Title: Steel cables of composite twist for reinforcing rubber - which increase the stiffness weight ratio of tyre reinforcement
IPC: D07B1/10
Filed: 1975-05-12
Abstract: Steel cables for rubber reinforcement, comprising one gp. of plain filaments in parallel contact and twisted into a permanently helical cable and overwound by one or more ancillary filaments laid as a helix of similar rotation and pitch but out of phase longitudinally. The core filaments are not twisted with respect to each other. Esp. suitable for reinforcing sub tread breakers or other reinforced parts of tyre carcasses. Longitudinal stresses are shared fairly equally between the individual filaments of both the core gp. and the externally wound gps. thus enhancing the stiffness and strength by comparison with cables having interlaced cores and/or small external filaments. The matrix rubber can readily penetrate between the core cables, improving interfacial bonding and eliminating interstitial cable crevices which are prone to local delamination or corrosion.

Title: Picture enhancement circuit with three pick=ups - ensures that sharp edges are formed to black and white transitions by detecting grey level
IPC: H04N1/409
Filed: 1981-08-26
Abstract: An enhanced copy of an original picture (4) is produced by optical scanning. The overall grey level of the original is monitored by a third detector (3). Light from a source (8) is reflected from the original through a lens assembly (5), and onto a 45 degree semi-reflecting mirror (9). A sharply defined signal is provided by a transducer (1), via a small diameter diaphragm (6). The other detector (2) produces a less well-defined signal, via a larger diameter diaphragm (7). The focussed and unfocussed signals are summed by a differential amplifier (10), the output of which is fed to a multiplier (12). The multiplication factor is dependant on the gray level detected (3) before scanning commences. The multiplier output and the focussed output signal are fed to a counter, to produce the enhanced picture signal.

Title: Clocked comparator using four pairs of transistors - has clocked switching transistors connected between collectors of input transistors
IPC: G01R19/00
Filed: 1983-10-10
Abstract: Clocked comparator circuits with output limitation are used in parallel a-d connectors. The present circuit uses four pairs of transistors, in place of the usual three, to overcome the problem of clock frequency interference which can appear on the analogue and reference inputs in conventional circuits. The clocked switching transistors (T7,T8) are connected between the collectors of the input transistors (T1,T2) and the output loads (8,9) rather than between the emitters and the common current source (13). An inverted clock signal is fed to another pair of transistors (T9,T10) which connect the commoned emitters of the cross-connected limiting pair (T3,T4) to the collectors of the input pair (T1,T2).

Patent NL-8600217-A (NL)
IPC: G06F11/36
Filed: 1986-01-30
Abstract: A data processing arrangement which comprises a memory device provided with a memory with a first field in which memory words are stored or can be stored and a second field in which an error protection bit can be stored for every memory word from the first field. The memory device further comprises an error protection bit generator for the generation of error protection bits and a coincidence circuit. This coincidence circuit operates in two different modes, on the one hand, an error protection mode in which error protection operations, suh as for example the use of parity bits, take place in the known manner and, on the other hand, a coincidence mode in which the error protection operations are suppressed and replaced by coincidence operations. These coincidence operations make it possible to find out whether access operations are being performed at pre-determined memory addresses. In order to make these coincidnece operations possible, a coincidence bit is stored in the second field at these pre-determined memory addresses before the coincidence circuit is allowed to operate in the coincidence mode.

Title: Pump and system employed therein
Inventor: GUTHRIE ROGER THACKSTON
IPC: F04B7/06
Filed: 1984-11-13
Abstract: A system for delivering controlled quantities of a stream of fluid to an application zone includes a positive displacement pump (100) comprising a piston housing (111) with an interior cylindrical wall (115). A pumping chamber (116) lies adjacent a closed end of the pump cylinder. A reciprocating and rotating piston (118) in the cylinder draws fluid into the chamber (116) and expels the fluid therefrom. A barrier fluid inlet (122) adjacent the piston (118) enables barrier fluid to be delivered to the cylinder at a pressure greater than the maximum fluid pressure in the pumping chamber (116) to preclude migration of pumping fluid along the piston to the opposite end of the cylinder.

Title: Process for recovering purified growth hormones from genetically engineered microorganisms
IPC: C12P21/00
Filed: 1985-08-23
Abstract: This invention concerns a method for recovering a purified eucaryotic growth hormone or an analog thereof from a bacterial cell in which the growth hormone or analog has been produced by means of expression of a DNA sequence encoding the hormone or analog. The method involves the following steps: (a) disrupting the cell wall of the bacterial cell or fragments thereof to produce a lysate; (b) separating a precipitate containing particulate and insoluble material from the lysate; (c) preparing suspension of the separated precipitate in an appropriate buffer solution; (d) treating the suspension to effect contact between liquid and solids; (e) separating partially or completely precipitated material from the liquid-solids contacted suspension; (f) solubilizing the separated precipitate in a sufficient amount of water and adjusting the pH to a suitable alkaline pH to form a solution; (g) separating the solubilized hormone or analog from other cellular components by ultrafiltration under suitable conditions to produce an ultrafiltrate containing the hormone or analog and a retentate, and (h) treating the solubilized hormone or analog so as to concentrate the hormone or analog and thereby recover purified hormone or analog. Separations may be effected by ultrafiltration or centrifugation. Sonication as well as the ultrafiltration in step (i) may be repeated. Additionally, most of the process steps may be performed in a continuous flow and may be automated. Suitable hormone-producing bacterial cells for use in this invention include genetically modified strains of Escherichia coli. Growth hormones which can be recovered and purified using this invention include bovine, porcine, chicken, and human growth hormones, and analogs thereof.
