Title: Pneumatic post slug diverter mechanism - has pivoting tube section with closed end and air slots in sides
Inventor: HOLTHUS DIETHER E
IPC: B65G51/24
Filed: 1974-01-17
Abstract: A pivoting tube section contained in an airtight housing swings into alignment with two or more pipe runs. It is sealed airtightly at one end nad has air slots at a distance from this end, at the most equal to the distance from the forward end of the slug to the ring furthest from this end. The pivoting section can have a sealing device acting in conjunction with the ends of the pipe runs, typically of the sliding sleeve type, its drive being taken from the mechanism pivoting the tube section. Thus the incoming slug creates a buffer of compressed air on passing the slots, between it and the sealed end, and on swinging the tube into line with the outgoing run air flows into it through the slots to a space behind the ring on the slug, to drive it out again.

Title: Wind turbine to extract energy from wind - has vertical rotating drum closed at top supported on rollers
Inventor: MALZAHN EUGEN
IPC: F03D3/06
Filed: 1974-03-07

Title: Electromagnet latching means for solenoid plunger - gives reduced dimensions and energy consumption and faster response
Inventor: ONATSEWITSCH MICHAIL ALEXANDRO
IPC: H01F7/16
Filed: 1974-04-24
Abstract: A solenoid assembly or plunger-electromagnet comprises independently wound working and auxiliary armatures.

A fixed locking cylinder is coaxial between the windings of the armatures. The working armature has axial movement within the locking cylinder, and the auxiliary armature has relative axial movement on the outer surface of the locking cylinder. Spring means urge the auxiliary armature towards the working armature. The locking cylinder includes circumferential apertures caging radially-displaceable rocking balls engageable between a conical stop portion of the working armature and retained there by the inner surface of the auxiliary armature to maintain the working armature fixed in the absence of energization of the working armature coil.

Title: Triglycerides determination in body fluids - by hydrolysis, lowering pH with glycine to avoid pptation, then enzymatic assay of glycerine
Inventor: RISCHKA WOLF DIPL ING DR
IPC: C12Q1/48
Filed: 1974-07-09
Abstract: In determining triglycerides (I), esp. in body fluids, by hydrolysis; lowering the pH of the hydrolysate; then determining glycerine by (a) reacting with ATP in presence of glycerokinase to give glycerine-3-phosphate and ADP; (b) reacting the ADP formed with phosphoenolpyruvate in presence of pyruvate kinase to give pyruvate and ATP; and (c) reducing pyruvate with NADH to lactate and NAD+ in presence of lactate dehydrogenase (the NADH being the species whose concn. is actually monitored), the pH of the hydrolysate is lowered by adding glycine or another buffer which does not cause interfering precipitation. Since there are no precipitates formed automatic analysers can be used and no blank measurement is required. Hydrolysis is effected with a readily available reagent (contrast use of lipase).

Inventor: BEYER HORST DR ING
IPC: B22D15/02
Filed: 1975-01-15
Abstract: In a process for the prodn. of cast articles having surfaces with high wear resistance and in partic. cast iron machine sections with frictionally loaded surfaces, the surfaces of the cast sections are melted and cooled with the simultaneous addition of alloying elements. The methods used for the surface melting process are generally electron beam or laser beam proceses and/or high frequency electrical methods. The alloying additional elements added are usually bismuth, boron and/or tellurium and may be added as pure individual elements or as alloy mixts. themselves. EXAMPLE 10 mg Te powder was scattered on an unalloyed cast iron body (6 x 12 x 60mm) and the surface of the body was arc melted to a depth of 2.5mm. After cooling, the surface was almost completely ledeburitic. The body could be used as a sealing member for a rotary piston engine.

Title: Sweets moulding process - in cavity moulds sprinkled with moulding powder before and after pouring of sweetmeat solution
Inventor: BUYLTON-DOMGRAFF RALPH VAN DER
IPC: A23G3/16
Filed: 1975-02-22
Abstract: Sweets are produced by pouring a liquid sweetmeat soln. into the mould cavities of solid moulds. The walls of each cavity first receive a lining of a moulding powder which acts as a parting agent. The free surface of the poured sweetmeat also receives a coating of a moulding powder. This process is not limited to chocolate but can be applied to jellies and fondant. It requires much less moulding powder than the MOGUL process and saves the labour and cost of the power reconditioning.

Title: Simple switching mechanism and circuit for electric lawnmower - has hand operated main motor on and off switch and automatic overload cutout
Inventor: DREBES ARMIN DIPL ING
IPC: A01D34/68
Filed: 1975-03-14
Abstract: A simple but practical circuit and its associated mechanism is used in an electric lawnmower, in which the main motor switch is hand operated and in which an overload cutout is provided. The mechanism is a simplification of that used in traditional lawnmower circuits. It consists basically of an on-off switch (4) in series with a cutout switch (3) and the lawnmower drive motor (1). The on-off switch is operated by a lever (8) attached to a cable (11) and through this to a handle (12), mounted on the guide or handlebars of the lawnmower. The handle incorporates a latching mechanism (16). The operating lever operates a cutout switch (3, 5) when an excessive movement is made through the cable (11). The whole mechanism is spring loaded.
