Patent CH-664593-A5 (CH)
Title: Wooden post protective disc - has concentric sawtooth section ribs on underside pressing fibres towards centre during hammering
Inventor: CARRARD CHARLY-ARMAND
IPC: E02D13/10
Filed: 1985-10-18
Abstract: The protective disc is for use when hammering wooden posts home, its bottom face comprising concentric ribs (3) of sawtooth section turned towards the outside. These are driven into the wood and press its fibres towards the centre, at which there is a small hole (4) in the disc, with a deep counterbore (5) extending from the top face. This allows the disc to be temporarily secured to the post by a small nail. USE - Protects post from splitting during hammering home, while counterbore gives enough free movement to allow easy removal of disc afterwards.

Title: Process for the preparation of glucose/fructose mixtures from cereals
Inventor: MUELLER HANS
IPC: C13K11/00
Filed: 1975-06-12
Abstract: In the preparation of glucose/fructose mixtures from cereals, the crude cereals are directly subjected at elevated temperature to an enzymatic degradation as far as glucose and, after removal of concomitant substances, the glucose solution is enzymatically isomerised to a mixture of glucose and fructose. Before the isomerisation, the calcium ions added for the enzymatic degradation are precipitated by passing carbon dioxide in at pH 8 - 10. Complete removal can be effected by use of ion exchangers.
Patent CH-608633-A5 (CH)
Title: Halftone photoengraving method
Inventor: HOMMA KOKICHI
IPC: G03F5/20
Filed: 1974-07-08
Abstract: A photosensitive carbon paper (21) is exposed by contact, in any order, with a transparent-line screen (frame) (20), with a halftone positive for photoengraving, planographic or relief printing and with the same positive, but the latter being equipped with a diffusing sheet sandwiched between the positive and the carbon paper, after which the latter is transferred to a gravure cylinder and the development of the paper and the etching of the cylinder are carried out in the usual manner. This method is simpler compared to the known method called "double positive" method, whilst keeping its advantages. During the exposure of the carbon paper through the transparent-line screen (frame), it is advantageous to superpose onto the screen (frame) either a continuous-tone negative (19) of the same subject to be reproduced or a halftone negative (23) lined with a diffusing sheet (24). Undesirable moiré effects are thus avoided. <IMAGE>

Title: Automatic rifle breech bolt with rotating guide - has sliding block with releasing mechanism and stop actuated by gases (OE150575)
IPC: F41A3/26
Filed: 1974-12-30
Abstract: The breech bolt for automatic rifles reciprocates in breech housing and it is provided with a guide cam for rotation. This rotation is used to hold breech block in cartridge chamber during firing and for releasing. The housing forming obstruction to rotation is eliminated and a weaker breech bolt spring can be used.

Title: Fluid press. assisted piston ring seal - uses fluid passage through piston rod to pressure space behind seal
IPC: F16J15/46
Filed: 1973-03-30
Granted: 1974-10-25
Abstract: Sealing is effected by a square-section piston ring pressing against a cylinder bore. This low friction material seal, housed in a deep narrow groove in the piston, is 'backed up' internally by a rubber O-ring itself subject to fluid pressure admitted at the bottom of the groove, the fluid is supplied through a passage in the piston rod. Since this pressure is made greater than that of the liquid ahead of the piston no leakage occurs. A similar arrangement may be used to seal the piston rod. Finds application to static, sliding or rotating seals.
