Title: Offset printing plate damping process - using steel water roller coated with resin film to protect damping rollers
IPC: B41N7/04
Filed: 1976-02-16
Abstract: The steel water roller of an offset printing machine has its surface coated with a film-forming compsn. which is applied in soln. in a solvent, pref. water, and is miscible with water after evapn. of the solvent. The film-forming compsn. comprises (a) natural or synthetic gums or polyvinyls, (b) a tanning ageant, pref. a Cr salt, (c) a catalyst for (b), pref. HCHO or HCOOH, (d) an agent to provide an acid pH, e.g. phosphoric acid and (e) a surfactant. During rotation of the roller a protective film is formed on the damping roller(s) which thus become protected from the ink on the printing plate. Use of a fabric lining over the damping roller surface is obviated. Amt. of water necessary to wet the printing plate is also reduced.

Title: Travelling crane control system - has separate command vehicle measuring item position and generating movement control pulses
Inventor: DANIELI HENRIK
IPC: B66C13/48
Filed: 1976-03-22
Abstract: The system is for use with a crane having a travelling gantry, on which a crab with hoist in turn travels. There is a command vehicle, separate from the gantry, and equipped with measuring devices determining the position of an item or a surface. The values recorded are stored in a memory and the positions of the item and gantry compared. An arithmetical control unit transforms the estimated distance values into control pulses, which move the gantry and/or crab into the desired positions in relation to the item. The command vehicle can travel on a track parallel to that of the gantry.

Title: Cylinder for vehicle disc brake - has location provided by reaction bracket and external anchor bolt
IPC: F16D55/226
Filed: 1976-03-25
Abstract: A vehicle disc brake assembly is attached to a fixed mounting bracket (10). The brake piston (44) acts on the friction pad (23a) on one side of the brake disc (11). A reaction bracket (14) transmits the reaction force from the brake cylinder (42) to the friction pad on the other side of the brake disc (11). An anchor bolt (60) for the brake cylinder is provided outside the cylinder and parallel to its axis. An external fork (65) on the cylinder engages the anchor pin (60). Any lateral forces which are produced when the brakes are applied are thus taken up by the anchor bolt location.

Title: Making essential oils water-soluble - by adding mixt. of anionic and nonionic surfactants
IPC: A23L27/00
Filed: 1976-11-30
Abstract: Essential oils are rendered water-soluble by combining them with a combination of about 2/3 of an anionic surfactant and about 1/3 of a nonionic surfactant. Pref. anionic surfactants are sulphonate or sulphate types, alkaline soaps of fatty acids, slats of organic bases, or modified starches e.g., oxidised starches. Pref. non-ionic surfactants are polyglycol ether types or block copolymers, alkylamine ethoxylates, condensates of ethylene oxide with octyl-phenol, or ethoxylated alcohols and fatty acid and sorbitol anhydride derivs. About 15 wt. % on the oils of hte combination is used. According to the quantity of water used, the water-solubilised prod. is an elastic gel, a semi-liq. paste, or a fluid soln. No particular order of mixing is required. The surfactants confer ready water-solubility on the oils without the aid of organic solvents. The water-solubilised oils have the following properties: (1) they can remove fatty soil; (2) they foam relatively little; (3) their solns. are neutral, clear and homogeneous: (4) their bio-chemical and physiochemical properties are fully preserved, i.e., their efficiency as bactericides, bacteriostats, deodorants, insecticides, osmotic and diffusion agents, etc.; (5) they have (a) improved detergent power, (b) better wetting properties, (c) lower surface tension, (d) lower inter-facial tension, (e) dispersing power.

Title: Lid safety catch for washing machines with high speed rotary drums - to prevent access to the drum before it can be stopped
Inventor: MARIJON MARCEL
IPC: D06F37/42
Filed: 1977-02-18
Abstract: An electro-mechanical interlock fits to washing machines to ensure that access to the drum is not possible during high speed spinning cycles until after the drum has come to rest. Interaction between an L-shaped finger on the lid and a sliding catch in the machine casing activates a relay which extends a mechanical stop so that the lid cannot be disengaged until after the spinning cycle is completed and the stop withdrawn. Used esp. for machines with drum rotation speeds of >=800 rpm., to inhibit injury before the drum has run down to a halt after the motor has been de-energised.

IPC: C07C4/06
Filed: 1977-06-03
Abstract: Combined process for ethylen prodn. in which (a) a normally-liquid hydrocarbon fraction is passed with excess H2 through a catalyst-free thermal hydrocracking zone under conditions which give a product free from non-aromatic hydrocarbons with more than 3C atoms; (b) a hydrocarbon stream contg. 2 or 3C atoms is separate by low temp. processes, (c) the stream is passed to a cracking zone and converted mainly to ethylene, adn (d) the unreacted hydrogen from (b) is recycled to (a).
