Title: Plant irrigation system water content sensor - using thermal pulse probe in defined earth sample
Inventor: ISSEL WOLFGANG DIPL PHYS DR IN
IPC: G01N33/24
Filed: 1975-08-19
Abstract: A measurement sensor for determination of water in the earth is designed for sufficient accuracy for control of automatic irrigation installations. The probe uses the thermal pulse principle of moisture measurement applied to a known volume of sample earth with known characteristics. The sample earth (1) is enclosed in a fine net (2) placed in the soil (5). A thermal probe (3) with heating and temp. measurement windings is inserted into the sample and connected to further equipment via a cable (4). The moisture content of soil and sample earth are in equilibrium. The sample moisture content is periodically measured by recording the temp. of the probe before and directly after applying current to the heating coil for a short time. The temp. difference is a measure of the moisture content.

Title: Telescopic towbar with ratchet operation - has self locking clips to secure full length of towbar when under tension
Inventor: WIEGNER HEINZ
IPC: B60D1/155
Filed: 1975-10-07
Abstract: The telescopic towbar has two or more sections sliding inside each other for compact storage. Stops between the sections limit the extension of the towbar while radially operating ratchets (6) are spring loaded to drop into the towbar behind the inner sections when the towbar is fully extended, thus securing the full length of the towbar. The end clips (11) are similarly closed by radial ratchets and telescopic locking bars (12). The user clips each end of the towbar over the towing eyes on each vehicle, without having the towbar fully extended, or even in line with the vehicles. As the vehicles move off the towbar ratchets drop into place and secure a rigid assembly. The two sections can rotate relative to each other during use and thus prevent straining the coupling over rough ground.

Title: Planetary mixer for chemical process industry - esp. with simultaneous mixing and heating or cooling of product
Inventor: KIMMEL HANS
IPC: B01F27/96
Filed: 1975-12-30
Abstract: The parent patent mixer included a mixing vessel and a mixing element whose dia. was equal to the distance from the axis of the vessel to its inner wall surface. The mixing element described a planetary motion about the axis of the vessel and the direction of rotation of the element about its own axis was opposite to that of its orbital motion around the vessel axis. The angular velocity wm of rotation of the element was approximately equal to the angular velocity wp of orbital motion. In this addn. the mixing element is divided into two individual mixing rotors having equal rotational speeds wm and which sweep the whole cross section of the vessel. The mixing rotors revolve orbitally around circular paths of different radii at the same angular speed wp about the vessel axis. The masses of the individual mixing rotors, their orbit radii and angular speed of orbital revolution are all so related that the centrifugal forces to which the bearings are subjected are equal. The centrifugal forces borne by the rotor bearings are minimised.

Title: Clamp support for hydraulic hoses - comprises two semi-cylindrical shells placed around hose and held by conventional clamp to prevent wear on hose
Inventor: MCGEE JAMES MONROE
IPC: F16L3/123
Filed: 1976-12-28
Abstract: The clamping arrangement consists of two identical half cylindrical shells (12, 14). One edge of the shell has a protrusion while the other edge has a cut-out. The protrusion from one shell half fits in the cut-out in the other shell half. The ends of the shell halves are shouldered (28, 30). The two shell halves are placed over a hose. A conventional hose clamp with tangentional mounting lugs is placed over the shell halves. The width of the hose clamp is smaller than the length of the shell halves between the shoulders. The clamp is then used to fix the hose to a frame. Due to the use of shell halves, the rubbing of the hose in the mounting clip is transferred into rubbing of the shell halves in the clip, and the wear on the hose is reduced.
