Abstract: Ein Schleuderrad für Schleuderstrahlmaschinen besteht aus zwei rotierenden durch Distanzstücke (5) auf Abstand gehaltenen Radscheiben (3, 4) und einer Mehrzahl von gleichmässig über den Umfang verteilten mit Seitenleisten (15) versehenen, in radialen Nuten (16) der Radscheiben (3, 4) von innen einschiebbaren Schleuderschaufeln (6), welche in radialer Richtung nach aussen durch feste Anschläge (30) gehalten werden. Die Länge der Seitenleisten (15) der Schleuderschaufeln (6) ist kleiner, als der Durchmesser des von den inneren Kanten (22) der Schleuderschaufeln (6) gebildeten, zentralen freien Raumes (7) des Schleuderrades. Ausserdem ist die Breite (19) des über die Seitenleisten (15) hinausragenden Teiles der Schleuderschaufeln (6) kleiner als die freie Distanz (20) zwischen den beiden Radscheiben (3, 4). Durch diese Abmessungsabhängigkeit kann jede Schleuderschaufel (6) in einer zur Schleuderradachse verdrehten Lage von aussen zwischen den Radscheiben (3, 4) eingeschoben werden, bis sich die Seitenleisten (15) im zentralen freien Raum (7) befinden und dann von innen her in den Nuten (16) der Radscheiben (3, 4) bis zu einem festen Anschlag (30) zurückgeschoben werden, wodurch beliebig lange Schleuderschaufeln (6) verwendbar sind.

Abstract: The invention relates to thermally insulating, fire resistant material and its production.A problem associated with fire resistant material comprising refractory material and a binder is the tendency, in use, of the material to disintegrate due to bond failure. In the invention, hollow particles of a glass or of a ceramic are combined with a binder to give a material where the proportions of binder are such that the material is capable of deformation at high temperatures (e.g. up to 1100°C) without fracture or loss of cohesion. A specific example consists of 93% by weight of hollow spherical particles of pulverised fuel ash and 7% by weight of sodium silicate binder. The material is particularly useful in the protection of steel structures.

Abstract: The invention relates to a protective arrangement for a power transistor switch in a brushless type electric motor traction drive used in lift trucks. The power transistor switch (PS) (which may comprise a plurality of paralleled power transistors PS1-PS7. Fig. 1), supplies power to a DC series electric traction motor (M) and is regulated by a train of control pulses from a pulse width modulation control (PWM) to selectively vary the speed of motor (M). The conduction limit protective arrangement of the invention automatically changes the conduction limit for transistor switch (PS) as a function of the voltage, current and temperature conditions to which switch (PS) is subjected so that it is within its safe operating area at all times, thereby permitting switch (PS) to carry maximum current while being fully protected at all times. When power switch (PS) experiences abnormal current, timing capacitor (C1) is charged at a rate dependent upon (VCE) across switch (PS), and when the voltage on (C1) exceeds the fixed threshold value, comparator (COMP 1) provides an output signal to gate (NAND 1) which is opened in response thereto to turn off predriver transistor (PRD) and thereby remove the control pulse from switch (PS). 
     Consequently, if power switch (PS) experiences abnormally high on-voltage, it is turned off after a time interval which is a function of its collector-to-emitter voltage.

Abstract: The technique for transmitting address information between a processor (10) and a plurality of memory subsystems (14, 18) in a common bus (4, 6, 8) communication system (2). The width of the address field is greater than the number of lines on the bus (6). For example, addresses are three bytes wide, and the bus (6) is one byte wide, thereby reducing the number of pins required on the processor and the subsystems. For communication between the processor and a given memory subsystem, only those bytes of a selected address which differ from the corresponding bytes of a previous address are transmitted sequentially for accessing a selected memory location.

Abstract: The device for transporting bulk material has, on the outside of its casing (1), an inlet device (6) which rotates with the propeller (2) and which comprises one or a plurality of blades (5, 5'). A driving surface (11) of a segment (9) of such a blade (5, 5') sets the material into a rotary motion. A curved transporting surface (12) of the transporting segments (10) preceding a driving segment (9) supplies the product to the propeller (2). The radial distances of the surface elements from the transporting surface (12) to the rotation axis (8) increase, preferably continuously, in the direction of the propeller (2). Thereby, the transporting surface (12) is provided with a bevel along which the product moves in the direction of the propeller (2). The output rate of the transport device may be increased by input segments (16; 18) connected to the transporting segments (10) and by additional propellers (19) which move in the casing relative to the propeller (2). An embodiment with a single blade is very efficient in a number of applications.

Abstract: A laryngoscope (10) includes a tubular laryngoscope blade (12) which is curved in the manner shown in Fig. 2 and provided with a slot along its length. The blade is tubular throughout its entire length except for an end tip (20) which serves to elevate the epiglottis of a patient when the blade is inserted into the pharynx and larynx of the patient. The tubular and slotted nature of the blade permits an endotracheal tube to be inserted in an open end (22) of blade (12) and to be guided along the blade so that the tube can emerge near tip (20) after the blade has been inserted into the throat of a patient. This allows the tube to enter the patient's trachea for intubation as is well known. The tube is curved to permit it to follow the conformation of the throat and to facilitate insertion of blade (12) into the throat prior to intubation. The blade could also be of a material which is normally rigid but can be flexed or shaped to fit different throat configurations. A laryngoscope handle (25) containing a battery for energizing a light source can be coupled to base member (24). The light source may be located in the handle or in the base member. Light passes via fibre optic guides (46) into the larynx which can be viewed via eye piece (78) and fibre optic guide (74).
