Title: Variable-displacement pump
IPC: F04B1/08
Filed: 1982-03-02
Abstract: A variable-displacement pump (1) for hydraulic fluids including a zero- delivery regulating device (4) contains a biased control spring (5) whose bias is adjustable automatically to two values with the aid of a special control device, by electric or hydraulic means. The higher preloading value is set when a user (2) of the pump pressure generated by the hydraulic pump (1) is connected by a corresponding switching action of a user change- over valve (14). The lower preloading value is set when the user is disconnected. This permits the reduction of the maximum working pressure of the minimum fluid delivery in the case of a hydraulic pump (1) with zero-delivery regulating device under zero-delivery regulating conditions, so that there results saving of energy and decline in noises, with the user disconnected. <IMAGE>

Title: FSK receiver with twin stable state PLL
Inventor: BEESLEY GRAHAM EDGAR
IPC: H04L27/16
Filed: 1982-05-26
Abstract: A heterodyne radio receiver is provided that is particularly suited to demodulating a binary FSK signal. A voltage controlled oscillator (VCO 20) generates a reference signal at the nominal center frequency of the input signal, and the signals are mixed in mixer (8) to produce an intermediate frequency (I.F.) signal. The I.F. is limited (14) and then compared with the output of a reference oscillator (22) using a phase detector (16) with a triangular transfer characteristic, the output of which is fed back to the VCO via a loop filter (18). Three ways of deriving a demodulated output are disclosed: using an analogue recovery circuit (44); or digitally using an auxiliary phase detector (30) responsive to the reference signal phase shifted 90 degrees and to the limited I.F.; or digitally using a D-type latch (54), Fig. 5 (not shown) receiving the limited I.F. and clocked by the reference signal. <IMAGE>

Title: Wheeled container
Inventor: NELZI GIAMPAOLA
IPC: B62B3/00
Filed: 1982-06-24
Abstract: A container has a wheeled base (1) detachably connected by clips (9) to side walls (8) to whose corresponding rear upright edges are connected the respective upright edges of a rear wall (12). Said edges of the wall (12) carry right-angled brackets (13, 13%) of which the brackets (13) are of reversed positioning to that of the bracket (13%), at each side. The clips (9) are such as to assume, automatically under the influence of gravity, positions in which they prevent unintended detachment of the side walls (8) from the base (1). The brackets (13, 13%) may be replaced by members (30, 31) made of wire or rod material. The arrangement allows the wall (12) to be removed by sliding upwards until the brackets (13%) clear the tops of the side walls (8) and then disengaging the brackets (13). <IMAGE>

Title: Silicone polyimide copolymers, condensation vulcanizable compositions obtained therefrom, and methods for making
Inventor: RYANG HONG-SON
IPC: C08G77/455
Filed: 1983-11-17
Abstract: Silicone-polyimide copolymers having terminal silanol or silicon hydride radicals are based on the use of a norbornene terminated polyimide, containing polyimide blocks of the formula   <IMAGE> wherein R is a divalent organic radical, R<1> to R<6> are monovalent organic radicals, Y is O or C(R<1>)2 and n is 0- 200. A hydrosilation reaction is employed to introduce silicon- hydrogen into the terminal position of the polyimide having norbornene termination. The resulting hydrosilyl terminated polyimide is reacted with silanol terminated polydiorganosiloxane in the presence of a catalyst to produce silanol terminated polydiorganosiloxane- polyimide copolymer. Boom temperature or low temperature condensation vulcanizable compositions based on the use of such silanol-terminated copolymers provide cured silicone- polyimide copolymers exhibiting improved toughness.
