Title: Improvements in or relating to drawing apparatus
IPC: B43L13/14
Filed: 1953-04-08
Abstract: 747,728. Drawing-apparatus. CHALMERS, W. B. B. June 28, 1954 [April 8, 1953], No. 9571/53. Class 97 (3). Drawing apparatus comprises a frame member universally mounted at a fixed point, a tracer finger slidably mounted in the frame and having a tip portion set obliquely to the axis of sliding, which axis is such that the tracing point of the tip portion always lies on a radius from the fixed point, the tracer finger being also mounted for rotation about the said radius from the fixed point through the tracing point, and a writing member resiliently mounted on the frame so as always to be urged towards a writing surface in a direction radial to the fixed point. The universal mounting does not permit the frame member to rotate about the fixed point. As shown in Fig. I, the frame member comprises an L-shaped tubular member 1 supported at a fixed point 2 by a universal joint which may be gimbal-like. Brackets 3 on member 1, Fig. 4, support a spindle 4, which is rotatable about its own axis and carries brackets 5, 5a which terminate in wheels 6 grooved peripherally to support a square-sectioned member 7. The lower end of member 7 carries the tracing point 8, the end of which lies in line with the axis of spindle 4. A cord 10 fixed to an arm 9 at the top end of member 7 passes over pulleys 11, 13 and is connected to a counterweight 12 (not shown) movable within frame 1 in such manner that the centre of gravity of the system is kept constant. A pen 15 is guided axially in a tubular member 14 fixed to the short arm of the L-shaped member 1, and is urged against a drawing-board 15a by links 16a, 16b connected by a spring 16c. The common axis of members 14, 15 passes through point 2, and the drawing-board is at right angles to the mean position of this axis. An object of which a perspective view is to be drawn is mounted with the desired aspect facing point 2, and the tracing point is drawn over the features of the object to be reproduced. Movements along a radius from point 2 are taken up by longitudinal movement of member 7, but other movements are transmitted to pen 15. When desired, pen 15 may be raised from board 15a by a spring-loaded ball-pointed rod (not shown) mounted on and parallel to member 14 and movable towards the drawing-board by a flexible cable 19 with a finger or foot control 20. In a modification, the tracing point 8 and pen 15 are mounted on opposite sides of the member 1, instead of at right angles to each other, and spindle 4 is dispensed with, brackets 5, 5a being mounted in brackets 3 by means of stub axles and ball bearings. In further modifications, the frame member may be straight with the tracing point and the pen at opposite ends, and two or more drawings may be produced simultaneously by two or more pens. Specification 747,729, [Group XV], is referred to.

[Also in Division D1] A brake mounted inside the wharf of a textile spindle comprises means movable between a braking position in which it engages the inner surface of the wharf and an inoperative position clear of the wharf, means biasing the braking means towards the brake position and locking- means to releasably hold the braking means in the inoperative position. As shown, brake shoes 7 are slidable in radial slots in a member secured to a stationary blade 1. The brake shoes have slots in which cam surfaces 11 upstanding on an annular rotatable plate 8 engage. Plate 8 is biased to rotate by a spiral spring 14 in a direction such that cams 11 force shoes 7 into braking relation with wharf 3. By means of a radially extending arm (10), Fig. I (not shown), plate 8 may be rotated manually against the spring action to a position in which a latch on the arm engages a recess in the member 9 on blade 1. To operate the brake the latch is released allowing the brake to rotate plate 8 and brake the spindle.
