Title: Aerial towed target balloon with collapsible envelope - is filled with hit indicating coloured gas and sinks to ground slowly
Inventor: FISCHER HANNO
IPC: F41J9/10
Filed: 1978-04-15
Abstract: The aircraft towed target has its body connected to the aircraft by a rope used also for target deformation. This target indicates hits without use of wireless transmitters and it will sink slowly to ground without any additional equipment. The towed target is a streamlined stable balloon with foldable envelope. This radar beam reflecting envelope accommodates a gas cartridge which is ignited when the balloon is extended and fills the balloon with gas at pressure. The gas is coloured and generates such a pressure that in case of a hit coloured gas is emitted. When the rope is disconnected then the balloon collapses and gas flows out and the target sinks to the ground slowly.

Title: Automatic control for hydraulic cylinder - has pilot valve operated by main piston and spring return changeover valve
Inventor: TANIGUCHI EIJI
IPC: F15B11/15
Filed: 1978-05-17
Abstract: A double acting hydraulic cylinder (1) contains a reciprocating piston (9). There is an oil port (19, 20) in each end of the cylinder. These are connected alternately to an oil supply pump (4) and an oil tank (7) by a changeover valve (3).

Title: Automatic sheet metal contact strip adjustment - uses storage of deformation data caused by stamping and/or plastics deformation for adjustment of straightening process
Inventor: MONAT HERMANN
IPC: H01H11/04
Filed: 1978-07-17
Abstract: The adjustment is carried out by a permanent deformation of the sheet metal contact strip by two stamping punches moving in opposite direction, one forming an anvil and the other a chisel-like punch, as in 2549897. First a basic adjustment is carried out during which characteristic values of each individual strip are detected. According to this basic adjustment is computed the deformation value, pref. by a microcomputer. This deformation value must result in the desired final position of the respective contact strip, while taking into consideration any plastic or elastic deformation taking place after the adjusting force has been stopped.

Title: Vessel for transporting milk samples - by storing and identifying individual samples in a cassette shaped container
Inventor: KIESTRA PHILIPPUS POPE
IPC: B01L99/00
Filed: 1978-09-27
Abstract: A container for milk samples consists of a solid block of a non-corrodible substance such as plastic, stainless steel or a combination of >=2 different materials. Cylinders are bored into the block from below which stop short of the upper surface. A small hole on the axis of each cylinder provides the communication between cylinder and upper surface. A piston is fitted into each cylinder acting as a seal to retain the sample in the cylinder and a means to push the sample back out through the opening. The container is positioned on a flat table under the sample machine, milk from the sampler being forced into the cylinder via the opening. As each successive sample is taken, the cassette is moved so that the next cylinder comes into the filling position. The cassette can be positively located in the correct position by means of recesses which correspond to each cylinder. Information relating to each sample, such as the cow name or number or the quantity of milk obtained can be recorded on an information strip which is fixed to the front face of the cassette. This strip may be of paper or a magnetic material. Stops or a recess in the face of the piston ensure that an air gap exists when the cylinder is filled. This enables the samples to be shaken before they are recovered from the cassette. The time consuming process and possible confussion of prior art are avoided. Used to judge the quantity of concentrates to feed to each cow.
