Title: Improvements in or relating to oscillators
Inventor: MYERS ROLAND
IPC: H03L7/181
Filed: 1982-06-15
Abstract: A variable frequency oscillator 10 has an output frequency Fo responsive to a voltage input Vo derived from an analogue integrator 11 controlled by potentiometer 15, 16, the frequency Fo being displayed on frequency meter 19 having a ghost least important digit. A converter 24 responds to the digit to provide a digital output fed to a digital to analogue converter 20 providing an error voltage Ve whose magnitude is proportional to the deviation of the digit from a datum, e.g. 5, and whose polarity depends whether the deviation is + or -. The voltage Ve is also fed to the integrator 11 to control the voltage Vo. An arrangement is also described in which the voltage Ve is derived from the divider chain of a gate period generator controlling a frequency counter whose input is Fo. The arrangement may give automatic frequency control in a receiver. <IMAGE>

Title: Intruder alarm
Inventor: BRAMALL JOHN
IPC: E05B45/08
Filed: 1987-07-25
Abstract: Micro switches 1 and 2 are connected in series (wiring not shown) and positioned adjustably within recess 17 behind the striker plate 12 of a door jamb. Switch 1 has normally closed contacts which are opened by latch 3 snapping into recess 17 and acting on switch plunger 7 when door 16 shuts, and which remain open until latch 3 is retracted. Switch 2 has normally open contacts and is switched on by locking door 16, when door bolt 14 is ejected against switch plunger 8 to close its contacts and thereby pass electrical potential to switch 1 and prime it. In this mode operating door handle 4 retracts latch 3 thereby allowing the contacts on switch 1 to reclose and make a circuit to initiate a warning device. <IMAGE>
