Title: Nuclear press vessel with external continuous polygonal prestressing - bearing at supports which are jacked radially outwards to tension cables
IPC: F16J12/00
Filed: 1974-07-12
Abstract: A pressure vessel, esp. for nuclear reactors, has the (cylindrical) wall prestressed by external, circumferential cables bearing against the vessel at intervals around its circumference so that the axial plan of a cable is polygonal. The length of a cable is fixed, apart from its elastic extension; the cables are tensioned by tensioning devices incorporated into each cable support, esp. by a removable jacking cylinder between the saddle, in which the cables rest, and the vessel wall. After the saddle has been raised by the jack it is locked in position, pref. by a pair of self-locking wedges or by self-locking screws. Accurately defined cable loads can be applied with ease up to almost any value. Retensioning is possible later, to compensate losses in cable load.

Title: Pneumo-percussive drill tool rotor - has tool ratchet indexed by rotor mounted pawl pairs controlled by air cylinders
Inventor: SUBAREW ANATOLIJ I
IPC: E21B1/30
Filed: 1975-08-22
Abstract: A sleeve inside the rotor carries hinged pressure activated pawls which engage a ratchet in the forward area of the drill where it is linked to the tool, to positively rotate this during drilling. Each pair of pawls (39, 40) in the sleeve (38) is rigidly connected on an axis parallel to the central drill axis so that the pawls point opposite ways per pair, and thus rotate the ratchet in these two opposing directions. Pressure is supplied from a compressed air cylinder (44) with piston (45) in contact with the pawls. The compressed air source is coupled up to the cylinders activating the pawls which point in one direction, as compared with the cylinders which activate the opposed pawls and are connected to atmosphere. This disengages the pawls from the tool-turning ratchet.

Title: Tunnel kiln regulated by fuel and air supply - to balance heat input rate and heat demand rate
Inventor: JESCHAR RUDOLF PROF DR ING
IPC: F27D19/00
Filed: 1976-01-21
Abstract: Regulation method of tunnel kiln is used for a kiln in which the temp. in the combustion zone is a monitored variable and the quantity of fuel supplied to the combustion zone is a regulated variable. The prod. of the mass flow of the gas flowing through the kiln and its specific heat is regulated so as to be equal to the prod. of the mass flow of the fired material and its specific heat. The quantity of fired material passing through the kiln may be determined either by measuring the mass supplied per unit time or by multiplying the quantity of fired material per wagon length and the average speed of the wagons. The mass flow of gas passing through the kiln is pref. determined by measuring the press. difference across an orifice plate, which gives a vol. indication, by reading the press. and by reading the temp. of the gas, esp. the supplied combustion air; these three readings are evaluated in a calculating device into which the specific density and specific thermal capacity of the particular gas (air) are supplied and are used to generate a signal which passed to a PI-controller, which in turn operates a motor to adjust the flow control valve for combustion air. As a variant, the extn. of gas from the tunnel kiln may be varied instead of the supply of air to the kiln. The quantity of fuel supplied to the kiln to maintain a continuous combustion process at uniform temp. is regulated to an optimum.

Title: Pneumatic conveyor for containers - has set of slot nozzles connected to blower at each open end of conveying pipe line
Inventor: FUTER RUDOLPH E
IPC: B65G51/02
Filed: 1976-06-02
Abstract: Equipment for pneumatic conveying of containers includes a conveying pipe line open at both ends for conveying air of low pressure and a conveying container of a slightly smaller cross section than the conveying pipe line. The wall of the pipe line near each open end has a set of slot nozzles which are spaced closely together and have a wider opening than depth. The nozzles are either diverting the conveying air from the conveying pipe line or are allowing a blown air to flow towards opposite open end. Each set of nozzles is connected by a branch line to a blower which is supplying a certain quantity of air to one branch line and is removing a certain quantity of air from the other branch line in order to keep the air pressure in the conveying pipe line higher than outside the open ends. When the container is transported through the conveying pipe line and the whole quantity of air is supplied to one and extracted from the other branch line no appreciable air movement takes place through the open ends in or out of the conveying pipe line.

Title: Cylinder lock for vehicles, buildings, furniture - has adjustable locked cams allowing alteration to accept alternative keys while preventing opening with skeleton key
Inventor: MILLETT JAMES A
IPC: E05B29/00
Filed: 1976-10-15
Abstract: The simple cylinder lock has a facility for instant adjustment without tools to accept alternative keys. The lock cannot be opened with a skeleton key. The cams (50) moving in slots in the cylinder (12) engage in cavities (52, 54) and are actuated by key followers (70). Rotation of the cylinder so that the key follower retaining piece (42) moves into the recess (46) releases the serrations connecting the cams (50) to the followers (70). In this setting insertion of an alternative key results in relative movement of cams (50) and followers (70) to conform to the code of the new key. Prevention of opening with a skeleton key is achieved by locking of the cams (50), affected by displacement of the rod (16) from its groove (18) by any small rotational movement.
