Title: Credit control system
IPC: G06Q20/40
Filed: 1971-08-25
Abstract: 1352600 Credit control system TRW DATA SYSTEMS Inc 25 Aug 1971 [28 Dec 1970] 39936/71 Headings G4A and G4T A credit control system for use in a department store has a memory 131 such as a magnetic disc containing data identifying a customer, his credit status, his credit limit and his accumulated balance. In the event of a credit transaction an operator at one of a plurality of keyboards 10 enters the customer's account number and the purchase amount. The entered digits are accumulated in a buffer module 110a, 110b each of which is coupled to e.g. 10 keyboards. The buffers feed a communication adapter module 111 which collects data and provides timing and control signals for telephone line transmission via modems 14, 15 and scans the buffer modules to see which is ready for transmission. The data is fed to a central processor 13 which may contain several processor units and the digits are checked for error. The data is allotted to a processor and the account number is checked with stored numbers until identity is obtained. The customer status is checked to see if the purchase may continue and the balance, credit limit and purchase amount are checked to see if the credit limit is exceeded. If the purchase is valid a green light is illuminated on the operator's keyboard, the account is updated and the purchase completed. If the customer's number is not in the store he is assigned a standard credit limit, the purchase is checked against the limit and if valid allowed to proceed. A restricted credit status causes a signal to be sent to the operator indicating that the purchase may not proceed. If the credit balance plus purchase price exceeds the credit limit a yellow status code is returned to the keyboard to operate a yellow indicator lamp and to activate an authorizer unit 12 in the credit office. This has a control and display unit 121 and, if required, a printer 123 and allows an operator to update, delete or add an account or to change the credit or status of an account. If a credit limit is exceeded credit may be cleared for a single transaction to allow the purchase to proceed. Amounts may be added to or subtracted from a balance. The stored data may be updated e.g. at the beginning of each month using cards or a magnetic tape which holds all new information, which is transferred to the data storage unit 131.

Abstract: 835,973. Non-inductive wound resistors. ELECTROTHERMAL ENGINEERING Ltd. Dec. 23, 1958 [Dec. 23, 1957], No. 39956/57. Class 37. A low inductance wound resistor has a path of conductive material situated very close to the winding so as to influence the current flow through the resistor when its value is changing. Figs. 1 and 2 show a resistor having a cylindrical body 1 of insulating material and flanges 2, 3 so that sections 5 and 6 are provided into which the resistance wire is wound. The core is coated with silver at 9, 10 and 11 which is preferably covered with an insulating varnish. Instead of silver the conducting material may be gold or copper or the core itself may be made of a conductive material such as copper and covered with insulation, for example sprayed on ceramic coating. The resistance wire is itself wound, for example by a bi-filar or reversed section method, so as to minimize its inductive effect. Thus the bi-filar winding may be wound in one direction in section 5 and in the opposite direction in section 6, the turns in each being equal. In a modification the silver covering 10 is removed from the core between the lines at A and B and also between the lines C and D, thus dividing the silvering into three sections, the central section of which is earthed. In a modification shown in Fig. 3 the core of insulating material is provided with copper collars 15 fitting closely round the stem of the core and discs 16 which are split and joined so as to form a conductive loop round the magnetic axis of the resistor. The collars or disc could be used alone and are preferably coated with an insulating material. In a further modification the core is. provided with a conductive sleeve of solid metal or a conductive paint, fitting closely to the windings. The resistance wire which is insulated is connected to the conductive path at one point such as the centre of the winding or at one end. A resistive strip or ribbon may be used in place of wire or a wire winding may be simulated by coating a cylindrical former with a thin layer of conductive material and machining so that a helix of conductive material is left on the former. Specification 5171/01 is referred to.

Alternate fields of the output of mixing means 2 may then be recorded on the magnetic tape, or the output of mixing means 2 may be fed to a switching means 6 directly and via a one field delay means 7 and half-line period delay means 8, switching means 6 operating to pass to output terminal 9 alternately two fields of the undelayed signal from mixing means 2 and two fields of the delayed signal from delay means 8; alternate fields of the signal at output terminal 9 are recorded on the magnetic tape. In an alternative embodiment a gate circuit (12, Fig. 5, not shown) which passes only every fourth field that it receives is inserted between delay means 4 and mixing means 2. When a television signal at 60 fields per second derived from a film moved at 24 frames per second, where alternate film frames are scanned by two fields and the intervening film frames are scanned by three fields, is recorded as in the embodiment of Fig. 3 (or that of Fig. 5, not shown) the signal to be recorded does not include, as the main signal fed directly to mixing means 2, a signal derived from each eighth film frame. To ensure that a signal derived from every film frame is recorded, as the main signal, the output of delay means 4 is fed directly to switching means 6 and is selected as the output to terminal 9 every twenty-first field to insert the nineteenth field (which is derived from the eighth film frame) into the recorded signal. When the signal to be recorded is a colour television signal a low-pass filter 3 is included to remove the chrominance component from the signal to be delayed, a similar filter being included for delay means 7. On playback each recorded field is reproduced twice. The delay means 4 and 7 are formed by a magnetic disc (13, Fig. 9, not shown) rotating at 54 revolutions per second.

In a rotary shaft seal comprising a rubber ring 11 that grips the shaft 110 and has an integral annular sealing lip 19 at one end engaging a radial face 111 on the shaft housing 112 the lip is formed by a circumferential groove or cut 16 in the ring and has, in its free state, a frusto-conical inner surface 15 with a base angle of between 30 degrees and 60 degrees. The free inner diameter 12 of the ring is less than the shaft diameter so that when mounted it tightly grips the shaft and the force with which the lip 19 engages the face 111 may be varied by axial adjustment of the ring 11 on the shaft and may be such that at a predetermined shaft speed the lip yields under centrifugal force and no longer contacts the face 111. The ring may be made by press-fitting a rubber tube on a wooden rod, rotating the rod, feeding a tool at an angle to the rod axis to cut the tube into rings having conical end faces 14, 15 and then grinding or cutting the V-shaped groove 16 in each ring. In a modification, Fig. 4, the groove 16 is replaced by a cut 26 which, when the ring is mounted on the shaft 210, is opened by providing a groove 213 in the shaft adjacent the part 214 of the ring.
