Patent DE-2453796-A1 (DE)
Title: Two temperature refrigerator with thermally insulated housing - housing rests on base frame containing compressor cooling assembly
Inventor: BALLARIN JUERGEN
IPC: F25D17/08
Filed: 1974-11-13
Abstract: Refrigerator, especially a two-temperature refrigerator with a housing thermally insulated by synthetic hard foam, which rests on a base frame which accepts a compressor cooling assembly with its heat exchangers. From this frame cooled air is fed via channels into the walls of the housing and is circulated in the refrigerator chamber. The housing (10) is assembled from wall elements (16, 17), which are in the form of sections of connecting plates manufactured in a continuous foaming process. The back wall (16) of these plates has one or more, longitudinal channels (15). The channel runs very closely behind a surface cladding (20) which forms the inside of the wall element (16, 17).
Patent DE-2460172-A1 (DE)
Title: Tubular heater with liquid-tight terminals - has metal tube and heating wire embedded in ceramic insulating powder
IPC: H05B3/48
Filed: 1974-12-19
Abstract: The heating wire ends are provided with terminal pins, and the insulating powder is compressed by reducing the sheath cross-section. Heating wire (2) terminal pins (3) are completely inside the sheath (1), at a distance from its ends, and are connected to power supply cables (9). The heating wire together with terminal joins are thus fully protected against mechanical stresses, especially bending forces. Since the heater tube end openings are reduced in size an annealing process serves for sealing purposes, thereby protecting the lead-in insulation. The mounting of the lead-in cable is simplified in that its length has to be decided upon after the reducing process.
Patent DE-2500348-A1 (DE)
Title: Paper sheet folder blade - has two or more laminations stepped back towards blade rear edge
Inventor: STREUBEL JOACHIM
IPC: B65H45/18
Filed: 1975-01-07
Abstract: The flat blade is carried in one or more holders, and is equipped with two or more laminations. These can be stepped back towards the blade rear edge, and some or all can be preloaded. They and the main blade can be interchangeably mounted on the holders, being joined to them by one or more elastic components. The desing gives safe and reliable operation over a long period, combining solid construction with depth of penetration and a high degree of elasticity, thus reducing the risk of permanent distortion in the event of jamming.

Patent DE-2532149-A1 (DE)
Inventor: BOSSEN DOUGLAS CRAIG
IPC: G06F12/16
Filed: 1975-07-18
Abstract: This specification describes an error correction system for a high density memory made up of a number of monolithic wafers each containing a plurality of arrays that are addressed thru circuitry and wiring contained on that wafer. The storage bits on the wafers are functionally divided into a number of blocks each containing a plurality of words. The words of each block are on several wafers with each word made up of a plurality of arrays on a single array wafer. Each word in a block is protected by a similar error correction double multiple error detection code. The block is further protected by two additional check words made up using a b-adjacent code. Each byte in the check words protects one byte position of the words of the block. When a single error is detected in any word by the SEC-MED code the code corrects the error. If a multiple error is detected, the multiple error signal points to the word in error to be corrected by the b-adjacent code check words.

Title: Dyeing textile by passage around roll with transfer sheet - and applying vacuum so dye transfers to textile from transfer sheet
Inventor: LOPATA KARL PETER
IPC: B41F16/02
Filed: 1975-09-01
Abstract: A continuous textile is dyed by passage around a roll sandwiched between a transfer sheet carrying a dye and a presser belt. The roller is heated and a suction is applied so that the dye transfers by sublimation from the transfer sheet to the textile. The suction is applied to a suction chamber which is pressed against the roller and which is hermetically sealed against the presser belt passing around the roll. The arrangement is cheap to produce and allows a constant vacuum to be applied, thereby ensuring uniform transfer of the dye.

Title: Polyether-polyester block copolymer prepn. - in the presence of a chloro-sulphonic acid catalyst
Inventor: BLAHAK JOHANNES DR
IPC: C08G63/66
Filed: 1975-10-03
Abstract: Polyether-polyester block copolymers with terminal -OH gps. are prepd. by condensing polyethers (I) and polyesters (II) in the presence of a catalytic amt. of chlorosulphonic acid. opt. in mixt. with sulphuric acid, at 200-250 degrees C The catalyst is a specific etherification catalyst which suppresses elimination of the terminal -OH gps. and formation of olefin gps. and prevents decomposition of polyhydroxy cpds. Discoloured oxidn. prods. are not formed. Catalytic activity is also greater. The prods. may be used to prepare polyurethanes having excellent low temp. properties, which may be used e.g. as elastomers, adhesives, foams and migration resistant placiticers for P.V.C. In an example, an adipic acid-diethylene glycol polyester with terminal -OH- gps. and polyetetramethylene glycol were dehydrated and reacted with chlorosulphonic acid to give a block copolymer.

Title: Drag control for fixed pitch marine blade - with welded seams in pattern on front and back of blade
Inventor: OKAMOTO HIROSHI
IPC: B63H/
Filed: 1975-11-07
Abstract: The front (4) and back side (5) of the marine screw blade are warmed by localised heating and have a pattern of weld seams applied, proud of the surface. This alters the inclination of the tip of the blade (3) to tune the blade drag to the optimum engine speed. Weld seams on the back (5) tend to flatten the pitch, while seams at the front increase the pitch. the weld seams are smoothed off by simple machining to allow the blade to be used effectively. The process alters the blade pitch to suit the hull drag as the ship ages.

Title: Tapered cross spool winding machine - has diversion point in buffer unit controllable to accommodate additional thread
Inventor: RAASCH HANS
IPC: B65H59/34
Filed: 1976-03-11
Abstract: The winding machine is for tapered crossed spools. Thread is delivered to teh spool at constant speed, using a controlled buffer unit with three thread diversion points forming a loop, and a reciprocating thread guide. One of these three points is controllable to accommodate an additional quantity in the buffer unit. The alternating angle of the run of thread between unit and guide counteracts the variation in tension occurring during the winding operation. The drive to the point concerned can be taken via a cam, or a drive linkage giving the same effect, from the drive to the buffer unit.
