Title: Digital filter
IPC: H03H17/04
Filed: 1971-12-06
Abstract: 1346698 Active filters INTERNATIONAL BUSINESS MACHINES CORP 6 Dec 1971 [17 Dec 1970] 56457/71 Heading H3U A digital filter comprises a store containing numerical values, addressing means responsive to address digits derived from the input signals to read from the store a succession of selected numerical values, and arithmetic means to sum each succession of values. A recursive filter, Fig. 3, comprises a forward path delay C3 connected to input X and feedback delays C1, C2 which provide, suitable address signals for store 12 which holds 16 words each of B bits. The B bit output is applied in parallel to an adder 14 which is part of a loop comprising a clock controlled gate 16 and halver 18. If, in order to deal with negative signals, a modified two's complement internal code (C1M) is used for the signals, then the store need only contain eight addresses with provision for changing the sign of the output to give the positive or negative value of the contents. This sign changing is effected by the provision of EXCLUSIVE-OR gates XOR1 ..... XOR4 which, whenever a "1" occurs on line 1, inverts the sign applied to the other input. The arrangement may be used for delta modulated signals by including suitable converters in the input and output, Fig. 4 (not shown). A non-recursive arrangement is also described, Fig. 5 (not shown).

Title: Orally administrable corticosteroid preparations
IPC: A61K9/24
Filed: 1973-12-10
Abstract: 1458676 Corticosteroid compositions HOECHST AG 10 Dec 1973 [9 Dec 1972] 57090/73 Heading A5B A controlled release unit dosage pharmaceutical composition for oral administration comprises at least two layers, the word "layer" including a core in its meaning (e.g. drageÚ cores), each comprising a corticosteroid in the form of the free alcohol or an ester or salt thereof and each having different release properties. The corticosteroid may be hydrocortisone, cortisone, prednisone, prednisolone, methylprednisolone, or esters or salts thereof. Each layer may contain the same or different corti- 'costeroids, e.g. prednisolone in one layer and its acetate in another, or cortisone acetate in one layer and prednisolone in another. The preferred form is a dregÚe core such as a pressed tablet as the one corticosteroid-containing layer, having an enteric coat (e.g. cellulose acetate phthalate) resistant to gastric juice but soluble in the dudodenum, and an outer dragÚe coating containing corticosteroid, this coating being freely soluble in gastric juice to liberate its active ingredient for absorption in the stomach. The compositions are intended to enable the corticosteroid to be administered in such a way that its absorption rate and action is synchronised with the circadian rhythm of physiological ACTH secretion, and accordingly, the preferred form provides a small steroid dose immediately (i.e. from the outer, soluble layer), and a larger dose some hours later (i.e. from the inner, enterically coated layer), the dosage form being intended to be taken early in the morning. The invention includes a pack comprising a card carrying at least one pair of inventive unit dosage forms together with instruction that one unit is to be taken at about breakfast time and the other unit is to be taken between midafternoon and bed-time.

Title: Measuring gauges with contact feelers

Filed: 1971-12-29
Abstract: 1382060 Measuring dimensions electrically M POSSATI [trading as APPARECCHI ELECTTRONICI MARPOSS] 29 Dec 1971 [29 Dec 1970] 60553/71 Heading G1N A gauge for measuring orthogonal dimensions of a workpiece with two pairs of feelers disposed at right angles is provided with means for correcting the measurements for errors arising from misplacement of the measuring gauge relative to the workpiece. As shown a gauge centred at P is used to measure the internal diameters of a hole 12 in workpiece by feelers associated with transducers and having semicircular ends 26, 27, 28, 29. The measurements 16, 17, obtained for the vertical diameter are shown to be short by an error factor e = (19-18)<SP>2</SP>/4(R-r) where 19 and 18 are the values obtained for the horizontal diameter. Fig.4 discloses an arrangement for obtaining a signal representative of this error from signals representing the outputs for 18 and 19. The signal 18 is fed at 53 and inverted by an operational amplifier 72. This output and the signal 19 are fed via equal resistors 78, 79 to an amplifier 82 having a gain of 0À5 giving (19-18)/2. A circuit 86 provides that a positive signal of this circuit arises at point 102. To obtain the quadratic term (19-18)<SP>2</SP>/4 which has a parabolic characteristic, a circuit comprising parallel paths 104, 106-107, 108-109, and amplifier 111 are provided, the paths providing linear portions approximating to the desired parabola. The output of the amplifier gives the error signal which is added to the signals 16, 17 in summer 116 to give the desired vertical diameter. A similar circuit may be utilized to measure the diameter of a shaft whose axis is angularly displaced from the medium line of two pairs of displaced feelers Fig.6 (not shown).

