Inventor: FARB NORMAN EDWIN
IPC: B41J29/377
Filed: 1988-07-01
Abstract: In a selective printer of the kind having a hammerbank shuttle which is linearly reciprocated across the paper during printing, the hammerbank is reciprocable within an elongate plenum supplied with cooling air, and apertures in the hammerbank itself admit the air to electromagnetic components within the bank. As shown in cross section in Fig 13, the hammerbank 18 is reciprocably supported on shaft 82 within plenum 272. Hammersprings 16 are retracted against their natural resilience by a permanent magnet 132 between respective pole pieces 126, 128, and are released for printing when respective coils 136, 138 are energised to negate the influence of said magnet. Cooling air is directed over said coils via apertures 282, 284 and chambers 292, 288 in the hammerbank, these being so disposed as to create significant turbulence so as to maximise cooling. Air is constrained to pass between the coils rather than to leak through the interstices between springs 16 by configuring the coil bobbin flanges 134 to act as an air dam. The following matters are also disclosed:     (a) the magnetic arrangement of the hammerbank   (b) the mounting arrangement of the hammerbank   (c) the attachment of springs in the hammerbank   (d) casing arrangements for the printer   <IMAGE>

Patent DE-3836576-A1 (DE)
Title: Adjustable belt pulley
Inventor: MOELLER REINHARD ING GRAD
IPC: F16H55/56
Filed: 1988-10-27
Abstract: Such an adjustable belt pulley has two disc flanges which are seated on a shaft or hub and are displaceable axially with respect to one another and which receive a belt between them. At least one of these flanges is connected to the shaft or hub via polygonal profiles projecting radially above the surface of the shaft or hub and is mounted thereon by means of a centring inner sliding bearing. The rotatory and tilting forces occurring are to be kept as low as possible and, at the same time, are to be distributed to different faces, each large. For this purpose, the polygonal profile serves solely for transmitting the torque, whilst the inner sliding bearing is dimensioned in terms of its length and rigidity as well as its tolerances, in such a way that the tilting forces are diverted completely via this, without being supported on the faces of the polygon.

Title: Air bladder for forming uncured tyre profiles - where bladder reinforcement with continuous radial cord layer and shorter cord layers in centre forms broad tyre profile
Inventor: YOSHIE ATSUYOSHI
IPC: B29D30/26
Filed: 1990-02-21
Abstract: A reinforcedforced rubber bladder (B) is described which forms uncured tyre constructions. At least one layer of reinforcing cord stretches the full width of the assembly and is embedded in a rubber matrix. One or more shorter layers of cord are embedded in the central area which corresponds to the tread area of a tyre. The cords in the central area can form an angle to the axis of the bladder. Such a construction prevents excessive deformation of the tread area but allows the side walls to be expanded to create the usual tyre shape. Cord layers prevent deformation of the bladder with repeated use and restrain the load imposed on the machine. Uniformity of expansion is achieved and distortion avoided. USE/ADVANTAGE - (B) is used in the second stage of a radial tyre process. (B) retains the original shape after continuous cycling. Suppression of expansion in the central area is not solely achieved by thicker walls. (B) ensures a greater degree of flatness in the tread region.
