Title: Brake force distribution in motor vehicles
Inventor: STUMPE WERNER
IPC: B60T11/34
Filed: 1984-03-29
Abstract: To ensure that front wheels lock before rear wheels in a motor vehicle with or without ALB (automatic load-dependent brake force regulation), the rear axle brake force is held back in the lower range of brake pressure (range of small and minimum braking operations), so that the braking action at the rear axle is reduced or entirely eliminated. This corresponds to parallel displacement of the brake force distribution curve I to I1 in the brake force graph (Fig. 2) with the simultaneous retention of effective participation of the rear axle in the braking operation at average and high brake pressures. Fig. 5 shows a form of pneumatic relay valve having a spring 17 to hold back opening of a triple valve until the control pressure reaches a set value. <IMAGE>

Title: Weapons training simulator
Inventor: LACINY RICHARD WENCESLAS
IPC: F41G3/26
Filed: 1985-03-23
Abstract: In a weapons training simulator, laser radiation is output via optics (28) to simulate the firing of a round, and reflected radiation received via a conjugate path to assess the effectiveness of the shot. In the event of a miss a scan of the target area is required to provide fall of shot information. The scan is performed by controlled movement of the output faces of fibre optics (23, 24, 25) flexibly coupling to fixed sources (20, 21. 22) and of the input face of a fibre optic (200) flexibly coupling to a fixed detector (201). The problem of the bulk and inertia of prior art systems is improved by the remote location of lasers, drive and control, which may be conveniently separated for service or replacement without disturbing the optically aligned input and output faces. A further improvement is that vertically aligned multiple sources may be employed without undue weight penalty, yielding elevation information from a lateral scan.

Title: Method and equipment for juxtaposing handed articles
Inventor: COOLING HELEN MARIE
IPC: G09B19/00
Filed: 1985-11-12
Abstract: Children can see which way a picture "points" before they are old enough to read or interpret legends like "L" and "R". Children are less able to distinguish, by shape alone, which shoe belongs to which foot, and marking them "left" and "right" will not help. Accordingly, footwear (12) (13), or any other handed articles such as gloves or cutlery, is provided with devices (10) (11) which can be interpreted by the non-literate. By telling the child that the "dogs" (10) (11) like to face one another and do not like to be back-to-back, putting on shoes becomes a game and the child becomes self-sufficient in this respect at an early age. Unless provided during manufacture of the foot-wear (12) (13), the devices (10) (11) may be on labels or badges subsequently affixed, as by adhesive or by sewing. Pairs of self-adhesive labels can be provided on a peel-off backing sheet. <IMAGE>
