Title: Oxygen-hydrogen engine including steam generator - has valve-controlled expansion tubes as opposite sides of explosion chamber
Inventor: HOHMANN HERBERT
IPC: F01K25/00
Filed: 1974-10-24
Abstract: Oxygen-hydrogen engine has a central explosion chamber provided with opposite expansion tubes closed by respective valves. The chamber and tubes are surrounded by a boiler connected to a supply of low temperature steam.

Title: Fulling machine esp. for felt fabric - has pressure beams between adjacent rollers to process thick materials
Inventor: GOEBEL VOLKER
IPC: D04H17/12
Filed: 1974-07-12
Abstract: The fulling machine has a pressure beam between each roller. Each pressure beam is profiled on each side with a concave surface. Each pressure beam is pref. hollow, with an approximate rectangular cross-section, with the long side walls curved to match the dimensions of the rollers on either side. The pressure beams can be heated, together with the rollers, the hollow beams allowing the insertion of heaters or a heating medium can be passed through them.

Title: Discharge nozzle assembly for plastic bag - has npzzle tube screwed into internal seal ring with conical projecting fastener
Inventor: KROMER HORST
IPC: B67D3/04
Filed: 1975-06-05
Abstract: The plastic bag has a discharge nozzle assembly which allows a controlled material flow when the bag is being emptied.

Title: Elastic threaded sleeve for attachment to plain tube end - has external thread for tube connection, and compressible split ring clamping insert
Inventor: ZEIDLER HANS-JOACHIM
IPC: F16L25/00
Filed: 1975-08-18
Abstract: The screw sleeve is made from rubber or plastic and has an external thread which is located between two smooth cylindrical end sections. The inside of the sleeve has a location groove for a metal clamp ring and sawtooth recesses cut in the wall. The opposite sleeve end is provided with an internal stop flange against which the end of the metal tube lies. After the sleeve is pushed over a metal tube end a hose clamp ring with a square expansion loop is eased over the outside of the sleeve. This contracts the metal clamp ring on the inside of the sleeve so that a firm joint between tube and sleeve is obtained. The metal clamping ring has an oblique slit in its surface allowing it to contract in diameter.

Title: Remote controlled toy boat with reversible propeller - has rudder located ahead of propeller causing boat to change course on reversal
Inventor: MUELLER-SEIDEL KLAUS
IPC: A63H23/04
Filed: 1975-09-23
Abstract: A remote controlled toy boat (1) has a reversable propeller (7) which is located along the boats centre line at the stern. The rudder (3) is also located on the same centre line, but ahead of the propeller (7). The rudder is able to pivot about a vertical shaft (4) to a fixed position of about 30 deg.. When the boat moves backwards, the water pressure on the rudder (3) forces it to swivel in its angular position. This produces a turning moment about a vertical axis. Thus the boat alters its course. For forward motion, the rudder is operated by normal remote control.

The capillary part containing the mercury and used for temperature reading is twice bent over 180 deg., so that three capillary branches of approx. the same length are produced. The central branch is completely filled with mercury. Each of the other two branches containes one of the two boundary surfaces.

Title: Yarn tensioner for yarn storage drum - has two or more tensioning rings arranged axially over one another around drum
Inventor: LAWSON JOHN B
IPC: D04B15/48
Filed: 1975-12-11
Abstract: The tensioning unit has >=2 tensioning rings supported on a ring which encircles the drum ear its lower end and is held by a fixed support.

Title: Motor vehicle door lock cap - is used to prevent entry and freezing of water in lock
Inventor: IHNENFELDT ARTUR
IPC: E05B17/00
Filed: 1976-01-22
Abstract: The protective cap is for a motor vehicle door lock, and is made of rubber or flexible plastics. The cap is provided with an eye ring, and is used to protect the motor vehicle lock in wintertime against ice or snow or freezing rain. The cap prevents entry of water and subsequent freezing in the lock, which would prevent opening of the lock. The upper closed part of the cap has an eye ring through which can be passed a chain or string for holding the cap on the door handle. This prevents loss of the cap when it is slid off the cylindrical projecting lock barrel.

Title: Demountable fitting for furniture castor - has slotted plastic wedges and spreading bolt held stationary by claw inside leg
Inventor: PAAS WERNER
IPC: B60B33/00
Filed: 1976-03-31
Abstract: The castor bearing (13) is fitted with a threaded shaft (15) set through two plastic wedges (20) set in opposite directions. The wedges are pushed into the hollow leg of the furniture item and the shaft tightened to splay out the wedges and secure the castor. For an improved fitting the wedges are slotted so that a wider splay movement is obtained. This allows the fitting to be used on non even bores. The bottom wedge has a claw (38) which grips the top part of the bearing and prevents the wedge from rotating while being tightened, while the mating faces (21) of the wedges have ratchet grooves to lock them together. The tightening movement can then be performed without danger of the wedges slipping round.

Title: Padded despatch bags prodn. - using two different tracks of material running through transverse sealing station, which are then folded and cut to size
Inventor: WEIMAR ALBERT ING GRAD
IPC: B31B170/20
Filed: 1976-07-01
Abstract: Production method for padded despatch bags consisting of an outer layer of paper and an inner layer of padding with the two tracks of material allowed to run together each coming from one supply roller, continuing together and then guided to a transverse sealing station. Here they are joined at the edges transverse to the longitudinal direction of the bag, following which the connected tracks are led through a length folding station where they are folded over along a longitudinal centre line which in each case forms the base fold of the competed bag. The combined material track thus prepared is then separated into individual bag cut outs having the required width at a separating station (15) and the padded foil is compressed through a rotating pressure beam prior to the separating cut.
