Patent GB-2072943-A (GB)
Title: Piezo-electric crystal vibrator
IPC: H03H9/215
Filed: 1981-03-02
Abstract: A mode coupled tuning fork type quartz crystal vibrator utilizing two different vibrational modes is provided. The vibrator includes at least one electrode on each tuning fork arm for adjusting the resonant frequency of the main vibration and an electrode for adjusting the frequency-temperature characteristic of the vibrator. The main vibration is in the flexural mode (F1) and the sub-vibration is in the torsional mode (T0). The resonant frequency of the first overtone in the flextural mode is designated by fF and the resonant frequency of the fundamental vibration in the torsional mode is denoted by fT. The difference between fF and fT defined as  DELTA f=fF-fT determines the frequency-temperature characteristics of the mode coupled vibrator. The electrodes for adjusting fF are substantially triangular in shape and the electrodes for adjusting fT are substantially rectangular in shape. These electrodes are disposed at positions near the top of each tuning fork arm and on both principal surfaces of the vibrators. The resonant frequencies are adjusted by removing a portion of electrode material or adding a strip of metal to the electrode. Preselected oscillation frequency and frequency-temperature characteristics in the form of a cubic curve at ambient temperatures are obtained by first adjusting  DELTA f to a preselected value  DELTA fO and then adjusting fF to a preselected value fF0 at the same time maintaining  DELTA f at the value  DELTA f0.

Title: Releasable securing device
IPC: F16B21/08
Filed: 1981-03-10
Abstract: A device for securing parts together comprises a pin (10) with axially spaced stops (11 and 13). One of the stops (11) constitutes a latch and is made from a length of resilient wire. At one end the wire is shaped either as a coil (17) and mounted on the adjacent end portion (15) of the pin, or as a mounting pin (20), which enters an axial hole in the pin. The other end (19) of the wire projects into a transverse hole (16) in the pin. The intermediate part (18) of the wire is normally inclined to the axis of the pin. When the pin is pushed latch-first into aligned holes in the parts to be secured together, the intermediate part of the latch is automatically urged towards the pin. When the latch emerges from the holes it springs back to its normal position, and the transverse end (19) prevents withdrawal of the pin. The fixed stop (13) may be replaced by a second latch. <IMAGE>

Title: A trailer coupling device for vehicles
IPC: B60D1/52
Filed: 1981-08-24
Abstract: The trailer coupling has a support tube 1 adapted to be secured to a vehicle and which receives a cylindrical part 4 of a neck 2, the neck 2 having a coupling ball 3 on its outermost end. The neck is secured to the support tube 1 by a fastening bolt 7 passing transversely through the neck 2. The tube 1 has a transverse slot 18 for receiving the bolt 7, the slot leading to a bore 11 which serves to receive a collar 13 on the bolt of larger diameter than the remainder of the bolt 7 so that when the bolt 7 is tightened the collar 13 enters the bore 11 to thereby prevent the bolt 7 and hence the neck 2 from being detached from the tube 1. A spring clip 16 engageable with a part 17 secured to the tube 1 and a groove 15 in the collar 13 prevents accidental release of the bolt 7 from the tube 2. A locking pin serves to ensure captive mounting of the bolt in the neck 2. <IMAGE>
Patent GB-2087175-A (GB)
Title: Flasher apparatus for motor vehicles
IPC: B60Q1/38
Filed: 1981-10-14
Abstract: In order to protect the output switch (T1) of the apparatus, means are provided to render the switch inoperative as a result of an excess current flow. T1 is normally on and is switched by the action of T2 and oscillator A1. When SW1 is closed a voltage builds on the selected lamp (L1 or L2). If this does not exceed the reference set by R6 and R7 at the negative input of A2 within a time set by R8 and C2 then the output of A2 is low, disabling T1. Thus a short circuit or a low load is detected. An overload is detected by means of sensing resistor R5. Should the current exceed the required value the output of A3 goes lower than the reference set by R16 and R17 causing monostable A5, A6 to go high for a period set by R21 and C3. This makes the output of A1 low, disabling T1. <IMAGE>

Title: Vehicle park counting equipment
Inventor: JONES KEVIN GEORGE
IPC: G07C9/00
Filed: 1982-01-25
Abstract: Vehicles are counted into and out of the park. Cumulative Errors may occur when vehicles enter by an exit lane or leave by an entry lane or when manoeuvring in either. This equipment provides automatic correction when the vehicle park is substantially full or empty. Upper Threshold (UT) and Absolute Maximum Count (AMC) values are preset. If the count is too high the UT level will be exceeded, but vehicles entering the vehicle park will still find spaces. In this case the count will carry on increasing until it reaches the AMC at which the counter is stopped. If vehicle continue to enter the park, an error counter is incremented until at a predetermined level, an alarm is set. As vehicles leave the park, the error counter and main counter are decremented together, away from the AMC, which in effect causes the equipment to disregard the excess count. A similar arrangement corrects a too low count when the counter attempts to decrement below zero. <IMAGE>

Title: Interface circuit
IPC: H03F3/45
Filed: 1982-03-05
Abstract: An interface circuit for connecting a telephone exchange line to a subscriber's line interface circuit is described which permits the transmission of signals differentially appearing on the exchange line to be transmitted to the interface circuit but which is arranged to float with common mode voltages appearing on the exchange line. The circuit proposed uses two parallel current circuits carrying equal, controlled currents with series transistors to which the input voltage from the exchange line is differentially applied so that the differential voltage appears across a resistor joining corresponding points on the parallel circuits and an output current is derived from the parallel circuits in dependence on the current through the resistors. <IMAGE>

Title: Facsimile system
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/333
Filed: 1983-02-14
Abstract: In a facsimile system of the invention, prior to image transmission, check signals of predetermined image patterns are transmitted from a facsimile transmitter and received by a facsimile receiver so as to check if a predetermined image transmitted by the transmitter may be correctly received by the receiver. If an error is caused, the content of the error is detected so as to allow selection of the image transmission method or line disconnection. Image quality can be significantly improved even if automatic equalization function is not included. By using a plurality of types of check signals corresponding to possible errors, such as a skip check signal and a black ghost check signal, the content of an error can be identified to allow discrimination of a suitable image transmission method or selection of line disconnection. <IMAGE>
