Title: Improvements in or relating to Parking Brake Arrangements for Hydraulic Brake Systems
IPC: F16D55/22
Filed: 1966-11-30
Abstract: 1,152,658. Hydraulic brakes. ALFRED TEVES G.m.b.H. 30 Nov., 1966 [7 May, 1966], No. 53661/66. Headings F2E and F2F. In a dual circuit hydraulic brake system for a road vehicle employing a tandem master cylinder 11, the wheel brake cylinders are provided with mechanical locking means each comprising a locking device which can be moved in the cylinder by an operating lever carried by the cylinder and connected, e.g., to a hand-operated cable linkage 20 to follow up the brake-applying movement of the piston, so that if one circuit fails, the brake can be locked via the other circuit. Preferably, a self-wedging arrangement is provided between the device and the piston or between the piston and an output member to lock the piston in applied position until the device is withdrawn. In the embodiment of Fig. 3, the device comprises a member 39 having a tapered outer surface in order to provide a self-wedging action, by means of balls 41 mounted in a cage 43, between it and a recess in piston 32, which operates in a bore in housing 31 to apply an associated pad 35 to a disc 30. The member 39 is carried on a pin 38 adjustably secured to the housing and is advanced, in opposition to the action of a spring 44, by a nut 46 threadedly engaging the pin and which is rotated through helical gearing 47, 48 by a lever 49, a roller thrust bearing 45 being interposed between the nut and the member 39. The brake shown comprises a pair of pistons in a common housing for applying pads to the opposite faces of the disc, each piston having an associated follow-up device and the two levers 49 being connected as shown in Fig. 1 to the linkage 20, there being two cables 19, 19<SP>1</SP>, respectively associated with each of the two rear wheel disc brake assembly 15, 15<SP>1</SP> of the vehicle. The follow-up device may be used as an emergency brake in the event of hydraulic failure in both hydraulic circuits. The brake system may be of the kind having disc brakes on the front wheels only and drum brakes at the rear (Fig. 2, not shown). Three alternative constructions of wheel brake cylinder (Figs. 4, 5 and 6, not shown) are disclosed, Fig. 4 disclosing an alternative disc brake construction in which the lever (56) is pivoted coaxially with the cylinder and, via a threaded sleeve (55) and ball race (57) acts directly on the follow-up member (52), while the other two constructions are drum brake cylinders, Fig. 5, disclosing a cylinder in which a threaded pin (61) coaxial with the piston (64) has a lever directly secured to it, the pin acting in conjunction with an automatic friction adjuster system (65, 67) between the piston and output rod (66), and Fig. 6 being similar, but including helical gearing and a lever arrangement as in Fig. 3.

Abstract: 1,208,582. Pulse radar. WESTINGHOUSE ELECTRIC CORP. 4 Dec., 1967 [6 Jan., 1967], No. 54963/67. Heading H4D. In a pulse radar system, the carrier wave is phase-shifted by 180 degrees for part of the pulse duration: the phase-shift is produced by changing the frequency of a magnetron by loading its output. At the receiver pulse compression is effected. In an embodiment a coupler 18 transfers the magnetron output to a duplexer 24: a portion of the magnetron output is fed via a coupler 22 and a gate 25 to a phase-shifter 20, gate 25 being opened for a short within-pulse interval T (see Figs. 2A, 2B, 2C, none shown) by the output of delay generator 26, the radiated pulse being of duration 5T. The received echo signals are summed as shown to give pulse compression, the delays on lines 36, 38, 40 and 42 being T, 2T, 3T and 4T respectively. For loading the magnetron at the desired instant (e.g. 2À5 T after the beginning of a pulse) a partition may be placed along a waveguide connected to the magnetron, Fig. 4 (not shown); or an opening or duct in the waveguide may be utilized.
