Title: Spring applied brake for pallet trolley - has hinged tow bar on axially moving brake rod through chassis
Inventor: FREY WILLI ING GRAD
IPC: B64F1/32
Filed: 1975-10-04
Abstract: The towbar of the pallet trolley is swivelled at the front of a brake shaft which slides along the middle length of the trolley, with springs to hold it in the extended setting. If the towing vehicle brakes then the braking force presses the brake shaft inwards, against spring pressure, and operates the rear wheel brakes of the trolley. The rear brake linkage is operated by brake levers on the brake shaft. The simple run over brake is not affected by the angle of the towbar. It enables heavy palletised loads to be moved without straining the towbar linkage, due to braking. The trolley is suitable for aircraft palletised loads, which can be heavy.

Title: Binder resin coatings for anchoring (rough) dowels or studs - using filled coatings top coated with hardeners for high key strength
Inventor: BUCHHOLZ JOSEF
IPC: F16B13/14
Filed: 1975-10-15
Abstract: Securing steel dowels in assembled components incorporating aligned blind holes, where the roles are wetted with a binder resin, and the dowel is precoated with a mixt. of resin and filler. The resin based composition applied to the dowel is subsequently treated with a catalyst or accelerator to promote curing. pref. by spraying or dipping the surface of the coating just prior to inserting the dowel into its hole. Suitable for assembling components, of e.g concrete or wood, e.g for construction of chairs. The dowel may have a round or square cross-section, may be a straight rod or an angle pin, and pref. has a rough or ribbed surface. Also suitable for anchoring one end of threaded or partially threaded bars, i.e to provide anchorage studs in a concrete foundation. The resin enhances the keying of the dowel within its hole to resist disturbance by vibration etc. Use of a deep coating is said to be stronger than thin gum coatings. Application of hardeners to individual coated dowels avoids waste of resin due to pot life limits of premixed coating compsns. incorporating hardeners. Some of the surface hardeners are transferred to the coating resin already within the hole.

Title: Electronic time switching device - uses resistive:capacitive timing and enables delayed relay switching with min. relay numbers
Inventor: SELINSKI ERWIN DIPL ING
IPC: H01H47/18
Filed: 1976-02-19
Abstract: An electronic time switching device with a time defining series circuit contg. a capacitor and charging resistor, a threshold switch, and an electromagnetic relay is designed to enable both pull-in and drop-out delayed switching commands and to reduce the required number of time relays. The charging of the resistor-capacitor element (R17, C1) takes place via a first operational amplifier (V11) and the relay is switched via a second amplifier (V12) acting as a threshold switch. The inputs (U1, U2; Uc, U4) of each amplifier (V11, V12) are switchable from the inverting to non-inverting inputs via switches (S11, S12) so as to produce delayed or undelayed pull-in or drop-out of the relay (K1). A second circuit (V13, V14, K2) supplied from the same power supply (V3, R5, V10) produces different delay effects.

Title: Sepg. catalyst from hydroxylamine salt prodn. mixts. - and treating with fluorosilicic acid to remove silica and silicates
Inventor: HELLENBRAND JOZEF MARIA HUBERT
IPC: C01B21/14
Filed: 1976-07-01
Abstract: Hydroxylamine salts are made by reducing nitrate ion or nitrogen monoxide with hydrogen in an acid medium in the presence of a noble metal catalyst. The catalyst mass is sepd. from the reaction mixt. and at least part of it is reused after first removing silicate and/or silicon dioxide by treating the catalyst mass with an aq. soln. of fluorosilicic acid at pH 1.5-4.5. Removal of the silicate or silicon dioxide deposits from the catalyst gives improved filterability of the catalyst from the reaction medium by preventing build up of silicate and silica deposits on the catalyst, which cause increasing filtration resistance. In an example, a palladium-platinum catalyst on active carbon carrier, activated with germanium oxide, was used for prodn. of hydroxylamine phosphate in the known way. After separation, the catalyst contained 4.9 wt.% SiO2. The catalyst was cleaned by treatment at 60 degrees C with an aq. soln. of fluorosilicic acid and ammonium fluoride at pH 3.7.

Patent DE-2711155-A1 (DE)
Title: Agitated mill for grinding suspensions - having agitator in vessel with conical projections to stir suspended milling agent
Inventor: PETER FRITZ
IPC: B01F7/00
Filed: 1977-03-15
Abstract: Agitated mill is for non-continuous grinding and prodn. of solid dispersions. It consists of a vessel in which is a rotating agitator having a shaft with a disc on the end. On this are mounted either side a series of elements shaped like two cones joined at the base and joined to the disc at the apex of one of them. This keeps the solids in suspension and causes the milling agent also in the vessel to grind them down. These elements are mounted either side of the disc and create a pushing, accelerating and impacting effect on the milling agent which is e.g. glass spheres. The shape of the elements is favourable to flow and is a body of rotation. They project to at least a quarter of their max. dia. above the disc surface. Used for making fine suspension, e.g. paint pigments, printing inks, paper masses, etc. Flat discs are known but are limited by the viscosity of the mix. The agitator claimed gives many times greater loading with better efficiency i.e. lower power for the same mix quality and less abrasion to the agitator. Less heat is generated in the mix.
