Title: Coating layer for screws - reduces friction to make insertion and removal easier particularly in wood
Inventor: WICHMANN GEB OEHM MARGOT
IPC: F16B33/00
Filed: 1975-02-12
Abstract: The design requires very much less effort to join connectors together or to screw into another material if a friction reducing layer is used. The friction reducing layer is used on the contact surfaces of bolts and nuts and especially on wood screws and nails. The covering layer binds onto the surface and provides corrosion protection. The covering for the screw does not stain or produce flaws in the wood as it is screwed in. The covering is usable over the normal temperature range. The covering layer can also be used on pipes or channels so that attachments can be easily fixed to them.
Patent DE-2506985-A1 (DE)
Title: Weight determination appts - output comprises given number of weight digits with automatic error correction control
Inventor: LOSHBOUGH RICHARD C
IPC: G01G23/37
Filed: 1975-02-19
Abstract: The gauging device produces a digital weight signal which has at least one other lower value digit than the weight output. A zero correction factor is stored and periodically a corrected weight is produced from the algebraic sum of the produced weight signal and the zero correction factor. The given number of highest value digits of the corrected weight contains the weight output. If the corrected weight falls within a given small weight range, the zero correction factor is periodically modified. The gauging device contains a load cell which produces an analogue output signal proportional to the weight of an object.

Patent DE-2510719-A1 (DE)
Title: CO-content-related burner control - has oxygen ion-conductive ceramic solid state element within flame tip area
Inventor: HEIMKE GUENTER DIPL PHYS DR
IPC: F23N5/24
Filed: 1975-03-12
Abstract: As the allowable gas velocity in conventional pipings is limited to values necessarily below turbulent conditions, considerable response time lags occur. By placing the oxygen ion-conductive ceramic at a certain point within the flame tip area this time lag is eliminated. Tests have proved that even for various sizes of burners and various load ranges it is possible to determine a certain position of the detector, which is sufficiently representative for the operation condition of the burner, i.e. for the CO-content of the flue gases. The detector is capable of producing a signal of well over 10 mV, if the combustion conditions deviate from the required value.

Title: Variable transmission with hydraulically controlled 'V' belt pulleys - one side of each pulley produced as piston supplied with pressure regulated hydraulic fluid
Inventor: LUDOPH HEMMO HERMANNES JOHANNE
IPC: F16H61/662
Filed: 1975-04-25
Abstract: A continuously variable power transmission system uses hydraulically controlled 'V' belt pulleys to vary the transmission ratio. The input pulley consists of a fixed section (4) coupled to the input shaft (1). The moving side of the pulley is formed by a hydraulic piston (3). A similar unit is used for the output pulley with the exception that the piston diameter (6) is smaller than the input piston. The pressure applied to the output stage (Ps) is determined by the spring rating (16) of a relief valve (14) in the supply line from a gear pump (13). The pump output is also taken over a spool valve (18) to regulate the pressure (Pp) applied to the input pulley. Once the secondary pressure has been set at a constant value the primary pressure (Pp) may be regulated to give the required transmission ratio.

Title: Control linkage for two clutches - with stepping lever for alternate application about variable pivot point
Inventor: MAUCHER PAUL DIPL ING
IPC: B62D11/08
Filed: 1975-06-18
Abstract: The two clutches of the tractor, or construction vehicle are operated by a single clutch pedal, with one clutch at a time coupled to the linkage. The single input shaft from the clutch pedal is linked to the two output shafts (2, 3) by a pivotted yoke and by a pivot, stepping cam which alters the pivot point of the yoke and which coupled one output shaft at a time to the input shaft. After the input shaft has travelled the distance equal to the clutch free travel the stepping cam starts to swing into a second setting so that when the clutch pedal is released the second setting is coupled to the input shaft. The system eliminates complex switching controls, and has the advantage of similar pedal travel for either clutch.

Title: Headphones with pyramid shaped ear cups - has lateral openings allowing sound to emerge in front of face
Inventor: LEPPER WILHELM DR ING
IPC: H04R1/10
