Patent DE-2727620-A1 (DE)
IPC: F26B15/12
Filed: 1977-06-20
Abstract: The apparatus comprises a driven pintle chain (1) and a transport chain (3) which move at approximately equal height, parallel to each other and at a contact-free distance apart, along a common path section. The transport chain is equipped with centring apparatuses (5) arranged to be rotatable about their own axis, at the same distance apart as the pintles (4) of the pintle chain (1), and provided with gripping jaws. On the common path section, the pintles and the centring apparatus each move in such a manner that they are approximately opposite on a common axis. Furthermore, means (15, 17) are attached for conveying the hollow bodies from the pintles (4) to the centring apparatuses (5) and from the latter to the pintles. A control roller is connected via a cam (12) to gripping jaws of the centring apparatuses (5), in order to close and open the latter. A drive (13) serves to rotate the centring apparatuses, while a coupling, which can be switched off, is provided between the pintle chain and the transport chain to drive the chains in the same direction and in a synchronised manner over the common path section. <IMAGE>

Title: Single cell protein and fat mfr. by cell cultivation - using medium of vegetable starch liquefied by amylase
Inventor: NOJIRI MICHIHIKO
IPC: C12N1/16
Filed: 1977-06-23
Abstract: Single cell proteins and fats are prepd. by: (1) liquifying vegetable carbohydrate (starch) by treatment with liquifying amylase; and (2) culturing microbes which can produce single cell protein and/or fat; while simultaneously saccharifying the liquified starch soln. with gluco-amylase. A large amt. of raw material can be treated in higher concn. than other known methods. Operation and automation of the process are easy. Liquifying process is performed at 80-92 degrees C for 30-90 mins. The medium used for simultaneous culturing and saccharifying should contain sugars (1-8%, generally 4%), and other nutrient components such as N-source phosphor source, Mg and K. The cultivation is carried out at pH 3-7 and 30-45 degrees C while simultaneously saccharifying with gluco amylase.

Title: Piston for motor vehicle air conditioning compressor - has valve lift limiting ring with insert to reduce dead volume
Inventor: HINTZE RUDOLF
IPC: F04B39/00
Filed: 1977-08-03
Abstract: The compressor has a piston (1) reciprocating in a cylinder (4). The suction valve (7) is fixed in the crown of the piston and gas enters from the crankcase. The piston has an upstand ridge round the valve and a ring (8) is fixed at the outer end of this ridge. It meets the edge of the valve plate (7) as the valve opens and so limits the lift of the valve at high engine speeds. The discharge valve (15) is clamped between the cylinder head (3) and the cylinder (4). An insert (17) on its underside projects into the space above the suction valve inside the lift limiting ring (8) when the piston reaches TDC. This prevents the lift limiting arrangement from increasing the dead volume.

Title: Electroslag remelting plant - using two electrode holders, each mounted on a swivel arm for rapid electrode replacement
Inventor: PATON BORIS E
IPC: C22B9/18
Filed: 1977-12-13
Abstract: Plant for the casting of ingots by electroslag remelting, where consumable electrodes are successively fed into the mould. On each side of the mould is a pillar on which a trolley can be driven vertically, and each of the two trolleys has a horizontal pivot shaft for a lever arm. The end of the arm has a higned mounting for an electrode carrier and the arm can be driven in an arc in a vertical plane to move an electrode onto the axis of the mould. When the lever arm locates an electrode on the mould axis, the arm is pref. in contact with a plate feeding electric current to the electrode, and a supporting bracket holds the arm when an electrode is replaced. In one pref. plant a sensor indicates the presence of the lever arm in its working position, i.e. when an electrode is on the mould axis. As soon as one electrode has been consumed, it can be swung by its lever arm away from the mould axis so a new preheated electrode can be moved into the mould via the second lever arm.

Title: Active bow rudder for yachts and ships - has engine-driven water pump feeding nozzles facing sideways and remotely operated valves for pressure and quantity control
Inventor: DAHM HERBERT
IPC: B63H25/46
Filed: 1978-01-12
Abstract: The active bow rudder for yachts or ships involves a pump driven by the propulsion engine supplying ambient water under pressure to a transverse pipe near the bows feeding nozzles either side of the centreline, in the submerged part of the hull. The pump suction line includes a strainer. Flow quantities and pressures in the system are controllable by remotely, pref. pneumatically, operated valves at inlet to the suction line, in the lines to the bow nozzles and in a bypass line from pump discharge to suction. The sideways thrust of the nozzles gives the sudden effect.

Title: Subterranean gasification of coal - using matrix of bore-holes for charging gasification agent and discharging prods., minimising costs
Inventor: WENZEL WERNER PROF DR ING
IPC: E21B43/247
Filed: 1978-04-24
Abstract: The subterranean gasification of coal incorporates defining the limits of the coal masses in layer by imaginary lines and offsetting the boreholes, by which the gasifications agent is introduced and by which the gaseous products are discharged, w.r.t. the coal front at which the reaction is taking place, in the direction of progression of the gasification. The corresp. feed and discharge holes are at a distance from one another in a direction perpendicular to the progression of gasification, so that the gasification agent circulating from one to the other is in contact with the coal mass. The gasification agent is e.g. air, O2, H2, CO2 and/or steam. The costs of preparing and exploiting the coal layer are minimised. Gasification is possible independently of the disposition and thickness of the layers, and in the case of horizontal as well as inclined layer. A less dense system of pipes is needed than with other installations; the surfaces are less covered and can be used for agriculture. Gasification under high press. e.g. 10-60 bar is possible and gives good contact, partic, useful in the case of coals which are difficult to gasify.

Title: Disc-type typewriter mechanism - has hammer lever coupled by tension spring to lever acting against disc stop
Inventor: KERZEL GUENTER
IPC: B41J1/24
Filed: 1978-12-18
Abstract: The typewriter mechanism comprises a disc with elastic ribs on which the characters are mounted, these being caused to strike the paper on the platen by a power operated hammer working with an elastic component and whose energy is restricted dependent on the surface area of the character. The elastic component is formed by a system of levers on a fixed axis, coupled at one end to the hammer, and engaging at the other on hammer movement with one of several stops on the disc. These stops are at varying distances from disc axis, dependent on the character surface area. The lever system comprises a lever (39) coupled to the hammer (43), and in turn coupled by a tension spring (33) to a stop lever (21) swinging against a stop (17) on the disc (1). The spring is so mounted that when the second lever (21) strikes the stop, the first one (39) lifts clear of a supporting face (37) on it, simultaneously increasing tension in the spring.
