Title: Housing for accommodating cylinder lock and key and handle - has symmetrical halves with cylindrical feet and closing plugs and connecting dowels
IPC: E05B9/04
Filed: 1974-09-10
Abstract: The housing unit which is built up from separate components is cheaper to manufacture than an integral housing. The housing accommodating the cylinder lock, key, handle and the dowels consists of two symmetrical halves each of which has a semi-cylindrical seat. This form as cylinder on the assembly which accommodates aligned cylinder lock components. A central opening is provided at mid length for accommodating the key.

Inventor: SOKOLOV LEV BORISOVICH
IPC: C08G63/40
Filed: 1974-09-23
Abstract: Aromatic polyesters are prepd. by reacting diphenols with aromatic dicarboxylic acid dihalides, in molar ratio 0.9-1.1, at -10 to +30 degrees C, in presence of 2-2.5 mole alkali/mole biphenol, in a system consisting of water and an organic liquid (I) which dissolves the acid dihalides, is inert towards initial reagents, and is present in water: (I) vol. ratio of 0.2-5. The reaction takes place in the presence of 5-45 wt. %, w.r.t. water, of >=1 water-soluble salt (II) of a Gp. I or II metal and with use, as (I), of an organic liquid which is >=25% miscible with water. The polyesters are used as self-lubricating sliding plastics, workable to foils by casting or extrusion; and are useful in electrical and radio-engineering, electronics, aeroplane and machine construction. The high MW, high heat-resistance polymers are obtd. in high yields, e.g. 99.7%; can easily be washed out of (I) and are free from additives. The amount of hydrolysable dihalide is reduced by addn. of (II).

Title: Hexagonal corrugated cardboard display carton - has closed and open compartments formed by flaps on walls hinged to half of edges of base
IPC: B65D5/20
Filed: 1975-01-06
Abstract: The carton is made from a one piece blank of corrugated cardboard. The base (1) is an isosceles triangle with each side divided into three sections whose intersections are joined by fold lines to form a hexagon. The three free edges of the hexagon have rectangular walls (2a, b, c) attached by fold lines, one wall (2c) being attached to the top (6) which is similar to the base. Folding up the rectangular sections causes the three corners of the base to fold in and form compartments using flaps (3a, b, c, 4a, b, c), attached to the edges of the walls. The edges of the flaps meet at the centre of the base and form three closed compartments alternating with three open compartments.

Title: Multiple motor electric vehicle wheel control - has motor armatures connected to triple wound transformer for driven wheels
IPC: B60T8/1761
Filed: 1975-10-03
Abstract: The traction motor armature winding connections are fed via resistors (111, 121) to two reverse wound primary coils (21, 22) of a triple wound transformer whose secondary winding (23) is connected to a threshold and value former (4). These outputs are integrated (5) and fed to a comparator (6) together with one input from the brake pressure reduction stage (9) and a second output from the required braking pressure transmitter (8). The output is transferred to the brake regulator (10) which is varied corresponding to the degree of wheel slip. The comparator (6) produces a binary signal on receiving a reduced output from the integrator stage which causes a regulator (7) to switch off the traction power and also continually reduces the output signal corresponding to the required braking pressure.

Title: IC engine carburettor - gives weaker than normal fuel ratio and increases ratio on cold start proportionate to load
IPC: F02M1/04
Filed: 1976-02-25
Abstract: Carburettor has a start system comprising of an air intake channel whose one end is connected to the engine inlet manifold and the second end to an air filter. The starting air intake channel has a manually operated slide valve and a taper needle entering a fuel jet communicating with the float chamber. The upper region of the float chamber is subject to inlet manifold depression via a restrictor and pipe line. The engine is started with the slide valve open and fuel is drawn from the jet owing to the narrow cross section of the starter intake channel in comparison with that of the main intake. When the main throttle valve is opened, air flows through the main induction channel without drawing fuel from the idler jets to weaken the start mixture from the starter channel, which has become richer owing to an increase in pressure in the float chamber as a result of the pressure increase in the induction manifold.

Title: Carpeting dye transfer process - uses carrier bands joined with displaced patterns to compensate for shrinkage
IPC: B41F16/02
Filed: 1977-05-13
Abstract: The transfer printing process for textile fabrics, such as carpetings or wall coverings, uses a continuous fabric and a continuous inert carrier for the dyestuff to be transferred by heat and pressure to one side of the textile. The carrier is composed of long patterned strips which run across the carrier and are joined together, and before the carrier is brought to the fabric the sides are joined to two adjacent carriers. The patterning on the side carriers is displaced from the central carrier by a value which is at least the sum of the anticipated shrinkage between one carrier and another in a lateral direction under process temp. When heat and pressure are applied to transfer the dye pattern, the patterns in the carriers join exactly. The process allows broad carpetings and other materials, of 4-5 m width, to be patterned by a transfer dye technique.
