Title: Contact free measurement for ground work - uses surface reflected laser light converted into electrical signal and fed to comparator
Inventor: BAASEL CARL FERDINAND
IPC: G01B11/00
Filed: 1977-01-10
Abstract: The contact-free measurement is for grinding edges and grinding angle of materials which are worked on grinding machines. The machined materials are measured optically by observing the tight reflected from the material surface, which is reflected in different directions according to the inclination of the ground or unground surface. The measurement can take place continuously during the grinding process. The measurement can be carried out on moving material. The reflected light is picked up by an optical detector and is converted into an electrical signal. The electrical signal, as a parameter of the measured valve, is compared with a given valve and the comparison valve is fed to an evaluation device.

Title: High temp. insulating foam mfr. - by foaming reinforcing fibre, bentonite, expanded aggregate mixt., shaping, drying and firing at low temp.
Inventor: ERSKINE CLIVE ARNOLD
IPC: C04B33/00
Filed: 1977-02-28
Abstract: A high temp. insulating foam is made by (a) mixing 0.5-20 (pref. 1-5) wt.% reinforcing fibre (pref. E glass fibre), 40-95 (pref. 70-85) wt.% expanded aggregate (pref. expanded perlite) and 5-40 wt.% bentonite, with sufficient water to form a gellable foam; (b) foaming the mixt., then shaping and drying the foam; and (c) firing the foam at 900 degrees C but above the temp. at which bentonite lattice hydroxyl water is lost (pref. 650-850 degrees C, esp. 680-720 degrees C). The insulating materials can be used at =850 degrees C and compare favourable with conventional Ca silicate insulation. It has lower shrinkage and reduced dust liberation than Ca silicate, and it does not degrade at its operating temp. The process gives a 'foamed foam' structure giving better wt. and insulating properties. It does not collapse during drying even though it does not set and does not include a setting agent.

Title: Cyclone furnace with forced gas circulation - has partitions splitting hot gas stream into independently controlled side streams
Inventor: MIRONOV VIKTOR L
IPC: C03B25/06
Filed: 1977-03-23
Abstract: A cyclone furnace with forced gas circulation for use in the metallurgical and glass industry has in the delivery circuit of the gas circulating device a number of partitions which divide the hot gas stream in several side streams. These are directed on the products and include in their path independent heat controllers such as heat exchangers, butterly valves or gate valves.

Title: Heat recovery system for air separation - having regenerators with side stream to heat exchanger to ensure full heat recovery
Inventor: ROHDE WILHELM
IPC: F25J5/00
Filed: 1977-08-03
Abstract: Low temp. separation of air uses >=1 interchangeable pair of regenerators which are used to exchange heat between part of the incoming air feed stream and part of the separated product, allowing impurities to condense out. A second portion of the feed stream is purified by adsorption and is cooled by a second product stream in a heat exchanger. Both air streams are combined and fed to the separation process. A side stream is taken from the generator before the heat exchange process is completed and fed into the heat exchanger at an intermediate position. The side stream is heated in the exchanger and then mixed with the air stream flowing to the adsorber system. It can also be a product stream. Improves the thermal efficiency of such systems by recovering the excess heat caused by an imbalance of flow without resoring to expensive equipment.

Title: Gravity mixing esp. of plastics granulate in silo - by initial central discharge followed by peripheral discharges and recycling to top of silo
Inventor: HILGRAF PETER
IPC: B01F5/24
Filed: 1978-01-27
Abstract: A method of gravity mixing of powdery to granular material stored in a comparatively slender vessel or silo, consists of discharging the material from the bottom of the silo and recycling it to the top in a specific sequence. In a first stage, the entire quantity to be recycled is discharged from the tapering bottom of the silo via a central pipe and is recycled to the top. During succeeding stages, the entire quantity to be cycled is drawn from the bottom of the silo via a number of discharge pipes and also simultaneously from the central pipe. All the pipes are of equal cross-section. Pref., in the second and all subsequent stages the material is drawn partic. from the tapering hopper bottom of the silo. Esp. for mixing stored plastics powder or granules. It is found that when the silo bottom is first opened and discharge is permitted through the central pipe, this produces a 'chimney' effect in the silo which effectively draws off material from all levels up to the top. In this way different sizes at different levels become thoroughly mixed during the first stage.

Title: Animal birth aid for calving - has tension lever responsive to overload instead of rigid to avoid injury
Inventor: UHLMANN GEORG
IPC: A61D1/08
Filed: 1978-04-29
Abstract: The animal birth aid appts. for e.g. a calf has a device bearing against the body of the mother animal, with two hooks on a tube alternately sliding and locking to allow continuous traction on the leg loops of the young animal.
