Title: Improvements in or relating to pastille formulations
IPC: A61K9/24
Filed: 1966-11-24
Abstract: 1,144,915. Pastilles. ARMOUR PHARMACEUTICAL CO. Ltd. and R. B. CHRISTIE. 23 Nov., 1967 [24 Nov., 1966], No. 52599/66. Heading A5B. A pharmaceutical pastille is composed of two parts which dissolve in the mouth at dissimilar rates. The two parts may be present as layers "side by side" or one may be present as a coating overlying the other. The pastilles may be employed as antitussives, when the more rapidly dissolved layer may comprise such substances as dextromethorphan, phenylpropanolamine, ephedrine HC1, pheniramine maleate, benzocaine, hyoscine HBr, isoprenaline sulphate, eucalyptus oil, menthol and thymol, and the more slowly dissolved layer may comprise NH 4 Cl, glycerol guaiacolate, syrup of tolu, extract of squill, extract of ipecacuanha, sodium benzoate, cresol, phenol, BiCO 3 , AI(OH) 3 , p-chlorophenol. The base may comprise sugar, glucose, gelatin and tartaric acid in varying proportions.

Title: Signalling set for bothway dc signalling between telephone  exchanges
IPC: H04Q1/38
Filed: 1972-11-15
Abstract: 1405161 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 15 Nov 1972 52855/72 Heading H4K The SCDC (single commutation direct current) method of signalling over interchange junctions is modified by the provision of only one double winding relay for use in both directions of transmission. The method is fully discussed at p. 668 of Telephony Vol. II by J. Atkinson but sufficient of its details should be apparent from the following description. In the Figure the B subscriber is connected through not-shown slection stages to a line transformer TR2, dialling impulse repeating relay A2 and a conventional SCDC bothway-signalling relay set IN 2, OUT 2, 02, I2. The A subscriber is similarly connected to a modified relay set in which a single relay R1 serves in place of the two relays IN 2, OUT 2 of the conventional set. Outgoing call A # B.-In response to looping of the caller's line, A1 comes up followed by slow-to-release relay 01 through its winding I. Positive potential is thus connected to junction wire La via a path that bypasses one of the shown diodes while negative potential is applied through the other (lower) diode to junction wire Lb. Relay R1 remains back. At the called end, polarized relay IN 2 comes-up and indicates the fact of an incoming call over wire INC. Relay I2 follows to busy the relay set against seizure for outgoing traffic. Dialled digits are repeated by relay A1 as polarity reversals on the junction wires to a register coupled to the wire INC of the incoming relay set. When the called party replies, his time relay A2 comes up so as to connect positive battery to the mid-point of windings I, II of his relay IN 2, The latter holds but the change of potential on junction wire Lb is effective to bring up relay R1 in the callers outgoing relay set whereby an answering signal is transmitted over his B-ANSW wire. Outgoing call B # A.-Looping of B's line brings up A2 whereby 02 follows to busy the set against incoming calls by locking out IN 2 and also druing dialling by virtue of its slow-torelease characteristic. In addition positive and negative battery are applied to junction wires La, Lb respectively via the windings of relay OUT 2. Relay R1 in the incoming relay set comes up so as to give notice of the incoming call on wire INC and relay I1 follows to busy the relay set. Dialling and answer supervision follow as before.

Title: Flexible vane regenerative rotary pump
Inventor: EBSARY VIVIAN RICHARD
IPC: F04C5/00
Filed: 1970-11-06
Abstract: 1286575 Circumferential flow pumps; flexible vane pumps V R EBSARY 6 Nov 1970 [6 Nov 1969] 52961/70 Headings F1C and F1F A circumferential-flow pump comprises an inlet port 3 and an outlet port 4 dividing the peripheral wall of the pump chamber 2 into a major arc and a minor arc, and flexible impeller vanes 13 of elastomeric material which have a flow clearance with the pump chamber except along the minor arc where a working clearance only is provided. The working clearance is afforded by a flexible plate 14 which normally lies against the peripheral wall. When the pump is to be primed, a plunger 16 is depressed to deflect the flexible plate 14 into the attitude shown. The resultant deflection of the vanes 13 as they pass the plate 14 causes a temporary reduction in the inter-vane volume. The subsequent restoration to normal volume when the vanes pass beyond the plate 14 creates a suction effect at the inlet port to effect priming. A vent passage 19 in the plunger co-operates with a vent passage 18 in the plate 14 to vent the pump chamber to atmosphere only when the plunger is depressed. The vanes may be provided at the side, or both sides, of the impeller, a laterally disposed flexible plate, or plates then being provided. The flexible plate may be omitted, the plunger then having a tapered nosing to contact the vanes. The plunger may also be omitted, the chamber 2 then being of reduced dimensions along the aforesaid minor arc to provide the working clearance. In this case, a priming reservoir is provided. Where immediate cessation of flow is required without stopping the pump, the vanes are made more flexible so that they deflect to provide the effect of a by-pass valve.

Contacts 5 are retained in bores in an insulating housing 3 by resilient rings 21 which are wedged into grooves 8 in the contacts 5 by forward movement of a rear insulating block 13. The block 13, a resilient cable grip 23, a washer 27 and a pressure ring 25 are surrounded by a sleeve 18 which threadably engages an outer casing 1 secured to the housing 3. As shown, each ring 21 is split and of circular cross-section wire, and is pushed into its contact groove 8 by the forward edge of a boss 14 on the block 13. In modifications, further rings (122, Figs. 5-8, not shown) or cylinders (123, Fig. 9, not shown) are located at the forward surface of the rear block (114 or 113), and the rings 21 are replaced by split cylindrical collars (29, Figs. 10-12, not shown).

[Class 106 (i) ] A calculating machine with add and subtract totalizers has a transfer mechanism therefor operable in either direction of movement to impart an additional step of movement to the actuating mechanism through a transfer conditioning member, one for each denomination, which is actuated by a transfer with or abutment on the adjacent totalizer wheel, the width of the abutment and conditioning member at the point of contact subtending an angle at the centre of the wheel equal to the digital spacing on the wheel. The machine described is of the type set forth in Specification 540,283 and includes similar keyboard mechanism, differential actuating mechanism, printing mechanism, total and subtotal taking mechanism and operating mechanism. Totalizer selecting mechanism.-In one form as shown in Figs. 3 and 4, two totalizers 173 are provided, the spindles 174 of which extend through slots in the partition plates and through inclined slots 178a in spring-controlled slide bars 179, 180. The slide bars are provided with pins 305, 306, that co-operate with operating levers (not shown). The totalizers may be circumferentially arranged around an operating gear and be selected in the manner described in Specification 540,311. Transfer mechanism.-The lower rack 14, Fig. 3 of each denomination of the differential mechanism is normally locked against movement but is freed for limited movement in either direction at transfer by rocking a transfer member 206 to move its pin to one or other end of a zig-zag slot 210 in the rack 14. The transfer member is formed with arms 204, 205 to co-operate with an abutment 216 on a disc 215 secured to the totalizer wheel of next lower denomination. When the transfer member is rocked a pin 214 thereon holds it in one or other adjusted position by engaging a slotted transfer latch 185 operatively connected to an arm 184 controlled by pins 182, 183 on the slides 179, 180. By this means the parts are restored at the end of the return stroke or forward stroke depending on whether addition or subtraction is being performed.
