Title: Improvements in or relating to hypodermic injection apparatus
IPC: A61M5/46
Filed: 1953-03-04
Abstract: 735,538. Hypodermic syringes. TRANSUE, G. O. March 4, 1953, No. 6054/53. Class 81 (2). A hypodermic syringe injector apparatus comprises a syringe support which is slidably mounted in a casing structure comprising two telescopically connected tubular members and retaining means adapted to hold the support in a retracted position against the action of resilient means, the arrangement being that relative axial movement of the said tubular members is effective to disengage the retaining means so as to release the support for projection by the resilient means and consequently carry with it the hypodermic syringe and bring the needle to a projected position. The apparatus shown comprises a syringe 11 enclosed within a support sleeve 17 carried by a casing structure formed by telescopically connected sleeves 18 and 19. The syringe is provided with a flange 15 such that it also moves when the sleeve 17 is retracted relatively to the casing structure. The sleeve 19 is provided with radially offset grooves 35, 37, and the sleeve 17 with a groove 36 whilst the sleeve 18 is provided with ballcariying apertures 34. A spring 24 is provided between the sleeves 17 and 18. In use, when it is desired to " cock " the apparatus, the cylinder 19 is held whilst the head 30 is pulled in the direction of the arrow A (Fig. 2). This pull effects compression of the spring 24 and the movement of sleeve 17 from the position shown in Fig. 1 to its position of Fig. 2. At this point one or more of the balls 33 carried in the apertures 34 will drop into the groove 36 thereby preventing further movement of the sleeve 17 in the direction A relatively to the sleeve 18. On exerting a further pull sleeves 17 and 18 will move together in direction A the balls 33 all being forced into the groove 37 where they will be frictionally retained, this retention effecting the "cooking " of the various moving members of the apparatus in the positions shown in Fig. 3. For operational purposes the sleeve 18 is grasped and the face 42 of the adjustable sleeve 40 placed against the patient's skin with sufficient pressure to cause the sleeve 19 to shift relatively to the sleeve 18 to the position of Fig. 2. The spring 24 then effects injection of the needle 13 prior to the manual injection of medicament by projecting the syringe plunger 12.

Title: The production of lyophilised preparations
IPC: F26B5/06
Filed: 1956-02-27
Abstract: A process for producing stable chemical preparations including at least two components which are incompatible in common solution consists in successively freezing separate solutions comprising said components within a common vessel to form a stratified frozen mass and thereafter freeze-drying said frozen mass.  In one example of the process, a flask of 5 c.c. capacity was filled with 3 c.c. of an aqueous solution of 20 mg. of glycine and 2 mg. of gelatin per c.c. and placed upon a metal plate cooled to about -85 DEG C. by a mixture of carbon dioxide and acetone so as to freeze the solution. Thereupon, 1 c.c. of a similar solution, together with 10 mg. of a sodium salt of 7-acetamido-4-(sulphamyl-phenylazo) - 1 - naphthol - 3,6 - disulphonic acid, a strong red dyestuff is added to the flask. Upon freezing of the added solution, the whole is freeze-dried at an initial temperature of -40 DEG  C. and an absolute pressure of 0.01 mm. of Hg, the temperature being gradually raised to 40 DEG  C.  The resulting product has a lower white layer and an upper cherry red layer.  In another example, the above process was repeated with 2 c.c. of an aqueous solution of 45 mg. of sodium bicarbonate and 40 mg. of cane sugar per c.c. as a lower layer, and 2 c.c. of a solution of 25 mg. of citric acid and 40 mg. of cane sugar. Following freeze-drying there was obtained a finely-structured mass consisting of two distinct layers.

Filed: 1975-02-14
Abstract: 1483396 Hydrostatic transmission control COAL INDUSTRY (PATENTS) Ltd 6 Feb 1976 [14 Feb 1975] 6338/75 Heading F2W [Also in Division G3] A control for a hydrostatic transmission having a pump 4 delivering to a motor 6 driving mining equipment comprises a pilot valve 14 which, when return line pressure 8 falls below a predetermined value, opens a by-pass valve 10 to vent the high pressure line 5. The valve 14 is biased by a spring to an open position in which the high pressure line 5 is connected through lines 70, 72, a fixed throttle 76, a line 45 and the valve 14 to a reservoir. The pressure drop across the throttle 76 opens the by-pass valve 10. When the valve 14 is moved manually to the closed position shown the valve 10 closes and the pump 4 drives the motor 6. The pressure in the return line 8 acts on the end of the spool of the valve 14 to hold the latter in its closed position against the bias of the spring. If the high pressure 5 exceeds a predetermined value it opens a valve 12 and passes therethrough to act on the spool of the valve 14 and assists the spring to open the valve 14 and thus vent the line 5 through the valve 10. The line 5 remains vented until the valve 14 is manually reset. If the pump delivery falls due to stoppage of a driving electric motor 2 or other cause, the reduction in pressure in the return line 8 transmitted to the valve 14 permits its spring to open the valve and thus vent the line 5 which remains vented until the valve 14 is manually reset.