The invention is embodied in a machine of the Allen-Wales type having means for adding and subtracting and for recording items as described in Specification 598,524. The pence denomination only is described, known means being provided for entering tenshillings. The " 10 " and " 11 " keys .127 of the pence denomination are each mounted on a shortened key-stem 139 secured by a bent extension 137 to a key-stem 126 slidably mounted in alignment with the key-stems 26 of the " 1 " to " 9 " keys 27. The differential stop-bar 44 and an auxiliary stop-bar 135, secured thereto and spaced therefrom by collars, have series of abutments 61 and 134 respectively which co-operate with legs 31 and 131 formed on the key-stems 26 and 126 respectively so as to position the stop-bar 44 in accordance with the value of the depressed key. The additional steps of movement are accommodated by the provision of additional teeth in the totaliser pinion and additional type in the type bar. In the subtraction mechanism, the shape of the arm (not shown), the movement of which is complementary with respect to the movement of the stop-bar, is modified. The key-stems in each denomination have notches which cooperate in known manner with a bail 38 controlling a zero stop for the stop-bar and with a latching bail 37 while projections 148 on the key-stems are engageable by a locking rail 49.

Patent GB-730150-A (GB)
Abstract: 730,150. Linear-dimension gauges. JOHNSON GAGE DEVELOPMENT CO. Aug. 17, 1953 [Sept. 16, 1952], No. 22570/53. Class 106 (2). A contractible plug gauge comprises two arcuate shaped parts 10 and 11, Fig. 1, pivoted together at or near their edge along an axis 19 parallel to the longitudinal axis of each of the parts 10 and 11. The resultant plug gauge may be cylindrical or tapered and it may have a plain or a threaded surface. As shown, the parts 10 and 11 are mounted on arms 20 biased apart by a spring 21, the lower arm being pivoted at 24 to the base of a stand 23 whilst the upper arm actuates a dial gauge 25 supported by the stand. For hand operation, the arms 20 are detached from the stand 23 and use is made of a catch having two arms 35 and 38 of different lengths co-operating with a stop 37 to set the parts 10 and 11 to " go " and " notgo " dimensions. Fig. 4 illustrates an alternative spring arrangement 43 for biasing the arms 20 apart. In an alternative arrangement, Figs. 5 and 6, the gauge is shown with the pivot axis 48 of the parts 10 and 11 at the boundary surface of said parts. The members 10 and 11 are each secured to separate bearing members 45 each having a bearing surface 46 which is less than a semicircle in cross-section. The two bearing members 45 are mounted on opposite sides of a cylindrical pivot 47 which is in the form of a disc and upon which the bearing surfaces 46 ride to pivotally mount the parts 10 and 11 on the pivot axis 48. The bearings 45- are longer than the pivot 47 so that the gauging members may have longitudinal movement with respect to each other. A spring 21 biases the parts 10 and 11 to the closed and open position after they have been set to such positions. Gauging members may extend from both sides of the arms 20, 21 as shown in Figs. 2 and 6. On one side, the thread or gauging surface 13 may be a full thread to provide a " go " gauge and on the other end the gauging surface 30 may have one or two truncated threads engaging at the pitch diameter and providing a. " not-go " gauge.
