Abstract: 1436787 Detecting the presence of liquids; sound producing instruments W VOLL [trading as EKTRONIK ING-GRAD WALTER VOLL] 13 Dec 1973 [21 Dec 1972] 57759/73 Heading G1N Also in Division G5] An audible alarm for indicating the presence of a liquid comprises a pair of electrodes controlling a "transistorized buzzer". Circuits are given for response to a conducting or alternatively a dielelectric liquid bridging the contacts. Applications:- rain detector; floating floodwarming; or a tank-fitting liquid-level-limit indicator. CONSTRUCTION FIG. 1 comprises a twopart spheroid housing 1 with flat upper and lower portions to stand on a horizontal surface.  Annular electrodes 2 are mounted externally around the lower casing, which houses batteries 5 and circuitry below the metal diaphragm 5 and circuitry below the metal diaphragm 11 of a "loudspeaker". The unit will float in a flood, or may be invented as a rain detector. Alternatively the electrodes 2 may be mounted on a rod depending from the housing for insertion into a tank Fig AUDIO OSCILLATOR CIRCUIT FIG. 2. The speaker unit has a main drive winding 8 and a feedback winding 9 which are connected in circuit with transistor T3 as an audio-frequency blocking oscillafor. This audio-oscillator is pulse-energized by an R.C. oscillator comprising T<SP>1</SP> 1 , T 2  which is switched on by water bridging contacts 2, thus providing a modulated audio-tone. DIELECTRIC SWITCHING CIRCUIT FIG. 3. Provides additional stages T4. .T 7  to switch on the circuit of Fig. 2. The electrodes C 2  form a capacitor in an R.C. oscillator circuit T 6 , T 7 , whose output controls Ts to repeatedly discharge capacitor C4. When the electrodes C 2  sense a dielectric liquid the oscillator frequency and hence the discharge rate decreases allowing capacitor C 4  to charge to a higher voltage and switch on the audio oscillator T 1 ..T 3 .

An electronic desk-top computer system has at least two stations, each with a keyboard and a data-output device, and a separate store associated with each to receive input and result values of that station, a single computing and control device (e.g. at a central station) and means for connecting one station at a time with its associated store to the computing and control device. The connecting means may be controlled by a distributer or manual keys. Besides communicating with the central station and with each other via the central station, the stores may be able to communicate with each other direct. When one station is connected to the central station, information fed into other stations is not lost. Each store may be a plugin module and is a recirculating delay line (or a magnetic core store) and may be at its respective station or at the central station. In the latter case the stores may provide or extend a store associated with the central station. A plurality of delay lines may be connected in parallel to give a larger store.

Abstract: 1298080 Elastic binders BERGER BROS CO 10 Dec 1969 [24 Dec 1968] 60246/69 Heading A5R [Also in Division A3] An elastic binder 10 is formed of elastic strips 11 which are elastic lengthwise and substantially inelastic widthwise, the strips being joined together lengthwise in pairs to form combined strips which are then joined in pairs at measured intervals along their lengths with the strips overlapped, and means are secured to the ends of the binder to join the ends together in body-encircling form. The pairs of elastic strips are joined together by two elastic bands 12 stitched along their lengthwise edges to the elastic strips; the elastic bands are also joined at their midpoints 14 to form a double lip, Fig. 5. The elastic strips may alternatively be joined by overlapping them and stitching them together directly (Fig. 6, not shown). The two combined strips are overlapped and the free edge of one combined strip is stitched at measured intervals 16 to the other combined strip. The free edge of the second strip is cut away in a parabolic curve 17 to reduce the thickness of the binder. In use this cut-away portion is placed over the injury, thus reducing pressure thereon. The ends 19 of the binder 10 are cut so that one edge is shorter than the other edge to ensure that the binder fits well around the body part. A tape 21 with a row of hooks 23 is sewn inside the binder at one end and a tape 20 with two rows of eyes 22 is sewn outside the binder at the other end, for securing the binder around the body part.

Abstract: 664,617. Testing physical qualities. COX, H. L. April 6, 1950 [April 6, 1949], No. 9389/49. Class 106 (ii). [Also in Group XXIV] Mechanism for producing a small vibrational movement of variable amplitude for use, e.g., in fatigue testing, comprises a rocking lever to the ends of which are imparted vibrations in the same plane, of the same frequency, of constant amplitudes, but of relatively variable phase, the required vibrational movement being taken from a point on the lever dividing its length in the same ratio as the ratio of the amplitudes of the vibrations imparted to its ends. A rocking lever 1 is coupled at its mid-point 2 to the object to be vibrated and its ends are vibrated by slider crank chains comprising sliders 3s, 4s and connecting-rods 3c, 4c actuated by crank-shafts 3, 4 of equal throw, the shaft 3 being driven, for example, by an electric motor 10 and driving the shaft 4 through a coupling adapted for changing the relative phase of the shafts 3, 4 without interrupting the drive.

In various modifications the liner parts A, B, C and D may be formed and inserted into the cylinder as separate components, the liner part A either being flangeless or including a part of flange 33. The configuration B, C, D, may be provided on an integral part of the cylinder block 21 or formed on a short insert in the upper part of block only. The parts A, B, C, D, may be formed directly in the cylinder block or the inclined surface D may be dispensed with and a single stepped bore provided; the surface C could be oppositely inclined to surface D and the parts B and C may be of the same diameter or the part D dispensed with and the surface C made tapered.

Title: Rotary mower with thatch-cutting means
IPC: A01D34/73
Filed: 1978-06-01
Abstract: This invention adds a further facility to a vertical shafted rotary lawn mower. The quality of a lawn is improved by controlling those elements of a lawn's population which have part of their growth horizontal, thus giving more chance to the upstanding leaf grasses, which would, otherwise, be choked off by the more robust elements-rye grasses, clover, etc. This is achieved by the addition, to the mowing cutter bar 12, of blade(s) 10, which whether they be integral or adjustable, fixed or pivotally mounted, protrude vertically downwards below the plane of the mowing blades. The effect of these additional blade(s) is to sever a large proportion of the horizontal growths right down to soil level, while leaving most of the upstanding grass untouched, apart from being mown to length by the conventional part of the mower. <IMAGE>

Title: Printing press make ready and control system
IPC: B41F31/02
Filed: 1979-06-01
Abstract: A system is disclosed for making ready and otherwise controlling a printing press. Data is gathered relating to the configuration of the press being controlled from PIM, REP etc., and also to certain other parameters required for presetting and otherwise controlling the various mechanical settings on the press. A number of dedicated microprocessors, each associated with one type of mechanical setting (i.e., ink fountains, water fountains, registration elements, etc.), process this data in order to derive control information therefrom. These processors then cause an associated control circuit to preset the corresponding mechanical settings as determined by this processing using feedback control. Facilities are also provided for an operator to view the various presets and to make changes therein. Positions of the ink keys, used to regulate the flow of ink, for instance, are adjusted in dependence upon the print density in the column of print corresponding to each key. The density is measured in a scanner processor PIM which illuminates each column in turn of a film representing the page of print and determines the density by the amount of light transmitted. The setting parameters for more than one run using different material on the same machine may be worked out in advance in processors RC1, RC2 and stored at 70. <IMAGE>
