Title: Apparatus for generating seismic waves
Inventor: WINBOW GRAHAM ARTHUR
IPC: G01V1/52
Filed: 1994-08-03
Abstract: The current invention is an apparatus useful for generating seismic waves with an enhanced signal to noise ratio. The enhanced signal is produced at a fundamental resonant frequency, and multiples thereof, by producing a near zero acoustic pressure condition in regions (A and C) around and beyond each end of the apparatus by either (1) using two end acoustic sources (22, 26) to produce a destructive interference effect with the acoustic output of a third acoustic source (24) positioned therebetween, or (2) using two active or passive end acoustic capacitors or resonators (Figure 2, not shown) to produce a near zero impedance condition at each end of the apparatus. The enhanced signal may be produced over a range of frequencies, including both resonant and non resonant frequencies, by creating a high impedance condition experienced by the intermediate source (24) and hence a high acoustic pressure around the intermediate region (B) of the apparatus. Preferably this high impedance condition is generated using one or more internal acoustic capacitors (32b, 36b) or resonators (72b, 76b) with each being positioned between the intermediate acoustic source (24) and an end acoustic source (22:26) or capacitor or resonator respectively. The apparatus can maintain the high impedance or resonant condition up to a frequency which is about two times the resonance frequency between the intermediate source and each internal acoustic capacitor. <IMAGE>

Title: Power controller of an induction motor
Inventor: POEPPEL JOSEF
IPC: H02P23/00
Filed: 1995-10-12
Abstract: A power controller of an induction motor C, L1, L2 with a main winding L1 and with an auxiliary winding L2 provides power control of the motor by means of a recurring digital word, such as from a ring counter 2. The auxiliary winding L2 has tappings N1, N2 and different power levels of the motor are set by the connection of the auxiliary winding or one of its sub-windings by means of triacs T1 - T4. Firstly a coarse adjustment of the power to be output by the motor is effected by the selection of a specified power level and at the same time for the fine adjustment a recurring digital m-bit keying pattern is generated by the ring counter 2 so that the motor is operated alternately with the set power level and with a next higher or next lower power level. This permits automatic power regulation. A microprocessor 3 carries out the coarse adjustment via a drive circuit 1 and at the same time generates the m-bit keying pattern which is stored in the ring counter 2. In alternative embodiments (Figs. 3 and 4) a single triac T1 connected to the main winding L1 is switched by the drive circuit 1. Further aspects relate to the microprocessor 3 and ring store 2. Uses include driving a pump, fan and hoist. <IMAGE>

Patent GB-953399-A (GB)
IPC: B65B51/14
Abstract: 953,399. Packaging machines. H. ALEXANDER. Nov. 14, 1962 [Aug. 25, 1961], No. 30673/61. Heading B8C. In a method of packaging an article 4, Fig. 1, with thermoplastic sheet material e.g. polyethylene, the latter is held between rectangular clamping frames 2, 3 and heated; the article is then passed through the initial plane of the sheet, Fig. 2, to form a tubular neck 6 which is sealed by sealing elements 8, 9. The latter may be vertically offset, Fig. 3, causing the sealed neck to be sheared, and freeing the packaged article from the web of thermoplastics material. Cooling of the sheet material about the article causes it to become a close fit therearound. In order to reduce the length of the line-seal air is extracted from the neck prior to sealing e.g. by placing a suction hood over the frame 2, or by inserting a suction tube into the neck. In the apparatus of Figs. 12 and 13 a web of thermoplastic sheet is fed from a roll 18 and held between rectangular frames 19 and 20. When a pedal 24 is depressed a fork 23 engages a stop 22 of a rod 21 to move downwardly the frame 20, thus allowing introduction of thermoplastic sheet 17 between the frames, sealing members 31, 32 are forced into their cocked position against the action of the counterweight 34, and are retained in that position by a plunger 36 engaging apertures 37; the pedal is then returned to its rest position. A heating member 25, running on rails 26, is moved into a position overlying the clamping frame, the sheet is heated and the heating member 25 returns to its rest position. An article is placed on the heated sheet, and extends the sheet before contacting a vertically mounted platform 48. A suction cover 40 is then brought into a position overlying the clamping frame, this action releasing a switch which allows the platform 48 to move vertically downwards until it reaches its lowermost position. The air is extracted, and then the sealing blades are released to effect sealing and shearing. The suction cover is returned to its rest position and as pedal 24 is again depressed a member 60 pushes the wrapped article on to a conveyer.

Title: Method for producing a pressure sensor
Inventor: GOEBEL ULRICH
IPC: G01L7/08
Filed: 1996-02-29
Abstract: A pressure sensor of the type having a sensing membrane and a closed reference volume is produced by uniting a ceramic plate 1, which is to form the membrane, to a shaped ceramic part 2 having a depression 4 which is to contain the reference volume. Around the depression 4 there is provided a thick-layer paste 5 which becomes hard after the assembly is fired. Preferably the paste does not completely surround the depression when it is applied to one of the parts, e.g. by screen printing. As a result, air can escape from the depression during firing and a subatmospheric pressure can thus be enclosed in the depression. As shown the assembly includes a further ceramic part 3 which provides a pressure inlet 6 to the membrane.

Title: Automatic database field identification eg for postal coding
Inventor: GARDNER DAVID P
IPC: G06F17/30
Filed: 1996-10-31
Abstract: A method of determining the nature of the contents of a data field. A field identification module (FIM) 102, scans the contents of the database 106 to determine a data field identifier for each of the data fields to be worked upon. The FIM 102 then compares each of the data field identifiers with a list of known identifiers stored in a repository 108 and assess a first score in respect of the comparison wherein the score is representative of a probability that the comparison is an accurate comparison. When a first probability score has been determined, the FIM 102 samples the data field according to a preselected list of requirements and make a second comparison with the data field. The FIM 102 then assesses a second score. After sampling the FIM 102 constructs a test case wherein the data field is used in the host application and a third comparison is made in respect of the test case. The FIM 102 then assesess a third score. The FIM 102 chooses a field type based on the weighted average result of the three scores and confirmed by a system operator. Once confirmed, the data field identifier and the data field represented thereby are added to the repository 108 as one of the known identifiers. The host application may be a postal coding system.
