Inventor: GRUND CHRISTIAN ING GRAD
IPC: F24H1/26
Filed: 1977-03-21
Abstract: The heating system boiler is fired with liq. or gas fuel. The boiler cylindrical shell is enclosed by an external shell forming an annular water jacket. The combustion chamber at one boiler end is partitioned by a transverse wall from the flue gas outlet chamber. flue gases flow along the longitudinal channels between jacket inner wall and partition cylindrical wall.

Title: Two pole light emitting semiconductor module - radiates light without obstruction by lateral arrangement of all contacts
Inventor: BUGGE FRANK DIPL ING
IPC: H01L33/00
Filed: 1977-03-22
Abstract: The device has two highly doped regions of the p- and n-type, each with a semiconductor metal contact. A lower conductivity region joins them and a luminescent region surrounds one of them on sides and in depth. The luminscent region is straddled by a conductive strip, resting on a film with a high insulation resistance. This creates a light-emitting structure in which the charge carries balance in the semiconductor can be arranged so as to introduce the charge carriers into the luminescent region.
Patent DE-2713927-A1 (DE)
Inventor: HAUER WALTER
IPC: H02G1/12
Filed: 1977-03-29
Abstract: Machines for removing the sheathing from lead-sheathed cables, known as stripping machines, contain at least two adjustable blades through which the cable to be stripped is drawn. Since conductor cross-section and sheath thickness may deviate from their ideal values over the length of the cable and damage to the conductor is to be prevented, the spacing of the blades from one another must be adapted at least to the largest possible conductor cross-section. To avoid the resulting disadvantage that the cable sheath (19) is incompletely separated in areas with smaller conductor cross-sections, the blades (5) according to the invention are movably mounted in a guide (8) attached to the machine, perpendicular to the running direction of the cable (19, 21) and against the force of a spring (14). <IMAGE>

Title: Drying of adhesive applied to book pages during binding - is limited to three zones to prevent smearing of trimming blades
Inventor: EHLERMANN HANS DIPL ING
IPC: B42C9/00
Filed: 1977-06-03
Abstract: When binding pages of a book adhesive is applied to the edge (R) of the block of pages (10). When using an adhesive composed of a synthetic resin emulsion containing a suitable plasticiser sufficient time must be allowed for the adhesive to harden and it must not be dried too quickly. The page blocks are dried in three separate regions i.e. at each end (F) (K) and in the middle (M) where the edges of the block (10) are trimmed and the block cut in two. The block (10) is moved on a conveyor belt (11) of PTFE over radiant strip heating elements which limit the drying to the zones (TZ). Pref, the heat is produced by HF electromagnetic radiation or by IR radiation.

Patent DE-2807269-A1 (DE)
Title: Draw frame for textile fibres - has torque regulator comprising a re-engageable slip clutch (BR 26.12.78)
Inventor: KLEIN KONRAD
IPC: D01H13/14
Filed: 1978-02-21
Abstract: A draw frame for textiles comprises rollers of great length, connected by gear systems incorporating special interchangeable gears spaced at wide reciprocal intervals, and thus forming closed mechanical gearing units. The frame has a torque regulator interposed in each gearing unit which can transmit a max. torque moment B, complying with the relationship A B C, in which A is the max. torque produced during the normal functioning of the frame and C is the min. torque moment which may risk causing deterioration of the mechanism. These two valves are each built in at the site of fitment of the torque regulator. The torque regulator pref. comprises a slip clutch which is capable of being re-engaged, immediately after it is activated. In such drawing machiney, the rolles are driven by positive engagement of the gear systems. Where the relationship of speeds is required to be altered, certain gears have to be changed for others having a different number of teeth. It may happen than an operator, though oversight, may introduce gears with the same number of teeth, which could result in a deterioration of the gearing or of the roller pairs. In the event of such mistaken gear fitment, the torque regulator of the invention will stop the draw frame and send out a visible or audible signal to the operator.

Title: Pulsed power supply system - is for discharge equipment for treating workpieces and prevents glow discharge passing over into damaging arc discharge
Inventor: AIZENSTEIN ANATOLIJ GDALJEVITS
IPC: H01J37/32
Filed: 1978-04-13
Abstract: The power supply (100) for ion-nitriting and ion-coating equipment, produces pulses of variable frequency for applying to the glow-discharge path. The energy of each pulse is kept constant independently of the type of discharge and its parameters. The energy of each pulse is less than the minimum energy needed to cause an arc discharge -- which would damage the workpiece being treated. However, if an arc discharge does occur, the next pulse is delayed by a time interval greater than the de-ionising time of the discharge path.

Title: Solid propellant charge - contg. polymeric binder and reinforcing fibres, e.g. cellulosic fibres
Inventor: REDECKER KLAUS DR
IPC: F42B5/188
Filed: 1978-10-05
Abstract: Casing-free propellants are made contg. (a) a powdered propellant with a detonation point of >180 degrees C, (b) pref. 3-10 wt.% of a polymeric binder and (c) 0.1-10 wt.% fibres. Suitable fibres are e.g. natural and synthetic fibres such as cellulosic-, polyester-, polyamide-, polyolefin-, polyacrylic-, cellulose nitrate-, polyurethane-, glass-, and carbon fibres. The fibres increase the strength of the propellant charges whilst maintaining or improving the inherent ballistic properties of the charge. This is in contact to increasing the strength of the charge by increasing the binder content, which causes a deterioration in ballistic properties.
