Title: Weedkiller applicator for lawns handles easily with spot - application and controlled dosage
IPC: A01M21/04
Filed: 1969-08-22
Abstract: Liquid weedkiller applicator for lawns is easy to handle and works on the spot by spot eradication principle. A chamber walled in semi-stiff transparent polyethylene stocks the weedkiller fluid and connects to a porous pad of foamed polyester of sufficient section to allow fluid out onto the weed when the pad is contracted and reexpanded a valve in the chamber seal consists of an orifice in a screw cap and an orifice in an inside flange on a screw connector, so that with the cap screwed home the orifices lie out of contact. Only by partly unscrewing the cap can be orifices be lined up to control air entry to the chamber. Specifically, the pad and chamber are coupled by a cylindrical extension of the chamber wall, and the pad is held in place by a retainer ring fixed on the outside of this extension piece.

Title: Polybutadiene rubber/urea mixtures to prevent frosting
IPC: B65G47/95
Filed: 1970-03-04
Abstract: 0.1-3 wt.% (referred to rubber) of urea is added to blend before vulcanisation to prevent frosting in coloured vulcanisates of butadiene homo- and co-polymers and usual additives. Relatively small amount of additive is sufficient and it does not increase cost of blend. Urea causes no discoloration in light and can be used in blends coming into contact with foodstuffs, being physiologically harmless.

Patent DE-2212175-A1 (DE)
Title: Removing flash from filled blow-moulded containers -
Inventor: KELLER WILHELM
IPC: B29C45/00
Filed: 1972-03-14
Abstract: The mechanised multi-impression arrangement picks up extruded tube sections and moves them to guns which blow them out into moulded containers and fill them with liquid. A gripping device comes to the mould and grips the container head flash, whereupon the mould opens and returns to the extruder. Gripping segments hinge together to clasp the containers in pick-up cavities. Claws swing under the containers and press them upwards into cutting tools which removes the head flash while bottom cutters remove base flash. A suction duct draws off the flash. The gripping segments then drop down and release the filled mouldings onto a belt.

Title: Chemical deposition of titanium cpd(s) - with c arbon and/or nitrogen onto metallic or nonmetallic substrates
Inventor: HAYMAN CECIL
IPC: C23C16/32
Filed: 1973-05-10
Abstract: Stream of titanium chloride or bromide is passed over a B, C and/or N source at a high temp (but below 1200 degrees C) and the resulting cpd. of Ti with B, C and/or N is deposited on a metallic substrate (e.g. industrial diamonds can be provided with an electroconductive coating). This method is improved in that the atomic ratio Cl(Br):Ti is considerably less than 4:1 (pref. =3.2:1), and the presence of the lower chlorides or bromides of Ti promotes the formation of a fine grain coating having increased abrasion resistance and hardness. This method is esp. suitable for prodn of TiC coatings.

Title: Determination of heat consumption of consumer heating system - has heat consumption meters and temperature difference measurement
Inventor: LOEWENHOFF PETER DIPL ING
IPC: G01K17/08
Filed: 1974-02-15
Abstract: The thermal efficiencies are determined for the radiators by electrical measurements of the temperature differences between the radiators and the surroundings. By the use of operational amplifiers the results of the temperature difference measurements are multiplied by coefficients which correspond to the size and type or the thermal efficiency of the individual radiators. They are added together to obtain an electrical variable which then corresponds to the thermal efficiency of a consumer heating system. The temperature differences between the average temperatures of the radiators and the ambient temperatures can be measured.

The ceiling system is assembled from individual cantilevered fire-retarding elements, as long as the width of the area to be protected, in the region of the ceiling. At their end faces they are borne by holding-media mounted on the walls at an interval below the main ceiling.

Title: Stabiliser for vehicle linear motor servo - with separate servos for front and rear edges of stator
Inventor: MRHA WILFRIED DIPL ING
IPC: G05D3/14
Filed: 1974-04-17
Abstract: The linear motor driven vehicle has a stator which is held at a set spacing from the guide rail. For high speed vehicles the incidence of resonant vibrations between the stator and rail lead to poor performance. The system is provided with monitors at the front and rear edges of the stator to separately operate compensating servos for the two ends of the stator. This provides a non-resonant centering system for the stator and enables relatively narrow air gap to be maintained for high speed vehicles. The arrangement is particularly for rail vehicles.
