IPC: B08B15/00
Filed: 1968-10-24
Abstract: 1,242,553. Impedance measuring bridge circuits. SAAB SCANIA A.B. Oct.24, 1968 [Oct.26, 1967], No.50485/68. Heading G1U. A bridge 1 providing an output voltage connectible with an indicator, corresponding to the resistive, capacitive and inductive impedance of transducer elements Z1, Z2 in the bridge, is mechanically and electrically connected with a reference unit 6 energized from the same source as the bridge to provide reference level outputs, at the same output impedances as the bridge when providing the same outputs. By comparing the bridge output with these reference levels the absolute values of the input physical variables to which the bridge responds may be deduced, irrespective of the particular supply voltage used. The reference unit contains reference circuits, with separate output terminals for each circuit, composed of passive components providing at least upper and lower reference signals corresponding to predetermined levels of excitation of the transducer elements. The reference unit 6 may contain a zero level output circuit R4, chosen to match the bridge output impedance at zero output, and an upper level reference circuit incorporating, in series across the bridge supply the resistors R5, R6 and R7 in parallel, and R8. A symmetrical output voltage is taken across R6, R7. The resistors R5-R10 are chosen and adjusted to correspond to the bridge output impedance when the bridge output is 50% of the maximum possible. The bridge and reference outputs can be switched alternately at 11 to a recording instrument 12. In an arrangement for calibrating a number of such measuring systems (15-17), Fig.3 (not shown) each associated with an individual reference unit (6) a physical stimulus (14) is applied to all the systems and to a standard reference system (18), all energized from the same source (19). Signals from the measuring systems are passed via switches (20-23) to corresponding matching units (24-27). The output from the reference system is passed to a comparator in a programme unit (30). At the 50% level as indicated by the standard circuit, each matching unit is adjusted to give the same reading. The stimulus is then progressively increased from zero and each time a given level is reached, as detected by the comparator the switch (28) is cycled and each of the measuring system outputs is passed to a voltmeter (29) and thence to a print out unit (31). The calibration curve for each circuit may then be derived.

A device which may serve. as a suspension bar for files or may be attached to a side edge of a suspended file to serve as a label holder has a channelled part with a lip engaged by a folded edge onthe file, the folded edge being inserted in a direction perpendicular to the length of the bar. In one form, Fig. 12, one edge of a suspended file is attached by rivets at 97, to a web 92 of the bar and the other edge or the, edge, of the next file is folded over and engaged with lips 95,on a web 94 spaced from the web 92. The webs 92, 94 are integral with a part at right angles thereto which, includes a label-receiving slot 90. The bar may be made of transparent plastic and the part 91 may be semi-cylindrical to act as a magnifying glass. An opening 93 in the web 92 facilitates the removal of the bar from the file. If the bar is used for suspension purposes it has hooks at its end. In another embodiment, Figs. 2-6, a web 7 attached to a flat part 6 has openings 8 along its length behind each of which is a web 9 with a lip 10 similar to parts 94, 95 and also for receiving a folded edge of the file. Between the openings 8 are other narrower openings 14 opposite to narrow flanges 15 on the part 6, the openings 14 serving to facilitate detachment of a bar. A label may be held on the part 6 by a transparent split sleeve. A bar somewhat similar to the bar 6, 7 but having a narrower top part 16, Figs. 7-9 (not shown), may be attached to the other edge of the file and can be nested in the bar 6, 7 as shown in Fig. 11 (not shown) to connect edges of adjacent files together. The ends of the webs 7 are thickened at 13; Fig. 6, to prevent relative endwise movement of the file and bar. The rods can be moulded in a core-less mould.

