Title: Steering system for road rollers - has steering cylinder pivoted on chassis for automatic straightening (SW210676)
Inventor: STURESSON RUNE
IPC: E01C/
Filed: 1975-12-05
Abstract: The steering system for selfpropelled tandem road rollers actuates rollers which can be pivoted on a common chassis. At least one roller is power driven, and the rollers follow a steady track on changing the direction of travel. The steering mechanism has a cylinder which rotates the roller frame in both directions at equal speed. The steering cylinder (11) actuated by a pressurised medium is pivoted at its mid length on the road roller chassis (1) by a self aligning bearing (15) which accommodates angular deviations. The piston rod (12) which passes through the cylinder (11) connects the front and rear frame of the rollers.

Title: Surveillance technique for natural or artificial structures - uses detection of acoustic stress pulses in structure, converted to electric signals
Inventor: ROBINE GERARD
IPC: G01N29/14
Filed: 1976-03-17
Abstract: A surveillance technique is described for natural or artificial structures such as sites or works of art. Acoustic stress pulses are sensed and detected on or in one or more structural elements. These acoustic pulses are transformed into electrical signals which are filtered so that only those pulse components lying within a know frequency band are transmitted. These components are converted into peaks whose level crosses the mean level of the corresponding components. Only those peaks whose levels are greater than a predetermined threshold are transmitted. The transmitted peaks are counted periodically to determine their rate.

Title: Multipurpose muscle exerciser with guided counterweight - has weight-bearing carriages sliding between parallel columns
IPC: A63B21/00
Filed: 1976-04-22
Abstract: Multi-purpose muscle exerciser comprises counterweights mounted on carriages which move between parallel columns by means of four nylon pulleys. The weights are thus maintained perfectly within their columns, and the pulleys allow smooth quiet running of the appts. In an example, the appts. comprises a frame of square-section tubes within which the columns are fixed by stays. The carriages consist of rectangular frames on which are welded supports for the pulleys. The weights are strung onto the central tube welded vertically to the bottom of the carriage, and stacked to obtain the desired load. To the top centre of the carriage is welded a half-ring for fixing a traction cord. The pulleys receive traction cords fixed to the carriages at one end and to traction bars at the other end.

Title: Bolt cold-heading machine - with four rotors for shearing, die, prepress and finish press tool holders
IPC: B21J9/06
Filed: 1976-06-25
Abstract: A cold-heading machine for the continuous production of bolts and screw blanks uses four parallel rotors which cooperate in contra-rotating pairs. The first rotor accepts a piece of wire which is sheared off a length and transfers it to a second rotor with a die. A third rotor contains a prepress tool and the fourth a finish press tool in which the tools are actuated by cams. This machine has a greated capacity and runs more quietly than reciprocating cold-heading machines. It is capable for more complicated blanks which necessitate an ejection stroke.

Title: Drive box for reciprocal chain - has pawl spring loaded between links but released to reverse drive upon excess chain tension
IPC: F16G15/00
Filed: 1976-07-02
Abstract: The box has slots at each end near the lower edge which allow the chain links to pass through. A swinging pawl is suspended from a pin near the upper part of the box. The pin is mounted on sliding brackets which are pushed downwards by the compression springs so that the end of the pawl is forced into the gap between a pair of links. If the tension on the chain is excessive the force of the springs is overcome and the pawl swings towards the other end of the box, releasing the chain, but ready to take the drive in the reverse direction if required.

Title: Short wiper arm for headlamp - with stamped tag for spring attachment fitted in aperture of arm channel
IPC: B60S1/34
Filed: 1976-07-09
Abstract: The short wiper arm for the small windscreen or for the headlamp has a mounting head (10) fitted to the wiper stub and a U-shaped arm (12) into which the end of the flat wiper arm (14) is pressed. A stamped tag (21) under the U-shaped arm serves as one mounting point for the spring (23) so that the short spring can provide an effective pull on the wiper arm.

Title: Pivoted hammer crushing mill - has hammer pivot offset to one side of centre line to provide tangential crushing action and reduced wear
Inventor: CLEMENT GEORGES
IPC: B02C13/28
Filed: 1976-10-14
Abstract: The crushing mill uses pivoted hammers to provide the crushing action on the material (6a). Their pivots (5a) are offset to one side of the centre line of each hammer (3a) to provide a tangential action and reduce wear on the working edge (4a). Each hammer has two pivot holes, these enabling it to be reversed and a new working edge is them used; both pivot holes are positioned identically. In use, centrifugal force positions the hammer so that its centre line through the two holes is in line with the centre (1a) of the rotating driver. True tangential working results with no out-of-balance moments.
