Patent DE-2636951-A1 (DE)
Title: Degrading starch or starch derivs. in paper prodn. - by treating with amylase to reduce viscosity and simplify coating process
Inventor: KUNKEL ERNST
IPC: C01B31/00
Filed: 1976-08-17
Abstract: Amylases are used to degrade starch (derivs.) used in paper prodn. By partial degradation, the viscosity can be controlled to a desired value and the coating process simplified. For example, an aq. 7.5% soln. of a starch ether (e.g. 'Solvitose H') has a viscosity of 35 cP and pH 6.5. By adding 0.05% of an alpha-amylase (e.g. 'Biolase PC 90') the viscosity is reduced, the process being stopped by adjusting the pH to 3.5. This can be carried out, e.g. by adding acetic acid. The viscosity can be adjusted to any value between 35 and 2 cP, by varying temp., enzyme concn. and time.

Title: Gusseted plastic bags mfd. by sealing tubular film - by locally staggering the welding seams in the gusset region to increase of load carrying strength of bags
Inventor: KLINK GEORG
IPC: B29C65/22
Filed: 1976-12-31
Abstract: Sacks or bags with side gussets are mfd. from tubular film and heat-sealed. In the region of the gussets where the film passes from a 2-ply into a 4-ply structure the welding seam is arranged, in staggered fashion, by twice changing its direction by an angle of 20-40 degrees and by an amt. of >=2 seam widths. The film is cooled near the seam zone, to below the m.p. of the film, during the sealing step. Bags with gusset depth of 100m were welded from H.P. polyethylene tubular film, 200 m mu thick. The heating band was off bent by an angle of 30 degrees and stretched to the width of the bag. Starting temp. was 70 degrees C, finishing temp. 280 degrees C. Welding cycle was 1.2 sec., sealing-jaw closing cycle 3.8 sec.. Cooling was by gas under 0.8 bar at 20 degrees C, in the seam region. The resulting seam was uniform and its breaking and impact strength exceeded that of the film. Load bearing strength of the bag is considerably increased.

In the formula R is CO2R3 or H; R2 is H whe R' is -CO2R3; or R' is -CO2R3 when R' is H; R3 is H or an aliphatic group; X is halo; R4 is an aliphatic or aromatic group; Y is halo, the group OR3 or a group -O3S.R4. Provides simple, more economic process for prodn. of (I) which is intermediate for thiophen-saccharin sweetening agents. A typical cpd. methyl-3-chlorosulphonylthiophen-4-carboxylate, was prepd. by the 4-stage process from methyl 3-hydroxy-dihydrothiophen-4-carboxylate.

Title: Lift system spring buffer - has coil spring ends coupled to piston and cylinder of one:way hydraulic damper to prevent rapid spring expansion
Inventor: NAGEL HEINZ-DIETER
IPC: B66B5/28
Filed: 1977-03-18
Abstract: The lift spring buffer has a coil spring fixed to a base in the lift shaft. One end of the spring (3) is coupled to the piston (4) and the other end to the cylinder (5) of a one-way hydraulic damper (6), ineffective when the spring is being compressed. The space (8) above the piston is connected by an adjustable jet (9), followed by a valve (10) opening only as the spring expands, to that (11) below. The design prevents spring expansion occurring too rapidly, with the consequent risk of injury for the lift passengers.

Title: Cathodic protection of very long underground pipelines - via numerous electric circuits with synchronised electronic controllers
Inventor: LYSS HARTMUT ING GRAD
IPC: C23F13/04
Filed: 1977-05-17
Abstract: Circuits (E) which supply electric current for the cathodic protection against corrosion of an underground pipeline, are simultaneously switched off so the potential (P1) between the pipe and the ground can be measure. One circuit is fitted with a controller contg. a clock generator started by hand and used to switch the circuit off to measure P1. All the other circuits have a controller contg. a timer operated simultaneously with the generator for measuring P1. Timers switch the current off for a specified time; and the resulting drop in P1 is used in an evaluation circuit to provide a pulse which switches the currents on again. Each controller pref. includes a measuring probe connected to circuit which is followed by a gate circuit, the timer and then an amplifier which includes an electronic switch. For example, a pipeline several hundred km long is fitted with numerous circuits switched on for 27 seconds then off for 3 seconds to measure P1.

Title: Valve with spherical closure member - has non-return valve fitted in passage through spherical member in normal spherical seating
Inventor: JANSSEN-WEETS PETER
IPC: F16K5/06
Filed: 1977-06-14
Abstract: A valve is used which has a spherical closure member (1) supported for rotation in a housing (10) about a diametral axis of the member. During such rotation a diametral passage (1a) of the member can be aligned with the flow passage of the housing. The passage of the member contains a non-return valve (1b) so that flow through the passage is possible in one direction only.

Title: Shot gun hammer safety mechanism - has handle-actuated lever for slackening hammer spring with lock operated by wedge and push rod
Inventor: GSAENGER DIETER
IPC: F41A17/20

Title: Deaerator for emulsions and pastes - with nozzle plate and adjustable grating with spikes
Inventor: DOERNBRACK GUENTER
IPC: B01F15/00
Filed: 1978-05-11
Abstract: A device to deserate emulsions, mixts. and pastes in the food and pharmaceutical industry was described in Patent No. 1 190 438. Downstream of a plate with outlet nozzles which terminates the domed inlet distributor housing, a grating with passages carries spikes which face the flow direction and have a roughened or rippled surface. This removes the last remnants of air bubble inclusions from the fluid which are then removed by a vacuum. Growth promotion by the oxygen in air bubbles is thus prevented and a better sterility ensured.
