Title: Drive motor for machine tools - has toothed inner surface formed on rotor packet which is designed to give greater bonding to shaft
Inventor: BELLON WALTER
IPC: H02K1/28
Filed: 1975-07-26
Abstract: The drive motor, is for machine tools. It has its laminar packet, shaft insulation or bonding agent and shaft stabilised without extra cost so that the centre of gravity does not shift after the very first test run which warms up the above assembly. This shift in centre of gravity is avoided by incorporating laminae into the rotor packet that have holes of greater diameter than the general diameter of the holes through which the shaft passes. The two different sets of laminae give a toothed structure to the inside surface of the central hole through the motor which, when filled with the insulating bonding agent, gives a more rigid link between the shaft and packet.

Title: Aerodynamic lighter than air craft - uses shape to supplement gas for lift with engine thrust divertible for VTOL
IPC: B64B1/06
Filed: 1976-02-06
Abstract: The lighter than air craft is basically an airship so shaped that it derives an element of lift from forward motion. The propulsion units (2) some in the sides of the craft but most in the equivalent to the trailing edge, are contained within the hull outline but their thrust can be directed downwards for VTOL. There are also facilities for the rapid for-and-aft transfer of ballast/buoyancy-medium to alter the craft's attitude and line of flight. Access is by a rotatably extendable trunking (1). This can also be used for holding the craft on the ground, magnetically or by boring into the soil. For max. economy hot gas from the engines can be used as a buoyancy medium. However the craft will anyway need less gas than a conventional airship since less is required for lift and none need be wasted by discharge for control purposes.

Title: Rotary vane pump with eccentric rotor - has vol. variation by superposing on adjacent rotary vanes relative movements in addition to rotation
Inventor: KELLER GUENTER
IPC: F04C2/07
Filed: 1976-04-13
Abstract: The rotary vane pump has eccentrically mounted rotor carrying radially sliding vanes. The vol. of the vane cells formed by two adjacent vanes can be varied during one revolution of the rotor. The pump is fitted with stator windings and windings on the rotary vanes are connected to the power supply. A magnetic field builds up in the windings and the rotary vanes are attracted and/or repulsed by the rotary magnetic field. A certain number of poles may attract rotary vanes in its proximity, while another rotary vane set positioned in another part of the circumference of the stator windings acts against the rotary field and is being retarded in its rotary movement. The resulting effect is, that the volume of two vane cells decreases, whereas the volume of the rest of the cells increases at the same time.

Title: Safety matches prodn. - by cooking binder with water, adding potassium chlorate, mixing in mixt. of remaining solids and homogenising with entrainment of air
Inventor: LEMME REINHARD ING GRAD
IPC: C06F3/00
Filed: 1976-10-08
Abstract: Ignition materials for safety matches etc., consisting of water, binder, potassium chlorate, fillers, phlegmatisation agents, sulphur, catalyst and opt. pigments, are produced by (1) cooking the binder and a preservative with the necessary amt. of water to form a first mixt.; (2) dry mixing the remaining solid components, with the exception of the potassium chlorate, until >=90% of the particles are 0.1 mm; and (3) dissolving the potassium chlorate in the first mixt. and mixing the resulting soln. with the second (dry) mixt. in such proportions that the final mixt. has a density of 1.75 to 1.95 g/cm3, and homogenising the resulting mixt. with entrainment of air until the density has fallen by 0.35 to 0.55 g/cm3 and is 1.5 g/cm3, so as to avoid further comminution of the solid particles as far as possible. The process allows the mixts. (1) and (2) and unmilled potassium chlorate to be transported for use in places remote from the production site for the prim. mixts. These mixtures can be transported safely and can be made up on site to take account of local variations in temperature and humidity, thus giving consistent results irrespective of the location of the plant and the seasonal weather conditions. The sharpness of ignition can be adjusted by varying the homogenisation time.
