Title: Measuring profile of cylindrical object, esp. workpiece on turning machine - involves averaging surface position sensor outputs as workpiece is turned and moved axially whilst sensors move radially according to ideal profile
Inventor: TSUBOI AKIRA
IPC: B23Q17/20
Filed: 1992-01-16
Abstract: The method is for measuring the profile of a cylindrical object, whose radius varies with axial position.

Filed: 1992-10-24
Abstract: 2.1. Polyoxymethylene (polyacetal) is an excellent material from which, in particular, rigid articles can be produced in high accuracy. However, since polyoxymethylene is acid-sensitive, the object of the present invention is to provide a polyoxymethylene which has been stabilised towards acids. 2.2. By addition of from 0.01 to 5 parts of an alkali metal salt of a polybasic acid, for example oxalic acid or citric acid, and/or from 0.01 to 5 parts of a polyalkylene glycol, for example polyethylene glycol, and/or from 0.1 to 100 parts of a thermoplastic polyurethane, in each case based on 100 parts of a polyoxymethylene, the latter is stabilised against acid attack, where, in particular, the combination of an alkali metal salt, in particular of an oxalate, with a few parts of a thermoplastic polyurethane is advantageous. The weight loss of a stabilised POM can be less than 3% compared with non-stabilised POM on exposure to acid. 2.3.

Title: Axle assembly with locking mechanism
Inventor: IRIKURA KOJI
IPC: B62D11/08
Filed: 1993-07-27
Abstract: An axle locking mechanism, which is accommodated in an axle casing (19), forms part of an axle assembly for small, self-propelled machines of relatively simple construction. The locking mechanism comprises a left-hand and a right-hand rotor (47L, 47R), which are each provided with teeth (47a) and are fixed on left-hand and right-hand wheel axles (20L, 20R), and left-hand and right-hand locking elements (49L, 49R) each with at least one pawl (49a), which can engage in the teeth. The locking elements are supported on a control shaft (50), which runs parallel to the wheel axles so that the said elements are swivelled by a rotational movement of the control shaft in order to produce a locking engagement between the pawls and the teeth. In order to produce the locking movement of the locking element by the control shaft a torsion spring (53) is preferably used. The axle and the locking mechanism can be manipulated as a unified assembly in a self-propelled machine so that assembly of the machine is facilitated. The locking mechanism is closed off from the outside and is highly reliable and durable. <IMAGE>
