Patent GB-2066397-A (GB)
Title: Hydraulic two-circuit brake systems
IPC: B60T13/14
Filed: 1980-12-19
Abstract: An hydraulic two-circuit external force brake is proposed in which a brake valve (7) has two separate plunger-actuated valves (8, 9), one for each brake circuit and the two plungers (17, 18) are interconnected by way of a compensating lever or balance beam (14) and are in the form of outlet slide valves and have equal effective pressure surfaces each subjected in use to the pressure introduced by the respective separate valve. One plunger (17) has an associated piston (54) which is subjected to the pressure introduced by the respective plunger-actuated separate valve (8) and which acts upon the compensating lever (14) to upset the equilibrium whereby, upon application of the brakes, a higher pressure is introduced into the brake circuit (II) with which the non-assisted plunger (18) is associated than in the brake circuit (I) having the plunger (17) assisted by the piston (54). The brake circuit having the reduced pressure is the front axle brake circuit I, and the pressure lag in the front axle brake circuit is made up at full brake pressure. <IMAGE>

Title: Variable frequency oscillator
IPC: H03L7/02
Filed: 1981-02-25
Abstract: A variable frequency oscillator comprises a voltage-controlled oscillator 4 which has a feedback loop including a delay line 16 and a phase detector 24 which is responsive to the phases of the signals at the input and the output of the delay line for providing a control voltage 26 for the VCO. The feedback loop includes a phase shifter 18 for varying the frequency of the VCO. The VCO includes range shifting means e.g. a manually-adjustable reactance, for adjusting its free- running frequency in order to shift the range within which the control voltage controls the VCO frequency. Preferably, the phase shifter can be continuously, successively rotated to permit a continuous scanning throughout the overall tuning range, if the range adjusting means is periodically operated when the control voltage (displayed at 39) reaches an upper or lower limit to bring control voltage back to the opposite limit. Preferably, the phase shifter 18 comprises a pair of inductances (42,44), Figs 2,3 (not shown) receiving differently-phased signals 32, 34 from the voltage controlled oscillator and spaced around an axis about which a third inductance (46) can rotate relative to the first two inductances. <IMAGE>

Title: Cooking apparatus
IPC: H05B3/74
Filed: 1981-03-04
Abstract: An electric cooker or cooking hob has a ceramic plate 2 on which there are a number of hot plate areas each heated by a respective annular heating element 4 disposed within an insulating housing 7. A temperature dependent resistor 9 is disposed below the hot plate area at the centre of focus of a reflector 8 which is arranged to focus radiant energy from the hot plate area on to the resistor 9 while at the same time shielding the resistor 9 from direct radiation from the electric heating element 4. The signal derived from the resistor 9 is a measure of the temperature of the hot plate and can be used to provide a thermal tripping function to prevent over-heating of the hot plate area and/or to carry out closed loop control of the temperature of the hot plate area. The reflector 8 may be replaced by a shield which shields the resistor 9 from direct heating by the heating element 4. A further annular heating element surrounding the element 4 may be provided, with the control circuitry enabling either the element 4 alone or element 4 plus the outer element. <IMAGE>

Title: Price-computing device including a printer
IPC: G07G5/00
Filed: 1981-03-19
Abstract: A device comprises an evaluating unit having a tabulator and printer 20 for issuing a cash slip 19 bearing details of a sales transaction at least some of which are computed by unit from data set by tabulator and optionally a weighing pan. Cash slip 19 has unvarying information e.g. name of the firm variable information e.g. details of the transaction. Printer 20 incorporates a single dot matrix printing mechanism 21 which prints both sets of information. Mechanism 21 may be controlled to print the unvarying information when the preceding sales slip is removed. This function is sensed by feeler member 55 which actuates switch 54 to recall the fixed heading data from PROM 47. The variable information is printed without reliance upon PROM 47. PROM 47 is contained in an insert 46 which is interchangeably located in a pocket 45 whereby the nature of the unvarying information can be changed by replacing insert 46. A method of programming the PROM starting by recording original artwork with a video camera is disclosed (and shown in Fig. 7). <IMAGE>

Title: Tape drive methods and apparatus with tape slackening feature
Inventor: SERAFINI JOSEPH JAMES
IPC: G11B15/18
Filed: 1982-12-15
Abstract: Methods and apparatus for driving a tape (15) relative to a slant track recording scanner (12) or other surface employ a capstan (38) rotating in a first sense of rotation for an advancement of the tape (15). The advancing tape is tensioned into engagement with the surface. The capstan is selectively decelerated to stop the tensioned tape. In practice, this could bind the tape to the particular surface, rendering subsequent tape advancement difficult. The disclosed invention slackens the tensioned tape (15) from the surface (12) by rotating the capstan (38) in a second sense of rotation opposite to the mentioned first sense of rotation upon deceleration of the capstan. The back EMF of the decelerating motor (23) may be utilized for this purpose. The capstan is stopped upon slackening of the tape from the surface. <IMAGE>