Patent GB-713833-A (GB)
Title: Manufacture of 1:1:3-trialkoxy alkanes
Inventor: BELLRINGER FREDERICK JAMES
Filed: 1950-04-20
Abstract: 1 : 1 : 3 - Trialkoxy alkanes (the term "alkoxy" being used to denote the residue of an aliphatic or araliphatic mono- or polyhydric alcohol) are prepared by reacting an a ,b -ethylenically unsaturated aliphatic aldehyde with an aliphatic or araliphatic alcohol in the presence of an acidic catalyst and entraining from the reaction mixture the water as it is formed by the condensation reaction and any water initially present in the reaction mixture by distillation with an entrainer. Suitable entrainers are those which form an azeotrope or constant boiling mixture with water including hydrocarbons such as benzene, chlorinated hydrocarbons such as methylene dichloride or chloroform and ethers such as ethyl ether or di-isopropyl ether; the alcohol used in the reaction may also be used as the entrainer by providing it in suitable excess.  The process may be operated batchwise or continuously.  Thus, the alcohol containing an acid catalyst and the unsaturated aldehyde may be introduced continuously into a distillation column, the alcohol feed-point being at a higher part of the column and the entrainer is introduced at or below a point below the aldehyde feed point. Trialkoxyalkane and alcohol with or without entraining agent are withdrawn from the base and a water-entrainer distillate is removed overhead.  In this method the distillate may have a higher boiling point than the aldehyde as the major part of the aldehyde is reacted upon during its passage up the column.  When the distillate forms two layers the oil layer which contains any unchanged aldehyde distilled over, is returned to the column. Suitable catalysts are sulphuric, hydrochloric and phosphoric acids, aluminium chloride, organic sulphonic acids, acid clays and acid zeolites.  The process may be operated under reduced pressure. Specified reactants are acrolein, methacrolein and crotonaldehyde; methanol, ethanol, propanol, butanol, allyl alcohol, benzyl alcohol, ethyl hexanol, isopropanol and glycols such as ethylene glycol and trimethylene glycol.  The glycols yield products of the type <FORM:0713833/IV (b)/1> where n is an integer greater than one and R and R1 are either both hydrogen atoms or an hydrogen atom and an alkyl group, e.g. methyl.  Some of the alkoxy alkanes are said to be novel. The products may be hydrolysed to the corresponding alkoxy aldehydes.  Examples illustrate the production of (1) triethoxybutane; (3) tri-n-butoxybutane; (4) tri-n-propoxybutane; (5) tri-methoxybutane; (6) tri-ethoxy-2-methyl propane; (7) tri-n-butoxypropane; (8) tri-n-propoxypropane; (9) tri-isopropoxy propane; (10) tri-benzyloxy propane; (11) 2 - (51 - hydroxy - 3 - oxapentyl) - 1 : 3 - dioxan; (12) 2 - (61 - hydroxy - 3 - oxahexyl) - 1 : 3-dioxan; (13) 2-(51-hydroxy-11-methyl-31-oxapentyl)-1 : 3-dioxolan and 2-isopropenyl-1 : 3-dioxolan by-product, and (14) 2-(61-hydroxy-11-methyl - 31 - oxahexyl) - 1 : 3 - dioxan and 2-isopropenyl-1 : 3-dioxan by-product.

Abstract: PURPOSE:To regulate the rotation speeds of both drums according to loads and facilitate the running operation of a winch by providing such a constitution as switching a solenoid valve to connect a shuttle valve side circuit to a clutch hydraulic cylinder in the operation under a free falling mode state. CONSTITUTION:In the winding operation at free falling mode, a circuit on shuttle valves 231, 331 side is connected to the clutch hydraulic cylinders 201, 301. Thus, a low-pressure pressure oil passing a circuit extended from the pilot pressure oil circuit of an operation value is first supplied to the clutch hydraulic cylinder, and a drum is connected to a drum shaft 101 in the semi-clutch state, and when the pressure of the pilot pressure oil circuit exceeds the operation set pressure of pilot valves 211, 311, the pilot valves are switched, a high- pressure pressure oil passing the pilot valves is supplied to the clutch hydraulic cylinder to make the clutch in a complete connected state. Thus, in the state where the clutch of one drum is completely connected, the other drum can be connected in the semi-clutch state.
