Abstract: 1438313 Fans PAPST-MOTOREN KG 22 Nov 1973 [23 Nov 1972] 54309/73 Heading F1C [Also in Division H2] A fan comprising a rotor 2 and stator 1 is characterized by a fan wheel 25 of plastics material being secured to the rotor in the axial and circumferential directions by deformation of parts of a wall 35 of the rotor in regions where the fan wheel is provided with recesses 36, the deformation taking place subsequent to the locating of the fan wheel on the rotor. Fan blades 26 are supported on the wheel, which is re-enforced by fillets 28, and spaced from the rotor by a distance h. The blades are spaced from the casing by a distance d (2d<h<3d). A baseplate 4 carries a sleeve 3 on which is mounted the stator 1. The sleeve supports a rotatable shaft 20 to which is connected the rotor 2 via disc 23. The shaft 20 rests on a disc 9 which is able to flex by a distance S, Fig. 5 (not shown). A series of bores 33 are provided in the rotor and communicate with a continuous annular groove 34. During electrodynamic balancing of the rotor weighting lead is inserted in the groove 34. Pressure surges and noise are reduced by a projection (39) at the outlet (17) of the fan Fig. 1 (not shown). The invention is also applicable to axial-flow fans. The motor may be cooled by an additional airstream passing to the inlet through stator grooves 13 from the outlet 17, Fig. 4 (not shown) has bores (82) in the lamination pack for cooling air.

Abstract: 1303197 Press for powdered material SINTERMETALLWERK KREBSOGE GmbH 16 Nov 1970 [9 Jan 1970] 54470/70 Heading B5A A press tool 2 (Fig. 1) for manufacturing from powdered or granular material tyre spike socket blanks 1 having an enlarged head 5 and a tapering recess, comprises a die 3, a first plunger 8, a second plunger 9 carrying a mandrel 10, and an extractor 12 (Fig. 3) for aiding separation of a socket blank from mandrel 10. The mandrel 10 (Fig. 1) is rigid with an end face of the second plunger 9, a curve 11 being formed at their intersection. A number of press tools 2 are supported by an intermittently rotating turntable A (Fig. 3). At an extracting station, the plungers 8, 9 (Fig.1) are raised to lift a blank 1 from the die 3. Further turntable rotation moves the blank 1 between fixed parallel rails 13, 14 (Fig. 3) the sloping ends 15, 16 of the rails serving to axially withdraw the blank 1 from the mandrel. In an alternative embodiment, the ends 15, 16 of the rails are not tapered, and the plunger 9 is lowered to remove the mandrel 10 from the blank 1. The rails 13, 14 guide the blanks 1 on to a conveyer belt leading to a straight-through sintering oven, or to a collector that feeds the oven. In an alternative embodiment, a press tool 2 may be stationary, and the extractor 12 reciprocated.

Title: Shift register comparator having failsafe qualities
IPC: G06F7/02
Filed: 1969-11-10
Abstract: 1,242,974. Comparators. WESTINGHOUSE ELECTRIC CO. 10 Nov., 1969 [3 Dec., 1968], No. 64841/69. Heading G4M. [Also in Division H3] Serial pulse trains A, B in which words are encoded using a "comma-free" code with a predetermined minimum frequency of alternation between 0 and 1 bits are shifted into respective registers 12, 14 and corresponding pairs of bits are compared in stages 22a-22f, each of which comprises an upper and lower transmission path 26a, 25a for the output of an A.C. generator 16, each path including a pair of series-connected power switched A.C. amplifiers such as 27a, 28a controlled by the outputs of the associated register stages FF such that the upper or the lower path in each stage is only completed if the associated pair of bits correspond. The amplifiers 27a &e. Fig. 3 have an A.C. input to a base drive circuit 50, e.g. a transformer which performs a D.C. blocking function, has a fail-safe characteristic and is arranged to overcome the forward conduction threshold of transistor 44 only when the A.C. input level is not below the normal output level of generator 16. The output of the amplifier is taken from an attenuator 52, e.g. a transformer, which reduces the gain to unity so that the same threshold level is applied in each amplifier. Power switching of the amplifier is performed by circuit 36a. A positive 1 bit on input 59 e.g. from the Q output of FF1<SP>1</SP> turns on transistor 54 so that point 58 becomes positive and capacitor 60 is charged via diode 64 which clamps power output P to earth so that transistor 44 does not conduct. An earth level O bit on input 59 turns on transistor 56 so that point 58 is earthed and the output P goes negative to allow conduction of transistor 44. Capacitor 60 is chosen so that if a 0-1 transition does not occur within the maximum allowable interval, e.g. 5 bits, the charge on it falls to a level below which transistor 44 does not conduct. Fail-safe operation is ensured if generator 16 fails or if one of the register stages freezes in either state or if the minimum allowable 0-1 transition frequency is not maintained.