Filed: 1975-12-17
Abstract: 1537464 Data transmission; facsimile FUJITSU Ltd 17 Dec 1975 [23 Dec 1974] 51548/75 Heading H4P In a facsimile system groups of scan signals representing the black-white state of elementary areas of respective scan lines are generated. Each group is converted into a group of converted signals which include a reference bit at the start of the group. The converted signals are then runlength encoded. The encoding may be applied to two or more groups of converted signals at a time so that signals in the encoded group represent the state of elementary areas in corresponding positions in the two or more scan lines. The conversion may replace the first scan signal in each group to be converted by the reference bit, or the reference bit may merely precede that signal. In one arrangement, schematically illustrated in Fig. 2, in the conversion the scan signals (a) representing the first pair of elementary areas a, a n+1  in adjacent scan lines n, n + 1 are replaced (b) by reference bits both corresponding to white. The signals (b) are then encoded to provide run length and transition codes in alternating sequence, as indicated at (c), for transmission. The transmitted signal is decoded at the receiver. The transmitting and receiving circuits are described, Figs. 4-9 (not shown).
Patent GB-519751-A (GB)
Abstract: 519,751. Cash registers. NATIONAL CASH REGISTER CO., Ltd., and EALY, W. G. Sept. 30, 1938, No. 28500. [Class 106 (i)] Autographic arrangements; taking totals and subtotals.-In order to ensure that the amount in the cash drawer shall be recorded on an autographic strip prior to total-taking, an apertured shutter is moved over the strip to conceal previous entries and expose new portions of the strip. The invention is described as applied to a machine of the kind disclosed in Specification 259,478 [Class 106 (i)]. Prior to total-taking, the cash in the drawer is counted and the amount entered on an autographic strip 26, Fig. 1, through a slot in a hinged lid 48 and an aperture 45 in an endless flexible shutter 15 supported on rollers 16, 17. In the ensuing totaltaking operation, a shaft 1 is rocked and, through ratchet-mechanism and pin-wheels 10, advances the shutter to conceal the entry and expose a new portion of the strip beneath the aperture. This operation is repeated at the taking of subsequent totals until the aperture reaches the bottom of the slot in the lid. In the next succeeding operation, another aperture in the shutter arrives in operative position at the top of the slot and a fresh length of strip is drawn from a supply roll 28 and positioned over the platen 49 by the rotation of a'feed roller 20 against which the storage roll 27 is pressed. The feed roller 20 is connected by a spiral spring 21 to its spindle 14, Fig. 5, that is advanced one step at each operation by a pinion 13. Rotation of the feed roller is prevented by a detent 22 engaging a shoulder 23 until the spindle has made a complete revolution, when the detent is disabled by a pin 24 on the pinion, and the spring  21 rotates the roller to feed the strip. The rotation of the roller is limited to one revolution by the detent intercepting the stop, this being ensured by a guide surface 25 on the disc carrying the stop. To prevent the arrest of the strip by insertion of means through the aperture in the shutter, the aperture may be covered at this time by an auxiliary shutter situated at the top end of the slot in the lid 48 and oscillated at each operation.

Abstract: 1418914 Floor surfacings BAYER AG 13 Nov 1972 [13 Nov 1971] 52213/72 Heading E1G A substrate e.g. a floor is coated by applying to the substrate an aggregate, and then applying anhydrite as an inorganic binder in such a consistency that it forms a self levelling surface. The aggregate is preferably gravel which may be dry or in moist form. Other aggregate mentioned is pumice, expanded clay or mixtures thereof. The substrate may be a concrete floor which may have a separating layer consisting of a thin plastics sheet placed thereover. Penetration of the binder through the layer of aggregate can be promoted by using vibrators. A thin layer of binder which may be cement or synthetic resin may be initially applied to the floor before scattering of the aggregate before applying the final coating of binder. The aggregate may be applied as a mortar of cement and aggregate or synthetic resin and aggregate. In an example a layer consisting of gravel and a polyurethane binder is first applied, followed by a layer containing 100 parts anhydrite, 28 parts water, 2 parts activator, 0.5 parts anionic melamine resin.
