Title: Digital phase-locked loop
Inventor: JOHNSON KENNETH CHARLES
IPC: H03L7/00
Filed: 1983-04-07
Abstract: A phase locked loop system for receiving a data input DIN with a predetermined bit frequency f includes a source (10, D1 D2) of clock signals with a frequency nominally equal to f, means (14-16) for dividing each clock period into three regions corresponding to early, normal and late arrival of the data signal relative to the clock signal and means (D3 D4 D5) for deciding which region the data signal occurs in and for respectively advancing or retarding the phase of the clock signal if the data signal occurs in the early or late region. A frequency 4f provided by crystal oscillator 10 is fed to D-type bistables D1, D2 forming a divide-by-four counter, which can be advanced or retarded by 90 DEG  by placing or holding D2 in its inset state. Bistable D6 provides a data output RxD in synchronism with the re-timed clock signal RxC. <IMAGE>

Title: Resilient rubber mounting in particular engine mounting for motor vehicles and the like
Inventor: WOESLER ENRENFRIED
IPC: F16F3/093
Filed: 1983-06-07
Abstract: A resilient rubber mounting, in particular an engine mounting for motor vehicles, is provided with rigid inner and outer parts to be fixed respectively to the engine casing and the vehicle frame. The rigid parts (1, 2, 3 and 4) are separated by intermediate assemblies made of rubber material of differing shock absorption properties. One assembly (9) has limited shock-absorption properties for the take up of the main load and for the damping of high frequency vibrations of small amplitude, and at least one other assembly is provided with greater shock-absorption properties for the damping of lower frequency vibrations with greater amplitude. The rigid inner part is made up of three parts, an axially inner sleeve (1) and two axially outer sleeve parts (2 and 3). The rigid outer part (4) is in a double cone-shape. The rubber assembly (9) gripping the axially inner sleeve (1) has limited shock absorption properties and is joined by vulcanisation to a cylindrical section (6) of the outer part (4), whilst the rubber assembly (10) vulcanised to the axially outer sleeve parts (2 and 3) and which has greater shock absorption properties cooperates with the outer part (4) in an adjacent and supporting manner resulting from axial bracing against the cone-shaped end parts (7 and 8) of the rigid outer part (4). <IMAGE>

Title: Containers for beverages
Inventor: GOTCH HENRY
IPC: B67D1/08
Filed: 1983-06-30
Abstract: A beverage cask or container 1 has a bung hole outlet housing 2 within which is located a body 4 carrying a liquid extractor tube 9 and a valve means 17,18,19 which cooperates with a top fitting (not shown) to open passageways for introduction of gas A and extraction of liquid B. The body 4 and valve means is retained by a top plate 15 of which the marginal edge portions 16 have been deformed to form a "clench" around the flared top 3 of the housing 2. The clenched top plate forms the sole means of retaining the valve and body assembly in position. The dimensions of the clenched plate 15 are such that the top fitting (not shown) may be directly coupled therewith and the plate further forms an integral constructional part of the valve means being a seating surface for seal 17. The arragement provides security as it is necessary to cut-away the plate 15 to gain access to the container but nevertheless the plate can be fitted and removed easily using appropriate equipment. The need for providing threading on the outlet 2 to secure body 5 is avoided.

Title: Wood screws
Inventor: GILL PETER JOHN
IPC: F16B25/10
Filed: 1983-09-28
Abstract: A wood screw particularly suitable for application by automatic screw driving apparatus to woods which are normally prone to splitting has a counter-sunk head 10, a screw-threaded shank 12 and a chisel shaped point 14. The threads of the shank 12 extend over the full length of the screw along the edges 16 of the chisel point 14 but the threads may terminate at the commencement of the chisel point 14. The provision of the chisel point 14 enables the screw to be driven into woods which are prone to splitting without the provision of a pilot hole in the wood and without splitting the wood. <IMAGE>

Patent GB-2144483-A (GB)
Title: Locking Devices
Inventor: MILLER IAN ANDERSON
IPC: G07C9/00
Filed: 1984-07-30
Abstract: A keyhole-less electronic padlock uses inductive coupling from a key to a lock to transmit a multibit lock code from the key to the lock to release the lock. The lock and key are reprogrammable to a different lock code by a programming unit which generates a new lock code by combining the old lock code with a random number. The lock circuitry provides a delay of e.g. one second after unsuccessfully operating with one lock code before it will process another to make it impracticable to attempt to break the lock code by a purely random method. The key circuitry is automatically switched on by a reed switch in the key which is closed by a magnet element on the lock when the two are brought together, to conserve battery power. The mechanical locking structure may include a rod 169 which can move into engagement with the end of the hasp, and two retaining springs locatable symmetrically on opposed sides of the rod in a recess on the rod, to resist opening of the lock by gross mechanical shock. The lock is released by solenoids moving the springs apart. If a two- part lock casing is employed, the two parts may be held together by a bolt which is accessible only through the aperture which receives the free end of the hasp, so that the casing can only be disassembled when the lock is open. <IMAGE>

Title: Data retrieval system
Inventor: GIVERTZ MATANIA JOCHANAN
IPC: H04N5/445
Filed: 1984-10-26
Abstract: A data retrieval system, intended principally for allowing a computer to make use of the viewdata or teletext information services, stores selected portions of data corresponding, for example, to one of the pages of transmitted information and feeds the data one byte at a time to the computer in the order in which alphanumeric characters represented by the bytes appear on the page. To do this, data selected in real time by a teletext or viewdata decoder (12) is written to a random access memory (16) during a predetermined time interval sufficient to accumulate a page of information in the memory, and stored in the memory (16) in an interlaced line format. After the time interval, a microprocessor (18), with the aid of a look-up table, reads out the lines of data from the memory one byte at a time in the order that the lines appear in the page, and converts these bytes to a serial ASCII coded data stream suitable for storage, processing or display in a number of different types of host computer. The system also allows commands, such as page numbers, to be converted to a form suitable for controlling the selection of data in the decoder (12).

Patent GB-2157838-A (GB)
Title: Electrostatic voltmeter
Inventor: SNELLING CHRISTOPHER
IPC: G01R5/28
Filed: 1985-04-12
Abstract: An electrostatic voltmeter (10), which can be used in the image reading device of a multi-mode copier/printer (Figs, 5, 6) comprises a microdeflector probe (13) for measuring the charge on a surface (35), e.g. the photoconductive surface in xerography. The probe comprises a flexible finger (14) cantilevered on a base (16) which is electrically biased to a predetermined potential Vre via connection (17). A sensing electrode (27) on the finger has a portion (33) which can be positioned in spaced relation adjacent surface (35), the capacitive relation thus established creating on the sensing electrode a charge representative of the charge on the surface (35). The potential difference between the finger and the base causes the finger to deflect. This deflection can be converted to a signal representing the charge on the surface (35) e.g. by directing a beam (41) of light and detecting the reflected beam with a detector (45) which can be arranged to receive the reflected light only when the finger undergoes deflection of predetermined amplitude. <IMAGE>
