Patent GB-2061750-A (GB)
Title: Screening apparatus for drilling mud
IPC: B01D33/03
Filed: 1980-10-27
Abstract: Screening of drilling mud is carried out using a screen comprising e.g. two hollow open-ended coaxial frusto-conical screening members (6 and 10), one inside the other and tapering in the same direction. The individual screening members have different mesh sizes which reduce from the inner to the outer screening members. The inner screening member is extended at its narrower end by an imperforate similarly tapering hollow open- ended neck (11) The screen comprises a horizontal central shaft (1) which is rotated and possibly also vibrated of the wider end of the screen. Contaminated mud (13) is fed into the neck (11) and solid particulate contaminants (14 and 15) pass through and along the screening members depending upon their sizes and are dumped from the wider end of the screen. Purified mud (16) passes through the outer screening member (10) into a collecting tank for further use at the drill bit. <IMAGE>

Title: Glass breakage detector safety mounting
IPC: G08B13/04
Filed: 1981-01-13
Abstract: A housing 1, 2 containing a security device and circuitry therefor is mounted to a window pane 3 via two bondings in series. The housing is attached to an element 6 exerting a magnetic field on the circuitry by a weak bonding 19, while the element is attached to the window pane by a strong bonding 18. There may be other bondings 17 directly between the housing 1, 2 and the window pane 3. An intruder forcing the security device and its housing from the window pane will automatically break the weak bonding 19 and therefore increase the distance between the element 6 and the housing, causing the magnetic field to alter. The circuitry may contain a magnetically operated reed switch 16 which will then initiate an alarm. <IMAGE>

Title: Cable operating gimbal automotive transmission shifter and gear lockout
IPC: F16H63/20
Filed: 1981-01-13
Abstract: A gimbal-type automotive transmission shifter and gear lockout is provided comprising a gear selecting shift lever; a pivotable shift lever carrier; and a stationary base for mounting the transmission shifter in an automotive vehicle. The shift lever and shift lever carrier are pivotable about first and second generally orthogonal axes, respectively. The shift lever is pivotable relative to the carrier about the first axis and the carrier is pivotable relative to the base about a second axis. Appropriate linkage is provided for translating these pivotable movements to the transmission for selecting a desired transmission drive ratio. A gear lockout is provided by a first gate disposed on the base. A detent is mounted for reciprocal movement with respect to the base. Biasing means is provided for biasing the detent into engagement with the base. The biasing means thereby prevents entry of the detent into the first gate and thus provides a positive first lockout for at least one gear position. Means for manually actuating the detent comprising a pushbutton or pull ring-type lockout actuator is provided for overcoming the biasing means and aligning the detent with the first gate to provide for entry into the locked out gear.

Title: Method and apparatus for heating
IPC: A01G9/26
Filed: 1981-09-30
Abstract: Material (12), especially liquid or solid, is heated by embedding or immersing in the material a bare electrical conductor (10). A current is then driven through the conductor from the secondary (18) of an A.C. transformer (16) having its primary (19) and secondary (18) windings spooled separately and spaced apart so that the phase relationship between the primary and secondary currents is disturbed. The conductor is used without insulation so as to maximise heat transfer to the material and also to obtain direct ohmic heating of the material by way of leakage currents. Liquid may also be heated by passing it through a conductive pipe. <IMAGE>

Patent GB-2120418-A (GB)
Title: Hydraulic pump control
Inventor: YOUNG ALASTAIR JOHN
IPC: F15B11/17
Filed: 1982-04-15
Abstract: A fluid pressure supply system incorporates two pumping units P1 and P2 for supplying fluid under pressure to a load 13. Pump P1 supplies the load continuously. Pump P2 is also connected to the load 13 through a load valve 15 when pressure in the load is low but is connected to drain through the load valve when load pressure is high. A pressure relief valve 14 controls the load valve 15 by a connection from port 22 to port 28 which applies system pressure to the load valve at low pressure and drain pressure via port 23 at higher pressures in response to relief valve spool movement. The high control pressure moves load valve spool 25 to connect its inlet port 29 to load 13 through port 33. When system pressure is high and control pressure is low, inlet 29 is connected to drain port 31 so that pump P2 is off-load in that it is pumping direct to drain. In another embodiment, (Fig. 3, not shown) a combined valve 51 provides both functions of valves 15 and 14. <IMAGE>

Title: An FM radio receiver incorporating a muting circuit
Inventor: IENAKA MASANORI
IPC: H03G11/08
Filed: 1982-10-13
Abstract: In an FM radio receiver (Figs. 8 and 10) incorporating a muting circuit 10, the output signal of a detuning detector circuit (4) is applied to the input terminals of first and second mute control circuits (11, 12) which control the muting operations of a pre- amplifier (7) for amplifying a stereo composite signal and the muting circuit (10) connected to the output of a stereo demodulation circuit respectively. Discrimination levels these first and second mute control circuits are set to mutually different levels so that when the receiver becomes in a detuned state the signal transmission of the muting circuit is inhibited and thereafter the signal transmission of the pre-amplifier (7) is inhibited. This eliminates popping noise at the time of changes from tuning to detuning and vice versa. In examples of the muting circuit (Figs. 5 and 7) signal transmission is effected when a first constant current source (Q5), connected to the emitters of (Q1, Q2) is operative and a second constant current source (Q6) connected to the emitters of (Q3, Q4) is operative. No signal transmission is effected in the opposite case. To eliminate the popping noise when the power source is switched on, a switching element (Q7) is connected in parallel to a bias resistor (RB) and is kept in the ON state for a predetermined period of time after switching on the power source. <IMAGE>

Title: Bonding semiconductive bodies
Inventor: JANSSEN ADRIAN PERRIN
IPC: H01L21/60
Filed: 1983-03-15
Abstract: Reproduceability and reliability problems associated with using a solder perform to bond a semiconductor laser chip (1) to a heat sink (2) are avoided by a diffusion associated bonding method. Both surfaces to be bonded are coated with relatively thick layers of gold (3, 7), one or both of which is/are then coated with a submicron thickness tin layer (5) whose surface is, if required, protected from oxidation with a further coating (6) of gold. The two components are assembled and heated to bond them together by causing a molten gold-tin eutectic layer to be formed which then diffuses into the gold layers without penetrating right through them. <IMAGE>

Title: Distribution of clock pulses
Inventor: ABRAHAM GRAHAM PHILIP
IPC: G06F1/10
Filed: 1983-09-05
Abstract: In a digital computer system, the clock pulses arriving at each individual module 10 are sampled at 19 and compared at 20 with the clock pulses obtained directly from the clock circuit 14. The transit times of the clock pulses are adjusted (by programmable delay 18) until the two sets of pulses coincide, indicating that the delay between the two sets of pulses is equal to an integral number (usually one) of clock periods. Thus, the period of the clock is used as a reference value for setting up the transit times of the pulses. The clock frequency may be first adjusted from its normal operational value so as to set the period at the desired value. <IMAGE>
