Title: Motor vehicle aerodynamic spoiler - consists of inverted aerofoil generating downward thrust and held on roof, by brackets with clamping arms received in gutters
Inventor: REICHEL BERNHARD RAINER
IPC: B62D35/00
Filed: 1976-10-04
Abstract: The motor vehicle roof aerodynamic spoiler increases vehicle contact pressure on ground. The contact pressure is increased with increasing speed to ensure vehicle stability. The spoiler is clamped by luggage carrying clamps on the vehicle roof gutter. The ends of the transversely mounted spoiler profile have tubular projections (3).

Title: Two compartment water tank for solar heating system - is divided by fixed partition or flexible membrane, sealed all round
Inventor: JANSSEN HARALD DIPL ING DR
IPC: F28D20/00
Filed: 1977-05-28
Abstract: Instead of using two hot water tanks in e.g. a solar heating system, a single tank divided horizontally into two parts is used. A fixed plate (1) is supported at a required height by a sealing ring (8) around the interior. This forms a hot water section and a cold water section, each with its own connection (3, 5), so that the hot and cold water do not mix. In an alternative design, the fixed plate is replaced by a flexible membrane, which can be mounted low down, and which can bulge upwards into the upper region.

Title: Fuel injector for IC engine - has soft metal body with hard chrome layer on valve seat
Inventor: KUENZLER HANS DIPL ING
IPC: F02M53/04
Filed: 1977-06-07
Abstract: The injector bush (14) is clamped between the injector holder (12) and the nozzle cap (18) by a securing nut (16). Fuel enters through a passage (12a) in the holder and enters a chamber (14r) round the end of the spindle (22). Cooling water enters through a passage (12b) in the holder and flows into an annular space between the bush and the cap. The spindle (22) carries a valve cone (22s) which seats on the valve (14s) at the outlet of the bush (14). The nozzle cap (18) contains the injection orifice (18s). The valve bush is made of a soft metal and the valve seat (14s) is coated with a hard chrome layer. This provides the necessary hardness for the valve seat while retaining the advantages of a soft material for the bush.

Title: Changing program of PROM - by insertion of jump instruction leading to changed programme parts
Inventor: BRETTSCHNEIDER DIETER
IPC: H04Q3/545
Filed: 1977-11-25
Abstract: The stored programme, pref, for telecommunications exchange systems, is changed by forming the jump instruction by subsequent change of individual elements (E1-E24) of the instruction to be modified in the possible direction. The still unchanged operator (OR) of the instruction to be changed causes operation of the control device. This control device, thus controlled, in conjunction with the still unchanged operands (OD1, OD2 of the instruction, prevents further data processing. The operator of the instruction may consists of, a part from one element, changeable elements.
Patent DE-2801841-A1 (DE)
Title: Continuous catalytic conversion of hydrocarbon feed - with redn. and sulphiding of regenerated catalyst in zones sepd. from reactor (NL 24.7.78)
Inventor: BORET ROGER
IPC: B01J23/90
Filed: 1978-01-17
Abstract: In the continuous conversion of hydrocarbons in presence of a catalyst, a feed charge consisting of hydrocarbons and H2 is circulated through >=1 reaction zone of the moving bed type. The catalyst flows progressively downwards through this zone, is removed from the bottom part of the zone, and is fed to a regeneration zone. The regenerated catalyst is led through a redn. zone, at 480-530 degrees C which is charged with H2 and which is heated by a part of the charge or by the reaction effluent. The regenerated and reduced catalyst is passed from the redn. zone to the upper part of the reaction zone through several pipes which form a sulphurisation zone, separate from the redn. zone and the reaction zone, and the catalyst circulates as a mobile bed and is sulphided at a temp. below the temp. of redn. and reaction ie. at 300-400 degrees C (310-380 degrees C) by means of a gas contg. a S cpd. The temps. of sulphiding and redn. are lower than the reaction temp. and are easily controlled; sulphiding and redn. zones are heated independently of the first reactor. The redn. and sulphiding zones are sepd. from the reaction zone, thus reducing the danger of explosion, e.g. an explosion in the redn. zone is less likely to reach the reaction zone than in known processes.

