Title: Childproof screw top container - for conventional bottles with ratchet teeth on ring insert outside and top side
Inventor: HAZARD ROBERT E
IPC: B65D55/12
Filed: 1976-08-12
Abstract: A container is made childproof by an annular insert with inside teeth which act against the collar on the neck, and with outside ratchet teeth which act against ratchet teeth on the cap. The cap can thus be screwed down but is normally prevented from unscrewing by the ratchet action. The pref. material for the container is a soft plastic, suitable for blow moulding, such as polyethylene. The pref. material for the insert is a harder plastic, suitable for injection moulding, such as polypropylene. This system can be applied to all conventional containers and bottles and saves expensive changes of tooling and dies.

Title: Distn. process with variable reflux - having vapour removal from enrichment zone to heaters in stripping zone
Inventor: HASELDEN GEOFFREY GORDON
IPC: F25J3/00
Filed: 1976-08-26
Abstract: Sepn. of mixts. is carried out in two stage process by distn. At least part of the vapour generated in the enrichment zone is removed and condensed inside heaters located in the stripping zone. This has the effect of increasing the reflux in the enrichment zone and at the same time increasing the vapour flow in the stripping zone. The enrichment or first zone operates at a higher pressure than the stripping or second zone. This second zone should be at a higher geodetic level than the first to allow gravity return of condensed liq. In practice a pair of columns is used with vapour extrn. from between trays on the first and heat exchange coils on the trays in the second. Provides improved sepn. for reduced energy consumption esp. in cryogenic systems.

Title: Power operated vending device - has motor with cam operated switch and cam disc operated switch and torque limiting coupling
Inventor: LEVASSEUR JOSEPH LEO
IPC: A47F3/024
Filed: 1976-10-06
Abstract: A vending device has a power supply, motor, cam operated switch, a cam disc operated witch and a torque limiting coupling. The motor (11) drives the load and a cam (14). The two switches (16, 17) are positioned between the power supply and the motor (11). The cam disc (21) supports the load and is coupled via the coupling. The cam disc (21) switches off the motor (11). If the predetermined torque is exceeded, the coupling allows movement of the cam (14) relative to the cam disc (21). Thus the cam operated switch (16) applies the power supply to the motor (11) and the cam disc operated switch (17) switches off the motor (11).

Title: Electrophoretic sepn. of protein - with introduction of protein into carrier gel as mixt. with dextran swollen with sucrose soln.
Inventor: BISSBORT SIEGBERT
IPC: G01N27/447
Filed: 1977-02-01
Abstract: In a new procedure for the electrophoretic examination of proteins (enzymes, serum proteins, tissue, homogenates) involving introduction of the proteins by means of a carrier medium into holes in a flat layer of carrier gel (agar, starch or polyacrylamide gel), there is used as the carrier medium a swollen gel (preF. with a low degree of crosslinking) in the form of dextran swollen with water or buffer soln. with the addition of sucrose. Use of sucrose-contg. dextran gel as carrier medium enables protein to be applied to the carrie medium by simple pipetting. the sucrose stabilises the proteins against damage while passing through the dextran. Larger amts. of protein can be used than with known methods, and even minor proteins (e.g. human erythrocyte phospho-glucomutase isoenzyme 3) can be detected.
Patent DE-2706745-A1 (DE)
Title: Turbine flow rate measurement device - uses short narrow plane blades for laminar flow error reduction
Inventor: HIEKE WILLIBALD DIPL ING
IPC: G01F1/12
Filed: 1977-02-17

Patent DE-2852659-A1 (DE)
Inventor: STADLER JOERG DR
IPC: B21D22/14
Filed: 1978-12-06
Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through cold pressure rolling. The spheres are arranged in the interspace between a basic support member, which may be a thin-walled inner casing, and an outer casing. Forging of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thin-walled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.
