Title: Brake control for aircraft wheel - with electronic servo control and correction circuit for improved sensitivity
IPC: B60T8/58
Filed: 1973-09-10
Abstract: Wheel speed monitors generate wheel speed signals which are compared with reference speed signals. They are differentiated and compared with programmed braking signals. The system is given improved sensitivity by amplifying the control signal derived by the system by a factor k/vm where v is the vehicle speed and the factor m is determined by the vehicle braking properties. The arrangement may alternatively be used to control the steering surfaces of air or watercraft, and is electronically activated. The comparator produces a digital signal to operate the wheel brake to a maximum value without slipping.

Title: Dough piece divider and former for mechanised bakery - divides each piece into 2,3 or 4 fractions to form small loaves
IPC: A21C3/02
Filed: 1975-06-05
Abstract: Dough forming and dividing plant for mechanised bakeries comprises adjustable guides to lead an original dough piece into a first forming and elongating operating which produces an elongated dough roll or stick. An optional cutter shaft with 1, 2 or 3 discs can be brought into use to divide the stick into 2, 3 or 4 fractions. these fractions are taken forward on a slow conveyor to allow dough to recover after first forming and dividing. The recovery conveyor delivers the fractions, one into each of a series of laterally divergent guide channels. Fractions delivered from the channels to a second forming operation can be elongated towards each other without contacting. Dough pieces formed at a rate of 700-1500 per hour can be divided into fractions, e.g. for loaves of about 50 grammes, which are thus produced at 3000 to 6000 per hour. A single process plane of fixed vol. capacity, e.g. 100 kg of flour in 20 mins., can be quickly adapted from single file prodn. to produce 2, 3 or 4 times as many loaves of proportionately smaller vol.
