Title: Transducer regulated wheel balancing machine - has dynamic and optical measuring system for rotating shaft-mounted wheel
IPC: G01M1/02
Filed: 1976-09-01
Abstract: The wheel-balancing machine incorporates transducers mounted between shaft bearings and a support frame carrying a rotating shaft is rotated the wheel is mounted. The shaft is rotated by an electric motor and pulley belt transmission system. The transducers provide signals proportional to the out-of-balance forces detected in the shaft bearings. An optical arrangement for determining the wheel position consists of an angled mirror or prism (81) mounted on a sliding arm (82). The arm moves parallel to the shaft axis and is connected to a potentiometer to provide proportional electrical output. A parallel light beam can be reflected onto the edge of the wheel rim (80). The light reflected from the rim is used to determine the relative wheel position.

Patent FR-2337023-A1 (FR)
IPC: B29C44/12
Filed: 1976-12-30
Abstract: Two webs (1, 3) are bonded together in the process with the aid of a thin polystyrene foam sheet (2) by feeding the polystyrene foam sheet to a first web heated to at least 140 DEG C and adhering the sheet by means of a pressure roller pair (5', 5'') to the web material. Thereupon, this construction is subjected to post-heating to 160-200 DEG C by a post-heating surface (6), causing the polystyrene foam sheet (2) to form a film. Then the second web (3) is applied to the film-coated side of the first web (1) and fed to a pressure roller pair (7', 7''). The two-layer web (9) thus formed is then cooled in a cooling device (8). The process makes possible the full-surface bonding of webs of materials of the same or different kinds in a simple manner and at high operating rate.

Title: Conical yarn support - for uniform dyeing, which nests or stacks with others of its kind
IPC: B65H75/20
Filed: 1977-02-10
Abstract: A yarn support comprises a conical dyeing former, capable of nesting or stacking into columns for dyeing the yarn. The walls of the cone support are perforated with holes to allow the dye liquor to circulate. Stacking is effected by the annular cut-out portion in the base of the cone body which is capable of joining or nesting with the upper end of another cone support. The cone support provides a method of joining or stacking which remains unaffected by high pressure dyeing or turbulent conditions, and ensures good distribution of the dye liquor through the yarn.

Title: Electromagnetic and mechanical strong room door blocking mechanism - has link operated pivoting cam moving armature onto magnet
IPC: E05B47/00
Filed: 1977-03-08
Abstract: The combined mechanical and electromagnetic blocking mechanism may be used on a strong-room lock. The armature (3) is moved onto the electromagnet (2) mechanically, ie. a link (6) associated with the bolt-cage (5) rotates a cam (4), then the electromagnet (2) is energised to lock the armature (3). The arrangement reduces the electric power required to energise the magnet (2). The armature may slide within a sleeve (10) with its movement in opposed directions limited by a flange (30) and the magnet (2) respectively. Movement of the bolt-cage (5) into the closure position pivots the cam (4) until a rounded apex (40) engages and displaces the armature (3) onto the magnet (2). The magnet (2) is now energised and the bolts (5) are effectively blocked at closure. The mechanism may include a reverse bolt (52) which interposes the magnet (2) and the armature (3) when the bolts are withdrawn. When the magnet (2) and the armature (3) are locked together, the later (3) impedes the reverse bolt (52) and prevents bolt (5) withdrawal.

Title: IC engine starter motor engagement drive - has coarse threaded free wheel coupling to ensure pinion engagement
IPC: F02N15/06
Filed: 1977-05-31
Abstract: A roller bearing free wheel (27) is arranged between the starter motor drive shaft (12) and the starter pinion driving shaft (40). The free wheel inner ring (34) is fitted on a coarse threaded section of the pinion driving shaft and the outer ring is in mesh with a straight spline (25) carried by a cover (17) fixed to the motor shaft (12). The outer free wheel ring has a projection (28) containing the engagement spring and is subject to forwards thrust by the magnet push rod (53). Should the pinion strike the fly wheel ring on the tooth, the magnet continues to exercise forwards thrust to push the roller free wheel (27) opposite to the pinion shaft (40). The free wheel then turns on its coarse thread (41) allowing the stater pinion to turn and engage fully. The starter motor is energised by a relay only when the pinion has fully engaged.
