Title: Device for control of feed mechanisms in machine tools
IPC: G05B19/04
Filed: 1955-12-09
Abstract: 793,473. Machine-tool details. WERNER, H. H., and RUDIGER, F., [trading as WOHLENBERG KOMM-GES., H.]. Dec. 9, 1955 [Dec. 13, 1954; Feb. 7, 1955], No. 35377/55. Class 83 (3). [Also in Groups XXIV XL (b)] A machine-tool comprises a counter having a pulse-transmitter 10, whose pulses are a measure of the amount of feed of a feed-element 38, an electronic-register 40, a digital entry registersetting means 21, and means by which the register emits an impulse after the preselected number of pulses to stop the feed. The rotation of the feed-screw 37 is measured by the number of pulses received by a photo-cell 11. The register 40 is set by a punched-card, or by the keyboard 21, the keys of which are illuminated when depressed. After a predetermined number of pulses prior to the stopping of the feed, the register acts to slow down the feedmotor 48, and a counter 43 then takes over and finally actuates the relay 45 to operate a prestressed and electromagnetically - operated spring brake to stop the element 38 and disengage the feed. Thus before the element is stopped, an electromagnet 213, Fig. 8, is actuated to stress a spring 215 attached to a lever 209. When, subsequently, an electromagnet 211 is operated to release a catch 210, the lever 209 is suddenly moved to release a friction-clutch 205, 204 and engage a frictionbrake 204, 212. Alternatively, the counter 43 may be replaced by an interselector which resets the register 40 for the remaining predetermined number of pulses. Since the machineelement will not stop dead, the counter may stop the feed before the full number of pulses have been received. In operation by punchedcard, the holes in the card may allow the ends of levers to be drawn therethrough by an electromagnet to operate the keys or separate contacts. Fig. 6 illustrates how a punched-card may be used for controlling the movements of the turret. in a lathe. The card may also include holes for governing the spindle-speed, rate-of-feed, change-of-stock, or for switching to another control. In a modification, there is an initial fast-feed actuated by every other pulse, followed by a slow-feed actuated by each pulse, thus giving a finer sub-division of the feed-movement.. Specification 777,092 is referred to.

Title: Improvements in and relating to suppositories
IPC: A61K9/00
Filed: 1935-12-23
Abstract: A suppository comprises a carrier which on melting at body temperature furnishes a liquid with which a gas-forming constituent, enclosed in the carrier in solid dry state and fusibly or solubly coated to exclude moisture, reacts to foam the carrier and spread a medicament incorporated in the carrier or in the gas-forming constituent throughout the body cavity.  The carrier may comprise a soft jelly, and the gas-forming constituent may comprise two dry interactable powders mixed together or separately with fusible or soluble moisture-excluding materials, and formed into square-section rods or other formed bodies, or into grains or lumps.  In a modification, gas may be sealed under pressure in a fusible or soluble capsule for enclosure in the carrier.  Fusible or soluble capsules may also be employed to enclose the gas-forming materials before embedding in the carrier, and to enclose the carrier itself. In an example, 55 grams of tartaric acid and 25 grams of sodium bicarbonate are mixed and finely ground and the mixture incorporated with a melted mixture of 60 grams of cocoa-butter and 3 c.c. of olive oil; the pasty mass so obtained is moulded into square-section rods or other formed bodies, or into sheets from which formed bodies are stamped.  When solidified the bodies are coated with the cocoa-butter-olive-oil mixture or petroleum jelly to exclude moisture.  The carrier is then made by dissolving 125 grams of gelatine in 200 c.c. of warm aqueous solution of mercuric cyanate of strength 1 : 10,000, to which 5 grams of egg albumen may have been added; the following ingredients are then added, aluminium aceto tartrate, 20,grams, hexyl resorcinol, 100 c.c. of 1 : 1000 solution, kalada juice, 100 c.c., glycerine 350 c.c.  The carrier may be rendered opaque by whipping air into it or adding an opacifying substance.  The suppository is moulded in a two-part mould, the lower half of which is first almost filled with jelly carrier upon which after setting a rod or the like of gas-forming material is laid.  The mould is then closed and filled with jelly carrier in a vertical position.
