Patent DE-4141071-A1 (DE)
Title: Stamping tool for perforated ceramic substrates - perforations produced by pin in head plate of press and waste removed by pressurised air feed
Inventor: VOELKL FRANZ
IPC: B28D5/04
Filed: 1991-12-13
Abstract: The stamping tool consists of a foot plate (14), a head plate (5) and a mounting plate (6) which is recessed (21) to hold the cutting frame. A stamping section (13) is located on the footplate and surrounded by a spring-loaded (19) holding plate. Within the mounting plate is a pin,(8) which cuts a perforation when the press is operated. A compressed air feed (19) causes the cut waste material (23) to exit via a channel (20) in the foot plate. The pin head may be shaped to form an inclined entry as opposed to a vertical cut. USE/ADVANTAGE - Perforations can be cut in material which is still green and perforations formed with angled entry.

Patent DE-4204973-A1 (DE)
Inventor: MASBERG ULLRICH DR ING
IPC: B29C45/14
Filed: 1992-02-19
Abstract: The invention concerns a process for manufacturing an elastic rubber universal joint mounted between the flanges of two shafts with a common axis. A rubber universal joint of this type has at least three rigid sleeves mounted concentrically for the attachment on each of the two shaft flanges and has several other rigid parts, for example stop disks. The sleeves are connected to each other by elastic means. Both the sleeves and the elastic means connecting them are embedded in an elastomeric material. The elastic rubber universal joint is manufactured by direct combination as follows. First a plastic skeleton incorporating the sleeves and the several other rigid parts is made by an injection moulding device. Rubber is then injected around the plastic skeleton. The rubber is then vulcanized.

Title: Coast erosion protection bodies - are designed to trap sand or mud and consist of concrete feet with brushwood anchored to bottom
Inventor: ZANKE ULRICH PROF DR ING
IPC: E02B3/04
Filed: 1992-03-05
Abstract: The elements are for collection of sand or other sediments. This prevents or reduces sand movements, esp. erosion, in beach or coastal zones subjected to strong water currents. Concrete feet (6) are placed on the bottom of endangered waters. The feet have brushwood, trees, or similar natural or artificial material, fastened to them to give resistance against the current. The brushwood is securely anchored, and irremovable. The concrete feet have apertures, for anchor posts, for fastening in the bottom. USE/ADVANTAGE - The concrete and brushwood elements create regions of slow water flow, resulting in trapping of mud and sand, and build-up of sediments on the bottom instead of erosion.

Patent DE-4208275-A1 (DE)
Inventor: ANTRANIKIAN GARABED PROF DR
IPC: A23J3/04
Filed: 1992-03-13
Abstract: The invention relates to a strain W micro-organism with proteolytical properties, an enzyme composition obtainable therefrom, the use of the micro-organism and a process for hydrolysis, especially of keratin. The micro-organism grows anaerobically thermophilically and allows use of keratin-containing substances, e.g. feathers, as the substrate. The enzymes given off by the micro-organism into the medium or localised on or in the micro-organism are capable or dissolving keratin-containing substances like feathers, hair or horn within a few days and are active between 50 and 105  DEG C and at a pH of between 4 and 12. The enzymatic hydrolysis of peptides, especially keratin-containing substances, is conducted at a temperature  >/=  70  DEG C and anaerobically; decomposition can also be conducted at a pH 11 and at high temperature. The quantity of enzymes and other conditions can be selected so that the keratin-containing substrate is dissolved completely after 3 hours at the earliest and to the extent of at least 50 wt % after 24 hours. The enzyme composition and the process are especially suitable for the decomposition of feathers into oligopeptides or individual amino-acids.
Patent DE-4208666-A1 (DE)
Title: Bottle-sealing system using cap with skirt - thrusts cap in cylindrical casing over bottle head and crimps against neck by concave annular face in casing
Inventor: SCHOTT HELMUT
IPC: B67B3/14
Filed: 1992-03-18
Abstract: The system seals a bottle with flanged head from which a flank slopes towards the neck. The cap (11) with skirt (13) is accommodated in a cylindrical casing (20) which is moved over the head in the axial direction. A concave annular face (23) in the casing crimps the skirt end (15) simultaneously in a ring under the flank of the bottle head (2). In the final phase of the axial movement axial pressure can be exerted on the cap and which is absorbed by the bottle (1). The latter rests on a support, and protrudes through the annular rib at the casing end without coming into contact with it. USE/ADVANTAGE - Very little wear on cap when fitting, being particularly for bottles of pharmaceuticals.

Title: Two=stage series roller and ball milling process using a common sieve - where sepn. of finished prod. from 1st and 2nd milling stages occurs in common sieving operation, e.g. for milling cement clinker
Inventor: ASMUS REINHARD DR ING
IPC: B02C23/12
Filed: 1992-07-25
Abstract: Process for size reduction of mill feed, preferably cement clinker, in which the reduction proceeds in several stages, and pref. in two stages.

It is novel in that the separation of finished product from the first and second milling stages occurs in a common sieving operation, where the sieve is fed finished product from the first milling stage by pneumatic transfer, and final product mechanically from the second milling stage. USE/ADVANTAGE - Milling of cement clinker. Reduced capital cost and energy consumption by use of a common sieve and, air handling system, and prevention of inefficient recycling of fines through the roller mill.

Title: Metering of fuel into pre-combustion and main combustion chambers of a portable liquid fuel-driven apparatus
Inventor: GSCHWEND HANS
IPC: B25C1/08
Filed: 1992-12-22
Abstract: A small hollowed-out space in the housing (14) is used as a fuel evaporation space for a liquid gas cylinder (33) with valve (32).
