount delivered so that proper change is given. The machine is adapted to be converted from a half-crown or five shilling normal tender basis to one, two, three or four shilling bases by means of converter keys 32 - - 35 respectively. Each converter key operates a converter plate 24 mounted on screws 26 and capable of independent reciprocation. Each plate 24 has a depending lug 36 formed with an inclined slot 37 in which fits a stud 38 carried by the operating key, the depression of the key forcing the plate 24 laterally and allowing the cams 31 on the plates to set the coin ejector fingers. When the keys 32 - - 35 descend a locking catch 39 carried on each key passes over a bar of a spring controlled locking rocker frame 40 and locks the key and the converter plate in their set position. On the operation of a key for the change which would have been required on a normal basis, additional coins are now ejected, the discharge of which is controlled by the converter plate 24 which has been put into operation by the depressed key. The coin ejector 20 of a stock of sixpenny pieces is controlled by a converter plate adapted to be operated by any one of the plates 24, a contact foot on the plate extending into the path of the ends of the plates 24 as they pass to their set positions, a cam on the plate setting or releasing the ejector finger and a spring restoring the plate to its normal position. To restore the machine to the normal tender a depending contact lug 51 on each carrier plate 15 strikes, as the carrier plate advances, the lower bar of the rocker frame and swings it, releasing the catch 39 and allowing the spring 52 to raise the key and force the plates 24 to their normal position.
