Patent DE-2455688-A1 (DE)
Title: Electro-magnetic brake with manual release - is operated by rotating eccentric bolts when solenoid is de-energised
Inventor: WEBER HERBERT
IPC: F16D65/14
Filed: 1974-11-25
Abstract: The device is applicable to electric motors with spring loaded brakes which are released by the energising of a solenoid when the motor current is switched on. An eccentric bolt (8) is attached to either side of the motor casing (1). The bolt can be rotated with a key which is inserted in the socket head (14) and this causes the claws (9) to move axially. The tip (11) of the claw then pulls the brake disc (17) clear of the brake lining (5). The brake is thus released without switching on the motor current. Holes are provided in the motor cover (12) for access to the bolts (8).

Title: Band clip with screw thread - has single piece housing holding tightening screw with recess below screw head
Inventor: ZEIDLER SIEGMUND
IPC: F16L33/08
Filed: 1975-02-17
Abstract: The clip is for hoses and pipes and has a tightening screw turning in a housing with V-shaped cross section and with edges turned inwards. The design overcomes the difficulty with a conical screw head that under high loading the screw can spring out of position. The shank of the screw is longer than the housing and the housing rim fits in a recess below the screw head (3). In the normal position there is a clearance between the housing and the base of the screw head, this clearance being less than the thickness of the housing material. The housing deforms as the screw is finally tightened, holding it in position.

Title: Coloured anodized coatings on aluminium - for structural elements and facings (NL131076)
Inventor: NIPP ERNST
IPC: C25D11/22
Filed: 1975-04-11
Abstract: The production of the coloured anodized coating on Al for decorative structural elements and facings, comprises (1) the formation of a porous naturally coloured anodized coating on the base metal, (2) bringing pigments to the pores by applying an electrical potential at the colouring electrolytic soln. and therefore at the anodized coating in such a way that only the lower portion of the pores facing the base metal are filled with the pigment, and (3) filling the rest of the pores with other types of pigments. This gives a coloured anodized coating of various intermingling shades.

Title: Control for steerable camera dolly - has two clutches for simultaneous swivel control linked to one lever
Inventor: ZELLI SANTE
IPC: B66F11/04
Filed: 1975-09-19
Abstract: The camera dolly has a U-shaped frame (10) with four wheel sets (19-21) set at the corners on horizontal arms swivelled about vertical axes (23-25e. A single manual control (27) at the front is pivotted about a vertical axis and controls the steering of the dolly in either a crabwise fashion or a curving track. Two selective clutches are operated by a ratchet lever to couple the control to the chain drives linking the control to the steering axes, in one of two members. In the one setting all the axes operate together. In the second setting the front and rear axes operate in opposite ways for steering round curves. The control is simple to operate single handed.
Patent DE-2542663-A1 (DE)
Title: Valve piston for water tap - with hydrostatic valve piston control operated by internal magnetic coil or hand lever
Inventor: ABELE HELMUT
IPC: F16K31/38
Filed: 1975-09-25
Abstract: A water tap houses a valve piston which closes the outlet port. The piston is held in the closing position by a compression spring and the water pressure in the control chamber. A magnetic coil inside the valve piston controls the pilot valve with which the water pressure in the control chamber can be reduced. The reduced control pressure allows the main valve to open due to the inlet water pressure. After a set time, the water that flows through a throttle fills the control chamber and establishes pressure balance, thus closing the tap. The valve can be operated by energizing the magnetic coil or by operating the hand lever.

Title: Telephone system interference reduction method - measures time intervals between signal zero crossing, followed by main test
Inventor: BALL HERBERT
IPC: H04Q1/46
Filed: 1975-10-18
Abstract: A method for reducing the likelihood of interference for selected receivers in telephone systems, first carries out half or full period tests of large bandwidth in each signal recognition process at the zero crossings. If the result is positive, a main test of small bandwidth, extending over a number of periods is carried out. If a negative result appears during a half of full period test during the main test, this test is stopped. The above action is permitted only when a certain number of negative half or full period tests, depending on the frequency of switching clicks on the transmission line, is detected during the main test.

Patent DE-2611960-A1 (DE)
Title: Differential press. indicator - to register fouling,esp. of oil filters in engines
Inventor: WILLIS WILLIAM MARDEN
IPC: B01D35/143
Filed: 1976-03-20
Abstract: A differential press. indicator shows only that press. drop which is due to fouling across a component, such as a filter, in a fluid system. The indicator employs a piston having two surfaces. The press. upstream of the component acts on the first surface and the press. downstream acts on the second surface. The forces on the piston due to the two pressures, acts in opposite directions. A differential arrangement provides the second surface with a mechanical advantage over the first, whose magnitude is such that the force resulting from the downstream press. (i.e. the lower press.) is greater than that resulting from the upstream press. under normal conditions when the filter is clear. The press. drop required to overcome the mechanical advantage is the predetermined max. allowable press. drop through the filter due to fouling. When this press. loss is reached, the piston responds and an indication is given by a visual device. Used esp. for oil filters in I.C. engines. Reliable indication of the true degree of fouling maximises filter utilisation and reduces wastage and pollution due to oil spillage when filters are replaced. The indicator operates accurately regardless of varying engine speeds and other variables influencing the press. in the system.

Title: Exhaust gas purifying system - has valve device in air channel which opens when cylinder exhaust pressure falls
Inventor: TAMURA TETSUOMI
IPC: F02B75/20
Filed: 1976-04-20
Abstract: The exhaust gas cleaning system is for a four stroke combustion engine where the cylinders (2) are combined as cylinder groups, each of which comprises two cylinders. The opening times of the outlet valves (6,A) in each cylinder group do not overlap. An air channel (14,17,18,19) connects the exhaust channels (12,7) of the cylinders of one group with atmosphere. A valve (13,13') in the air channel automatically opens when the pressure in the cylinder exhaust channels of one group falls below a given value. Consequently air is passed into the exhaust gas channels of the cylinders of this group.

Title: Scraped surface crystallising vessel - having heated plates scraped by blades fitted to central rotor
Inventor: GALPERIN JEVGENIJ NAUMOVITSCH
IPC: B01D9/00
Filed: 1976-05-25
Abstract: A crystallising appts. is described in which heated plates inside a closed vessel induce evaporation of fluid and hence precipitation of crystals. A rotor filled with a number of blades ensures thorough agitation of the fluid in the vessel, and at the same time ensures that any crystals adhering to the heated plates are removed. The appts. is used for crystallisation of solns. in the chemical and food industries. The scraped surface of the heated plates ensures good heat exchange properties and allows the appts. to be used continuously without having to be shut down periodically for removal of adhering crystal deposits.
