Title: Automatically operating sphygmomanometer
IPC: A61B5/022
Filed: 1963-04-30
Abstract: 978,074. Sphygmomanometers. SIEMENS REINIGER WERKE A.G. April 30, 1963 [May 5, 1962 (2)], No. 17035/63. Heading A5K. An automatic sphygmomanometer, employing a pick-up for receiving pulse sounds during a measurement, has an amplifier which has a two-position control for increasing the gain from one valve, during setting up the equipment, to a second valve, for carrying out the actual measurements and / or means for automatically increasing the gain in a fixed ratio when changing over from diastolic to systolic measurement. The equipment comprises a control unit 11 which, at appropriate intervals, inflates a cuff 2 by means of a pump 20, records the diastolic pressure on a gauge 28, further increases the pressure above systolic and subsequently decreases the pressure slowly until the systolic pressure is recorded on a second gauge 29. Pulse sounds are detected by a microphone 3, the output from which passes through amplifier stages 4, 6 to a pulsing circuit 8 for controlling the unit 11. Since, under certain conditions of the patient, the initial pulse sounds at the diastolic and systolic pressures may be very faint, the equipment is set up with a control switch 40 moved to the left, so that the amplification gain is approximately halved. The cuff pressure is then allowed to fall through the systolic pressure until pulse indications are received and the pressure is dropped by a further 15 mm. Hg., at which point strong signals are obtained. The equipment is then adjusted as necessary, to give satisfactory recording, and, finally, before actual measurements are made, the switch 40 is returned to the position shown, where full gain of the amplifier is restored. It is also found that, in some eases, the pulse is much more difficult to detect at systolic pressure than at diastolic pressure. For this reason a switch 46, under control of the unit 11, is closed during diastolic measurement and opened during systolic measurement, thereby giving a predetermined greater gain during the latter. Specification 792,875 is referred to.

Title: Credit card and credit card identification system for automatic vending equipment
IPC: G06K7/00
Filed: 1974-05-04
Abstract: 1474114 Credit card verification W E CUTTILL and V M WAGNER 4 May 1974 [4 May 1973] 17041/74 Heading G4H A credit card verification system is designed to accept cards 22 bearing indicia in the form of inserts 23 or 23a having relatively high and low dielectric constants. The card may be of laminated plastics material containing the indicia therebetween; the indicia 23 may be covered by electrically conductive opaque material 33 so that their arrangement cannot be seen by a user of the card. The indicia are sensed by the circuit of Fig. 3 (and other figures, not shown) which includes a Schmitt trigger 52, and the resulting data is compared with data entered manually by the user. If there is agreement, then the apparatus incorporating the verification system (as described this is a vending machine) is enabled. The verification circuitry includes counters to count the numbers of successful or unsuccessful comparisons; in the event of too many unsuccessful comparisons an alarm signal is produced and the card is trapped in the machine. As described, the card contains an indicium LO which is used to check that the card has been correctly placed in the machine; it also contains embossed data used by the verification system to print a bill for the card user when he has completed his transactions.

Abstract: 844,397. Feeding sheets; grippers. FRANKFURTER MASCHINENBAU - AKTIENGESELLSCHAFT VORM. POKORNY & WITTEKIND. May 30, 1957 [May 23, 1957], No. 17254/57. Classes 100(1) and 100(2) A gripper device for feeding sheets comprises a fixed adjustable gripper jaw 12, a movable gripper jaw 7 which is forced by fluid pressure into contact with the jaw 12 to grip a sheet 13, and a tension spring 8 which resists the action of the fluid pressure on the jaw 7, the jaw 12 being hollow and in communication with a source of suction. Orifices are provided in the jaw 12 which communicate with the atmosphere in the absence of a sheet 13 and cause the sheet feeding mechanism to be rendered inoperative. As shown, a number of grippers arranged to swing about one of two tubes 6, 10 receive sheets 13 which have been separated from a pile and forward them to another point in a printing or other machine. Each gripper comprises a body portion provided with two recesses, one to receive the tubular support 12, which is clamped by means of a bolt 11 and provided with a hollow foot 14, and the other to receive a cylindrical piston 7 which is normally pulled inwardly of the body by the tension spring 8. A solid gripper plate 1 attached to the outer face of the piston 7 co-operates with a slotted gripper plate 2 on the foot 14, and when the two are in con tact, in the absence of a sheet 13, the slot in the plate 2 is not entirely covered, and the foot 14 and tube 12 are open to atmosphere. Fluid under pressure flows through the tube 10 and a passage 9 in the gripper body to the piston, and a source of suction applied to the tube 6 communicates with the tube 12 and hollow foot 14. If a sheet 13 is absent or improperly gripped by the plates 1, 2, this causes the sheet feeding mechanism to be stopped. The plates 1, 2 are readily replaceable, and can be covered with rubber.

Title: Process for the manufacture of ion-exchange condensation resins in pearl form
IPC: B01J39/19
Filed: 1958-06-02
Abstract: To make ion-exchange condensation resins in pearl form, the partial condensate is heated, to a temperature between 100 DEG  and 200 DEG C. to complete condensation, in admixture with a solution of a synthetic macromolecular dispersing agent in an inert organic liquid and water is removed azeotropically from the formed pearls. Suitable synthetic macromolecular dispersing agents are polystyrene, polyacrylates or polymethacrylates.  Ion-exchange resins may be formed according to the invention from the following components:-(a) phenolsulphonic acid, p-hydroxybenzyl sulphonic acid, benzaldehyde disulphonic acid, acetaldehyde disulphonic acid, a phenolcarboxylic acid, phenoxyacetic acid, a phenol, or a mixture of two or more of these subtances together with an aldehyde, (b) a polyalkylene polyamine, or polyalkylene imine together with epichlorhydrin or an aldehyde, (c) urea, a guanidine derivative or an amine or a mixture of two or more of such compounds together with an aldehyde. Preferred inert organic liquids are diphenyl ether and/or diphenyl, or diethyl benzene. In the Examples (1) A partial condensate prepared from phenol sulphonic acid, phenol and paraformaldehyde was stirred into a heated solution of polystyrene in a mixture of diphenyl ether and diphenyl and the dispersion was heated in 4-6 hours to 140 DEG C. with removal of water in a separator.  The mixture was cooled, filtered and polystyrene solution adhering to the pearls was removed by rinsing with benzene and methanol.  (2) A precondensate from resorcinol, chloroacetic acid, phenol, and formaldehyde was used. (3) A precondensate of polyethylene imine and epichlorhydrin was stirred into a solution of polystyrene in diethylbenzene and the mixture heated with liberation of water to yield pearls of the ion-exchange resin.  (4) A precondensate from m-phenylene diamine, formaldehyde, and polyethylene polyamine was brought to pearl form as in Example 1.
