Title: Drill-clamping device for a grinding machine for small drills
Inventor: ARNOLD ERNST
IPC: B24B3/24
Filed: 1981-08-31
Abstract: The free end of a small drill (16), clamped in a collet chuck (10) and having a shank attachment, is supported against the grinding direction of a grinding wheel (34) by a supporting finger (14) which can be adjusted relative to the drill axis. Owing to the drill being supported, the risk of fracture, present when grinding against the drill, is virtually eliminated. In order to carry out a two-surface grinding operation, the drill (16) can, by pulling and rotating a changeover ring (26), be rotated through 180 DEG  about its axis without the supporting finger (14) thereby being pulled back. In a pivoted position of the entire securing means (12), the adjustment of the drill (16) and the positioning of the supporting finger (14) on the drill can be effected precisely under a microscope (38). <IMAGE>

Title: Railway line tamping machine
Inventor: JAQUET ANDRE
IPC: E01B27/16
Filed: 1978-06-29
Abstract: The tamping machine comprises a device making it possible to remotely control the amplitude of at least one operating movement of its tamping tools without requiring the presence of operators on the track. This device comprises:   - a detector (PVUB) of the position in height of the unit carrying the tamping tools; - at least one comparator (C1) transmitting a switching signal controlling the stopping or the reversing of a movement of the tamping tools; - an apparatus for adjusting (A1) the transmission level of this signal.   At least one comparator (CPR) is linked to its adjusting apparatus (A3) by a circuit for automatic correction (22, 23, 24, M1, M2) of the overshoots of the level displayed on the adjusting apparatus (A3). <IMAGE>

Title: Electrochromic display element
Inventor: HAMADA HIROSHI
IPC: G09F9/30
Filed: 1977-07-16
Abstract: In order to achieve a uniform contrast of the colour display in an electrochromic display cell, in which the area of the individual display segments (11) can vary, it is proposed to select the electrical resistance of feed electrodes (12) which are mounted on the substrate (1) and lead to the display segments (11) to be inversely proportional to the area of the respective display segments (11). This matched dimensioning of the resistance value of the feed electrodes (12) can be performed by suitable selection of the length dimensions and/or layer thickness dimension and/or area of the feed electrodes (12). <IMAGE>

Patent CH-612871-A5 (CH)
Title: Process for grinding parts by means of a flowable abrasive medium
Inventor: OHNO IETATSU
IPC: B24B31/00
Filed: 1976-08-20
Abstract: In the grinding process, the parts to be ground are introduced at one end of a container (1), which is circular-cylindrical or polygonal in cross-section, and thus come into contact with an abrasive medium (B). During grinding, one end of the container is held firmly (2) and the other end is moved (5) on a circular track, with the result that the parts to be ground move, in contact with one another and with the abrasive medium, in helical tracks along the inner circumferential surface (1a) of the container until they emerge at the other end of the container. This results in rapid and gentle grinding. <IMAGE>

Abstract: The machine chamfers the lower boards of standard pallets used for goods transport, having a table (3) accommodating the board, and two milling cutters whose axes are perpendicular to the table. Lengthwise guides are fixed to the table, and have two openings through which the utters can pass. A stop (13) is mounted at each end of the table, to retain the board (P1), which is moved with its lengthwise edge against the guides and in front of the cutters. The distance between the stops is such that the cutters form two chamfers in this edge of the board, leaving the central portion and two end portions intact.
Patent CH-695723-A5 (CH)
Inventor: RAEBER THOMAS
IPC: B24B7/13
Filed: 2002-02-21
Abstract: The invention relates to a device and a method for width-sanding sheet-type floor coverings and rubber printing bands that are uncoiled from cylinders and recoiled onto cylinders upon sanding. The material is repeatedly guided across a driven supporting roller and is continuously sanded on the opposite side thereof. According to the inventive device and method, the sheet-type material is sanded by means of a continuous sanding strip while being enveloped in part by the supporting roller. The inventive use of sanding strips results in a better sanding quality that is achieved in fewer sanding processes as opposed to cylinder sanding machines.

Title: Salt distributing machine - for meats esp ham
IPC: A23B4/02
Filed: 1971-12-03
Granted: 1973-07-27
Abstract: Mixing machine is intended for the homogeneous distribution of previously introduced salt into a mass of meat, esp. ham. The meat is held between an upper plate, attached by a cardan joint to the piston of a hydraulic cylinder, and two lower plates; these are mounted on stems which are given an up and down movement by a motor acting on cams. The alternating, vertical, non-synchronised movements of the lower plates result in an efficient distribution of the salt in the ham and the duration of the treatment can be much reduced. In a variant the cams may be replaced by vibration generators of a known type. The energy with which the meat is mixed depends upon its degree of compaction, as it acts as a deadener of the vibrations.

Title: Dye application plant - for skins and leathers
IPC: C14C15/00
Filed: 1971-12-16
Granted: 1973-08-03
Abstract: The conveyor, consisting of a band formed of a stretched grid, is arranged so that its lower, return strand passes through a bath filled with water. The conveyor brings the skins under a sprayer to a group of brushes mounted on a carriage which moves backwards and forwards at right angles to the conveyor. The brushes only spread the dye when they are moving in the direction of the edge of the skin. A control device raises them when they are moving in the opposite direction. A vacuum is provided by a fan with its inlet arranged in the brush zone, under the upper strand of the conveyor, the skins are thus held closely to the grid so any movement of the skins, under the action of the brushes, is prevented.

Title: Metal grille formed of perpendicular bars - has mounting slots extending partly through the bars
IPC: E04C2/42
Filed: 1973-10-16
Granted: 1975-05-09
Abstract: The construction of substantial metal grilles is described such as those placed over ventilation or lighting shafts and which are intended to support human traffic. Construction of the grille is by longitudinal elements (1, 4) slotted to half their width so that they may be mounted orthogonally to each other. To provide the necessary strength, the portions (5) between the slots are angled in a variety of ways and in particular, bending alternately in different directions increasing rigidity. Grilles constructed in this way need no particular fixing between the elements and are cheap because the elements are simple and may easily be mass produced.
