Abstract: 1368514 Controlling presses VERSON ALLSTEEL PRESS CO 8 March 1972 [22 March 1971] 10801/72 Heading B3H [Also in Division B5] A metal working press has the movement of its ram controlled electrically by an operator control station 63a<SP>1</SP>, Fig. 4, with stop and start push-buttons connected to an electrical socket 62 on the press frame through a connector duplicating unit 63a. The duplicator unit 63a provides one or more outlet sockets 73 to which one or more control stations 63a<SP>1</SP> can be connected. The duplicator unit 63a has press stop and start push-buttons PB1, PB2, PB3 similar to those of the control station 63a<SP>1</SP> and its circuitry is such as to connect the switches in series. The control station 63a<SP>1</SP> may be a circuit terminal unit, i.e. have no output socket, or, as shown, have an outlet socket 73. In order to terminate the circuit a dummy unit 75 is used in the outlet socket. If anly one control station is needed then the dummy unit 75 may be plugged into the outlet socket 73 of the duplicating unit, Fig. 3. The duplicating unit has sixteen contacts in its connections and these contacts engage corresponding contacts in the press socket, Fig. 4A (not shown). The control stations have similarly arranged contacts as also has the dummy unit, however, as a safety measure, the dummy unit does not have a jumper connection between connections (2), (2<SP>1</SP>) to prevent operation of the press if the dummy is inserted directly into the press socket 62. The control stations can be arranged at spaced positions around the press although only one socket 62 is provided. Further by using the duplicating unit any number of stations can be provided. The circuits of the stations are connected in series so that the press only operates when all the start buttons are pressed. There are two start buttons at each station to prevent accidental operation of the press. The press socket is connected to solenoids of a clutch brake assembly of the press which may be arranged for continuous, single or inch operation.

Abstract: 1450990 Controlling dimensions of extruded foam SOC CHIMIQUE DES CHARBONNAGES 13 March 1974 [16 March 1973] 11252/74 Heading B5A [Also in Division C3] A thermoplastic polymer containing a foaming agent, is extruded to foam upon issuing from an extrusion die and, at the exit of the die, is differentially cooled around its periphery by fluid pressure jets to effect expansion differentially to a shape at least similar to that of the shape of a sizing die through which it passes, so that friction is reduced in drawing the shape through the sizing die. The sized shape is cooled in passage through water tanks. The fluid may comprise cold compressed air, e.g. at 20 C., or other gas, or a suspension of water in air. The differential cooling may be effected by differing pressure and/or temperature of the fluid. In Example (1), the polymer comprises high impact polystyrene containing polybutadiene foamed with zeolite, the extrusion die shape 1 being as shown in Fig. 3, or in Fig. 1 (not shown), and the sizing die shape being as shown in Fig. 2. The fluid cooling is effected by two (or four or eight) compressed air or water suspension blowing devices 3 and 4, each comprising one or more orifices, with the upper device 3 operating at a higher pressure than the lower device 4. Figs. 5 and 6 (not shown) show variations of shape effected by varying the fluid pressures. In Example (2), a similar high impact polystyrene foamed with azodicarbonamide is extruded from the Fig. 7 die shape, to produce a rectilinear sided "L"-section, the cooling fluid being directed at different pressures from three locations across the top of the extruded section, and locations at either side and at the bottom of the section. In Examples (3) and (4), crystal polystyrene, or rigid P.V.C., containing azodicarbonamide is extruded from the die 1a of Fig. 10, to produce a rectangular section, using upper and lower 3, 4, and opposite lateral fluid blowing devices operating at different pressures. Foam densities are stated. The differential cooling may produce a variable surface around the article comprising a smooth skin, a rough skin and/or the absence of a skin.

Title: Improvements in obtaining prophylactic and therapeutical vaccines
IPC: A61K39/00
Filed: 1954-04-23
Abstract: Process for obtaining a prophylactic or therapeutic vaccine against a specific disease is characterized by taking blood direct from a person or animal having the disease, diluting it with an isotonic liquid to a concentration of from 1 in 30 to 1 in 1000, and destroying or attenuating the virulence of the pathogenic agents by physical, chemical or biological means, there being no cultivation of the active principle of the vaccine in an artifical medium.  The dilution may be carried out with physiological saline.  In preparing a prophylactic vaccine against "polio" blood is taken from a monkey convalescing from the disease, diuted with physiological saline and the coloured constituents removed. The so-formed serum is irradiated with ultra-violet light and placed in a sterile bottle.  A second monkey is inoculated with the same virus as the first, and venous blood removed during the fever period.  This is diluted with saline. 25 per cent of the total volume is further diluted with physiological saline and exposed to ultra-violet light, and bottled.  A second 25 per cent is mixed with the treated serum from the first animal and the remainder is diluted with physiological saline.  The three preparations are injected according to a special schedule described in the Specification.  For oral administration the preparations may be enclosed in suitable enteric capsules.  The preparation of a therapeutic vaccine against undulant fever is described.
