Title: Improvements relating to the operation of movable heads of vehicles
IPC: B60J7/12
Filed: 1937-10-29
Abstract: 499,993. Vehicle opening-tops electric motor control systems. OVERTON, W. Oct. 29, 1937, No. 29570. [Class 108 (i)] [Also in Group XXXVII] In a vehicle having a roof aperture closable by a sliding panel or equivalent electrically operated member, a nut 14 or like screw-actuated element is adapted at the limits of its travel, corresponding to the extreme positions of the sliding panel &c., to actuate switches for stopping the electric motor which drives the main operating-shaft 5 for moving the sliding panel and carrying the nut &c. 14. In the construction shown a reversible electric motor 6 is controlled by a pair of press button switches 31, 32, which are adapted to be closed by a hand-actuated universally-jointed switch lever 25, which is guided by a vertical plate having a straight slot 23 terminating in bayonet portions 29, 30. The end 28 of the lever 25 can be displaced from the bayonet portions of the slot, in which position one or other of the switches 31, 32 is closed, by means of pivoted levers 18, 19, which are actuated when a pin 15 on the nut 14 reaches the limits of its travel in a guide slot 16, Thus, when the hand lever 25 has been engaged in one bayonet slot 29 or 30 to start the motor 6 and cause the shaft 5 to be driven through gearing 8, the nut 14 and pin 15 will be traversed until the latter contacts with and rocks one of the levers 18 or 19, causing the end 28 of the switch lever to be displaced and stopping the motor. In addition, owing to the fixed abutment afforded by the pin 15, the motor cannot again be started in the same direction, thus preventing straining of the operating-mechanism and sliding panel. A readily disconnectible handle 10 may be provided for manual operation of the shaft 5 when desired.

The door is provided with rearwardly projecting arms 30 which lie under shelves 31 to hold the door in its horizontal position. The upper side 32 of the door 16 is pivotally mounted to provide a lid for a chamber 38 formed by battens 34 surrounding the door.
Patent GB-830738-A (GB)
Title: Improvements in or relating to methods for the thermal treatment of aqueous liquors
IPC: B01D3/14
Filed: 1958-09-16
Abstract: Aqueous liquors are distilled or concentrated by conducting into the liquors vapours of a thermally stable organic substance (or a silicone) which is immiscible with water and has a higher boiling-point or range than the liquors and a different specific gravity and allowing the vapours to condense in the liquors at such a rate that the liquors are heated to boiling and distil. The process is suitable for heating corrosive liquors, e.g. in concentrating dilute hydrohalic acids or aqueous solutions of non-volatile acids, such as sulphuric and phosphoric acids, or acid salts, such as primary and secondary phosphates and bisulphites, or salts which are hydrolysed, such as magnesium chloride, or in the removal of aqueous acid by distillation from reaction mixtures which liberate acids, such as the interaction of alkali metal chloride and phosphoric acid to give phosphate and hydrogen chloride.  The "heat carrier" whose vapours are used to heat the liquors preferably has a boiling-point at least 100 DEG  C. above that of the liquors.  Suitable substances include hydrocarbon fractions, particularly those stripped of aromatic hydrocarbons and substituted hydrocarbons such as trichlorobenzene.  Silicones may also be used.  In continuous operation the organic layer may be removed from the distillate and the residue and recycled.

Title: Improvements in and relating to apparatus for the manufacture of glass tubes provided with closed ends or bottoms
IPC: C03B23/11
Filed: 1924-12-15
Abstract: 242,213. Glaswerke Ruhr Akt.-Ges. Nov. 1, 1924, [Convention date]. Shaping glassware after formation.-Relates to a machine of the kind described in Specification 177,884 for forming an open-ended tube into two tubes with closed ends, such as tablet tubes. According to the invention, the closed ends of the tubes are flattened by means which prevent them from being spread out or deformed. The ends of the tubes are flattened by means of plates a, Fig. 1, fixed to the inner sides of the bars b that lift the finished tubes away from the place at which they are formed, as described in the earlier Specification. A glass tube c, Figs. 1 and 3, rests on and is rotated by rollers 1 while it is being heated at the middle by a burner 21. After it has been heated sufficiently, the rollers 1 are separated to draw the ends of the tube apart and form two tubes having closed ends. When the separation is complete, the bars b are raised so that the plates a stand between the closed ends of the tubes: the rollers 1 are then moved inwards so that the ends of the tubes are pressed against the plates a and are flattened. The tubes are held in contact with the rollers 1 by means of discs 5 which are pressed against the tubes by springs. The pressure is adjusted to such an amount that when the tubes are brought up to the plates a, the rollers 1 will slide along the tube if the pressure of the tubes against the plates becomes excessive, thus preventing the flat bottoms formed on the tubes from being spread out.