The spindle works in two diametrically opposite bores of a duct, in which there is a semicircular slot symmetrical in relation to the first bore and connected to it, in which the butterfly is a clearance fit. Slot and bores are sealed on the outside of the tube, typically by means of a two-part pipe clip, with sealing material between it and tube.

Title: Linkage mechanism for radio tuning knob - has hollow cylinder with cam shaped end path insertable on tuner drive shaft with radial follower
Inventor: BRETTSCHNEIDER DIETER
IPC: H03J1/10
Filed: 1978-02-07
Abstract: The linkage mechanism connects a rotary tuning knob, or V-pulley rotated by cord, to a control component, such as a tuning capacitor, drive shaft. The turning knob (19) has a hollow cylinder (12) with a cam-shaped end (13) can be inserted onto the drive shaft, when the two housing parts are assembled. The shaft (3) has a radial follower element (6), long enough to engage the cam-shaped end. The hollow cylinder contains a coupling drive whose strip engages the drive shaft slit, which it forms a cross-coupling. The length of the slit, or the coupling drive position, ensures active position of the follower w.r.t. the cam-shaped cylinder part.
Patent DE-2807972-A1 (DE)
Title: Sprung stabiliser for trailer - is constructed with opposing springs on damping mass to reduce slewing oscillations
Inventor: FEND FRITZ M
IPC: B62D37/04
Filed: 1978-02-24
Abstract: The slewing stabiliser for the trailer or caravan has a transverse guide in which is mounted a special inertial mass supported between two opposing springs. The frequency of the mass is adjusted so that it counteracts the slewing frequency. The slewing frequency is nearly independent of trailer speed, with the axis of the guide parallel to the wheel axle. An adjuster at one end of the guide enables the stabiliser to be tuned to the trailer. A relatively small inertial mass can stabilise a heavy trailer.

Title: Paper making vacuum water extraction control - uses difference in two fluid levels with jet-delivered control fluid to correct level imbalance
Inventor: SONNTAG LEOPOLD
IPC: D21F1/48
Filed: 1978-04-05
Abstract: The vacuum control system for use in the mesh section of a paper making machine uses the difference in the levels of two fluids. The first fluid level has a float in the vessel to control the passage of air through a valve. The second fluid level has a flexible tube to register its condition, with a control vessel with height adjustment against the vessel with a float. An adjustable jet is provided for the float vessel to pass a control fluid continuously through to it. The system avoids passing through un-needed air and consequent disruptions.

Title: Tool for expanding metal pipe bore - uses hydraulic pressure exerted from inside flexible sleeve held by end caps within pipe
Inventor: AMEN RANDALL MARK
IPC: B21D39/20
Filed: 1978-04-12
Abstract: A method of expanding the bore of a metal pipe (11) uses a thick walled tube (12) with a bore equal to the required external dia. of the expanded pipe (11). A round bar (14) with a close fitting rubber sleeve (13) is fitted inside the pipe. The rubber sleeve is secured by end caps (15, 16) which grip the turned in ends of the sleeve. High pressure oil is pumped into the rubber sleeve through an axial hole and a radial hole (7) in the bar. This pressure expands the bore of the pipe until its outer surface touches the bore of the thick walled tube.

Title: High-pressure cleaner conversion equipment - with cold water delivered via instantaneous heater to safety spray gun
Inventor: WILMS KURT
IPC: B08B3/02
Filed: 1978-04-28
Abstract: The system converts high-pressure cleaning equipment using cold water for the production of hot water or wet steam at high pressure. The high-pressure cold water is delivered by a high-pressure pipe to an instantaneous water heater running on gas, oil or electricity, where its temperature is raised to between 80 and 150 deg. It is then delivered to a safety spray gun. A flexible high-pressure hose can be used to deliver the water to the heater, which is separately mounted. The normal cold-water control panel on the equipment can be replaced by one for hot water.
