Abstract: The invention relates to a method and circuit arrangement for magnetic recording of a digital data signal composed of a set of transitions. A recording signal is formed by superposition on the data signal of a high frequency, constant amplitude, magnetic biasing signal Sp. The biasing signal is phase-modulated relative to the data signal transitions. The invention remedies "peak shift" and can be applied to any rectangular or sinusoidal biasing signal.

Title: IC engine with fuel injection - has specified angles between injection channel pairs to direct vapours to opposite sides of chamber
Inventor: IVANCHENKO N N
IPC: F02B23/06
Filed: 1982-05-28
Abstract: The engine cylinder head is fitted with fuel injection offset from the throat area in a conical combustion chamber. To ensure uniform mixing and combustion, the angle (gamma) between the axes (15,16) of a pair of adjacent injection jets (10,11) directed onto the chamber and projected onto the cross-sectional plane of the chamber (4) should be 1.8 to 2.2 times the angle (delta) formed by any pair of adjacent jet axes directed onto the opposite chamber wall (6,4). As air whirls inside the chamber, fuel is injected through the channel system (10-14) along axes (15-19) to contact the wall at arrowed points (20-24). The radial air flow intersects the fuel jets at given angles move atomised fuel to the chamber centre. The jet tips remove combustion products by sweeping them round to the throat (7). In the expansion phase the fuel vapours are deflected towards the unused chamber air on the opposite side so that the air supply is totally utilised.

Abstract: The invention relates to a clamping device for firmly clamping a plate, primarily the mounting plate of an adjustable-height vice, with respect to a supporting column. Known methods for firmly clamping the supporting column often lead to snug, flat contacts between clamping pieces and the supporting column not occurring if specific production tolerances are exceeded. The damage resulting from this, as a consequence of a linear contact, is avoided according to the invention in that the clamping piece can be arranged with a recess, which is matched to the circumference of the column, precisely opposite the apex of a through opening, provided in a profile, for the column, and can be pressed against the supporting column by means of an eccentric shaft, which is self-locking. The avoidance of the risk of a linear contact which is achieved in this way permits high contact pressure forces which are achieved in that, for the purpose of clamping, the clamping lever must always be pulled upwards from a position pointing downwards, so that the clamping forces can be applied.

Abstract: A wheelchair is disclosed in which a body support frame pivoted to a main frame can move from a seated posture to a stand-up posture and vice versa without using an external elevating force. The wheelchair includes the main frame for supporting driving wheels and auxiliary wheels and a body support frame formed by interconnecting a lower limb support member, a waist support member and a back rest member to one another. The forward portion of the main frame and the tip portion of the waist support member are turnably supported by a pivot, and an extension member for turnably supporting the waist support member with the pivot as the support point is interposed between the main frame and the waist support member. The motive force for the stand-up operation of the body support frame relies upon the push-up force of the user of the wheelchair (the body lift-up force of the user by his or her upper limbs) and the force of the extension member.

Abstract: In a dry paper machine, in the step following the forming section, the fiber web has been conducted with the aid of topside and/or underside wires through the machine to the purpose of adding, drying and polymerizing the bonding agent. The unbonded fiber web has low strength and requires careful handling so that it might not break and cause process shut-downs. This circumstance has in modern paper machines resulted in a running speed which is low compared with the theoretical capacity of the machines. It has been found that web breaks tend to occur at the so-called open draws of its carry-through path, where the fiber web is not supported and is allowed to hang free in the air or carried by a wire (2, 3, 9). The object of the invention is to avoid open draws and to convey the web (1) in supported fashion through the entire process. The reliability of the procedure is improved by placing the mechanically drying calendering to be the last treatment step before polymerizing.
