Title: Smoke detector
IPC: G08B17/11
Filed: 1974-09-25
Abstract: 1510630 Ionization smoke detector circuits TROLEX PRODUCTS Ltd 6 May 1975 [25 Sept 1974] 41792/74 Heading G1N [Also in Division G4] In an ionization smoke detector operable at less than 30V when the smoke is detected a first switch operates and after a delay a second switch which actuates a relay to trigger an alarm. When smoke comes into contact with an ionization smoke detector head 20 adapted for use in a mine, Fig. I (not shown) and connected to terminals 1a, 4a, 5 fed with 18-20 volts from series stabilizer VT3 and Zener ZD7 and the output from D.C. to D.C. invertor isolator 22, the effective impedance thereof across terminals 1a and 5 is lowered so that there is an increase of voltage across resistor R12 and capacitor C3. This switches transistor VT4 ON creating a voltage step across resistor R5 which together with capacitor C2 forms part of a delay circuit 24. After a delay of 2 secs. transistor VT2 switches ON resulting in transistor VT3 being driven OFF so that the stabilized supply is removed from the head 20, isolator 22 and relay RL1. The contacts of the latter close and an alarm (not shown) is actuated. The voltage on the base of VT2 now drops and it eventually switches OFF after a delay of 2 secs determined by capacitor C1. Transistor VT3 now switches ON again and the stabilized supply is applied to the head and isolator. Capacitor C5 now charges and supplies sufficient voltage to transistor VT7 to switch it ON to open the contacts of relay RL1 and switch off the alarm. When C5 is fully charged VT7 switches OFF but the relay remains energized due to the supply from VT3. If smoke is still present the process is repeated. Transistor VT2 may control a light emitting diode LED 1 to provide a visual alarm. A reed switch RS1 may be provided to test the detector device. If the voltage supply drops or fails or the head is removed the alarm is sounded continuously.

Title: Method and apparatus for linear processing of seismic data
IPC: G06E3/00
Filed: 1963-10-30
Abstract: 1,059,448. Processing seismic data. TEXAS INSTRUMENTS Inc. Oct. 30, 1963 [Oct. 30, 1962], No. 42928/63. Heading H4D. Desired components (e.g. primary reflections) and undesired components (e.g. " multiples " or " ghosts ") of a seismic signal have overlapping frequency and wave number spectra, but have different apparent propagation velocities and are separated by a linear, time-invariant, frequency-dependent, multi-channel data processing system which synthesizes a velocity filter. A plurality of seismic signal traces are generated and applied to respective processing channels 1 to N. The traces may be derived from seismometer outputs directly, or from a magnetic tape field record, and may correspond to the outputs of an array of seismometers for a single shot-point or to the output of a single seismometer for a plurality of shot-points. Each channel contains a filter for amplitude-weighting and time-shifting the associated trace as a function of the desired signal frequency for the particular channel, the time shifts and weights for the trace being dependent also upon the undesired signals (made up of coherent noise, due to " multiples " or " ghosts," and random noise) in the other channels. The channel outputs are then summed to provide a signal substantially free of undesired components. The complex frequency response Y n (f) of the nth channel filter is related to the power spectra of the desired and undesired signal components in the nth and other channels by a matrix equation given in a mathematical analysis based on least-mean-square error theory. From data including the number of channels N, the correlation functions for the desired and undesired signals, and the relative delays between desired and undesired signals on adjacent channels, the response Y n (f) may be calculated by digital computer or may be realised by a tapped delay line whose outputs are appropriately weighted and summed. The response of a two-channel embodiment of the processing system, using a tapped delay line filter, is illustrated graphically (Figs. 11 to 21, none shown). In addition to the time-invariant filtering, time-variant processing may first be applied to the seismic traces to correct for normal move-out.

Filed: 1967-09-22
Abstract: 1,192,640. Distance protective arrangements. ENGLISH ELECTRIC CO. Ltd. 20 Sept., 1968 [22 Sept., 1967], No. 43335/67. Heading H2K. In a distance relay arrangement the derivative (di/dt) of a current derived from the current of a protected system is compared with the largest instantaneous value of two rectified voltages as the current passes through zero, one voltage being phase shifted from the other and both being derived from the system voltage, operation being effected when the ratio of the compared quantities exceeds a predetermined value. The arrangement may comprise a current transformer 13 having primary windings energized by a phase current IR and the residual current IO. The output from the transformer is applied to the differentiator circuit 6. This circuit comprises two networks operative on the opposing half cycles to provide a differentiated pulse at each passage of the current through zero. These pulses are applied between a junction 30 in summing network 44, 45, 46 and a junction 29 between bridge rectifiers 31, 32 forming a switching circuit which is gated by differentiated pulses derived from the voltage ER of the protected systems. The rectified voltages are obtained from a voltage transformer secondary winding 49, resistors 50 ... 52 and a rectifier 48, and from a secondary winding 57, a phaseshifting circuit 58 . . . 60 and a rectifier 55. The rectifiers 48, 55 are connected in series across the resistor 46 so that the voltage across the resistor is that which has the largest instantaneous value. A polarity sensitive device 11 responds to the sum of the voltages across the resistors 44... 46 to effect the tripping of a circuitbreaker. A somewhat similar circuit arrangement, Fig. 7 (not shown) may be used as a starting unit and control the opening of a time switch 54 to extend the reach of the relay arrangement.

