Title: Integrated circuit with MIS semiconductor elements - is produced by deposition of insulating and photolacquer films followed by exposure and etching
Inventor: WIDMANN DIETRICH DR
IPC: H01L29/06
Filed: 1976-09-14
Abstract: In the production an insulating layer is deposited on a semiconductor substrate, and consists of individual gate regions and field insulating layers surrounding the same. The regions underneath the insulating layer are doped by ion implantation near the surface, using a mask on the field insulating layer. First an insulating layer (2) having a thickness of the field insulating layer is deposited on the semiconductor substrate (1). The insulating layer is coated with a photo-lacquer film (3). The latter is exposed through a mask and developed with the result that the lacquer is removed from regions intended for the gate regions (4). These regions of the insulating layer are then removed by etching. After vapour deposition of a masking layer the remaining regions (6) of the lacquer film are removed after which the ion implantation takes place.

Title: Feed conveyor control system - has sensors to stop feed during delivery of items from discharge or transfer station
Inventor: LISCHKA DIETMAR
IPC: B65G43/08
Filed: 1976-10-05
Abstract: The system controls the operation of a feed conveyor supplying discharge and transfer stations. The items are delivered until the discharge station is full. The conveyor forming the discharge station and/or the feed conveyor, are then stopped and simultaneously the discharge or transfer operation is initiated. When the station is free again, supply from the feed conveyor is restarted to deliver a number of items slightly greater then that needed for the transfer or discharge operation. The feed conveyor can have a first feeler (7) shortly before the discharge station, working in conjunction with one or more further feelers (5, 6) in the station (2, 3).

Inventor: SCHEUERPFLUG HANS ING GRAD
IPC: B60K17/04
Filed: 1976-10-26
Abstract: The high-speed mobile caane has a superstructure with jib and drive units slewing on a travel chassis, together with a first engine in the chasssis for high-speed travel and a second one in the superstructure driving a pump to supply the hydraulic motors for the various crane motions.

Patent DE-2708100-A1 (DE)
Inventor: MURBACH JULES
IPC: F16L3/14
Filed: 1977-02-25
Abstract: The suspension device is used for the length-adjustable suspension of a carrying strap which is releasably held in a fastening bow. On the carrying strap there may be suspended, for example, pipes or rails which have to be guided along a ceiling in a building. In order to simplify the construction, the clamping device (22, 23) of the fastening bow (4) has at least one guide surface for the flexible carrying strap (10). Said guide surface is inclined relative to the base part (12) such that the carrying strap (10), running out of the clamping device, is directed to an edge region (3) of the base part (12) or beyond. In order to grip the carrying strap (10), the flange part (14, 16) of the fastening bow (4) has a cutout (34, 36), in the region of the edge which is common both to it and to the base part (12), in order to be able to bend off a projecting end portion of the carrying strap (10) in a reliable fashion. Furthermore, there are extensions (43) for fastening the suspension device in a C-profile rail.

Patent DE-2716520-A1 (DE)
Title: Look ahead controls for address translation operation - provides look ahead feature when segmentation registers are loaded to reduce time needed to select memory units to be accessed
Inventor: BIRNEY RICHARD EUGENE
IPC: G06F12/02
Filed: 1977-04-14
Abstract: The look ahead circuits are for an address relocation translator which contains stacks of segmentation registers (SR's), each of which may be loaded with an assigned address of a physical block in a main memory. An additional pair of bit positions are provided with each SR to receive look ahead bits from decoder loading circuits which decode a physical address being loaded into the SR to indicate the storage unit containing the addressed block. During each subsequent address translation the loaded look ahead bits are outgated while the block address is being read from an SR. The look ahead bits are decoded for selecting the required storage unit component of the main memory, and a translator interface is switched to that unit. The look ahead bits are handled by parallel high speed circuits so that the required storage unit is selected before a storage unit cycle is generated by the translator for accessing the addressed block.

Title: Refractory lining for metallurgical reactors - is protected against slag attack by curtain of inert gas
Inventor: FRANKE ERNST PETER PROF DIPL I
IPC: F27D1/16
Filed: 1977-06-16
Abstract: A new system is described for reducing the wear of refractory linings in metallurgical reactors and ladles and for weakening the high aggressivity of the slags, which is aggregated by the high temp. Inert gases are introduced to rise in front of the refractory lining so that the contact area between slag and refractory lining is diminished and the temp. of the contents in the peripheral zone is kept low. This also keeps temp. fluctuations away from the refractory lining.

Title: Photopolymerisable compsns. for printing plates etc. - contain polymerisable monomer, polymeric binder, photoinitiator and etherified thio-anthraquinone cpd.
Inventor: BRONSTERT BERND DIPL CHEM DR
IPC: G03F7/031
Filed: 1977-12-31
Abstract: The compsns. contain (a) >=1 cpd. of low mol. wt. and contg. >=1 unsatd. photopolymerisable double bond; (b) >=1 compatible organic polymeric binder; (c) a photo-initiator; and (d) 0.001-0.1 wt. % of an etherified thioanthraquinone cpd. of formula (I):- in which R is 1-12C alkyl, 1-8C alkyl substd. by an opt. etherified and/or esterified OH gp. and/or an alkoxycarbonyl gp., or an opt. substd. phenyl gp. Pref. cpds. (I) are propyl-, n-butyl-, and isobutylthioanthraquinones, and esp. 2-butylthio-2-anthraquinone (II). Presence of the (I) in known photopolymerisable compsns. reduces undesired polymerisation of the compsn. in the shadow of fine opaque image elements during exposure in contact with a negative, thus giving improved image clarity. The presence of the (I) does not reduce the light sensitivity or exposure latitude of the material.

Title: Oriented lignocellulose fibrous mat mfr. - a current being passed through the mat to create an orienting field directly above it
Inventor: TALBOTT JOHN W
IPC: B27N3/14
Filed: 1978-08-09
Abstract: In a process in which elongated or flat lignocellulose particles are directed onto a moving belt through an orienting field provided by electrodes spaced above the belt, a current is passed through the thus deposited mat in the direction of belt movement. The current causes an electric field parallel to the belt to be set up between the bottom of the electrodes and the mat and thus ensures that the particles are deposited with their orientation in a plane parallel to the belt. In prior art devices using only electrodes, the field between the mat and the bottom of the electrodes was non-uniform and caused misorientation of the particles.