Title: Thermal-flattening of metallic strip
IPC: C21D7/00
Filed: 1959-12-22
Abstract: 882,756. Straightening; stretching. ARMCO INTERNATIONAL CORPORATION. Dec. 22, 1959 [Dec. 31, 1958], No. 43588/59. Class 83 (4). A process for flattening metal strip comprises continuously moving the strip in a path of travel, and while the strip is so moving, bringing the strip to at least its softening temperature, and while at such temperature alternately deflecting said strip first in one direction and then the other, while at the same time subjecting the strip to tension. Metal strip is fed by rolls 2 over carrier rolls 8 and between staggered rolls 9a, 9b in a heating and soaking section 4 of a furnace 3. The rolls 9a, 9b may be driven or idle. The top rolls 9a are adjustable towards the rolls 9b. The strip then passes through a cooling section 5 of the furnace 3 and is drawn out by rolls 7 driven at a somewhat greater speed than the rolls 6 so that the strip is under tension of, for example, from 1100-2200 and preferably 1500 pounds per square inch, for silicon steel. The furnace temperature may be as low as 9000 F. for steel or even lower for other metals. For silicon steel the furnace temperature is 1500‹ F. and for magnetic steel 1475‹ F. The cooling rate is lower than free cooling in air at room temperature. A neutral or reducing atmosphere is preferable in the furnace.

Abstract: 1,147,170. Travelling cylinder printing machine. FARRINGTON BUSINESS MACHINES CORP. 4 Oct., 1966 [22 Oct., 1965], No. 44237/66. Heading B6C. A printing machine of the kind wherein an impression is made on a document placed over a raised-type printing plate has sensing means adapted to sense, by contact, the combined thickness of the printing plate and the document(s), and hence to automatically adjust the height of a platen assembly above the print bed. Fig. 1 illustrates a machine according to the invention; a base 21 is provided with a print bed which supports one or more printing plates 20, 24,25,on anvil support members 19, 22 and 23, the document 26 to be printed being placed over the printing plate(s). Two guide rails 28 and 29 in the base 21 direct bearings 31, (32) supporting travelling carriage 27, which comprises a pair of shoulders 33, 34, a handle 35, and a pair of platen assemblies 36 and 37 each individually rotatable about a shaft 38 which is received in the shoulders 33, 34, a stop bar 40 limiting the backward pivotal motion of each assembly. Each platen assembly, e.g. assembly 36, comprises a bracket 41 which through its side arms receives the shaft 38 and also a shaft 42 supporting a split roller platen 43; a sleeve 45 encompasses the rod shaft 38 and is provided with eccentric areas 46, and a sensing member 47 which has a curved end 48 is screwed at 50 to the sleeve 45 and is also tensioned by a spring 49 connected from screw 50 to the top of bracket 41. Assembly 37 is similar and operates independently from assembly 36. The operation of the sensing members, e.g. member 47, is illustrated in Figs. 3 and 4. In Fig. 3, the sensing member 47 is tensioned by spring 49 which rotates the member and the eccentric sleeve 45 in a counter-clockwise direction about shaft 38 until the sensing finger abuts the bottom horizontal edge of bracket 41; this position represents the "low level" sensing position where there is no printing plate below the platen assembly. As the carriage is moved in the X direction by means of handle 35 the lower surface 48 of the sensing member passes over a plate 24, moving the member in a clockwise direction; corresponding movement of eccentric sleeve 45 causes the mobile centre Q of eccentric area 46 to be raised above the centre of fixed rod 38, thus elevating the entire bracket 41 and the roller platen 43 relative to the print bed. Thus automatic compensation is provided for the varying thickness of documents and printing plates while the carriage traverses the machine; the roller platen is also locked in its elevated position by frictional forces during the application of printing pressure; when the printing pressure is eased, the platen and sensing member is automatically reset to the "low-level" reference position.
