Title: Improvements in or relating to venetian blinds
IPC: E06B9/28
Filed: 1953-01-28
Abstract: 719,050. Venetian blinds. VENETIAN VOGUE, Ltd. Jan. 28, 1953, No. 2448/53. Class 20 (3) A venetian blind is mounted so as to be extensible in a non-vertical direction by supporting the lath assembly or means comprising runners, slides, or the like, mounted on guide rails arranged parallel to the path of movement of the blind laths so that the blind when extended is supported at a plurality of points throughout its length. The venetian blind, fitted to a skylight 1, comprises laths 2, connected by ladder tapes 3 secured at one end to a tilt rail 4 and at their free ends to a support rail 5, the blind being operated from an extended to a nested position by the usual arrangement of pull cords 17. The tilt rail 4 is provided at its ends with pivot pins 6' one of which is supported on a bracket 7 secured to a head rail 10, whilst the other pin 6 is connected to geared tilting mechanism 8 secured to the head rail 10 and operable by pull cords 9. Guide wires 11, provided with adjustable tensioning means, not shown, are arranged in line with, and below, the tapes 3 each guide wire being anchored at opposite ends to an eyelet 12 screwed into the skylight frame 1. Eyelets 16, attached, e.g. by stitching, to the tapes are slidably mounted on the guide wires 11 to support the lath assembly and permit angular adjustment of the laths 2. The lath assembly is moved automatically upon release of the pull cords 17 by a pair of counterweights 21 each of which is connected to the support rail 5 by a cord 22 which passes over a pulley 23. The axes of the pulleys 23 are preferably located below the plane of the guide wires 11 so that the upper tape 3 is held taut and the lath assembly is held in correct relationship to the plane of the skylight. In an alternative construction where the counterweights are omitted the runners are fitted to the guides 11 to form rigid supports for the lath assembly to prevent the laths from collapsing on to the guide rails.

Title: Value dispensing system
IPC: G07F7/08
Filed: 1975-01-20
Abstract: 1464703 Selective signalling OMRON TATEISI ELECTRONICS CO 20 Jan 1975 [1 Feb 1974] 2455/75 Heading G4H A system for automatically dispensing value comprises means for reading from a customer's card, the number and current off-line balance of the customer's account, means for setting an amount of value to be dispensed, means for storing the current on-line balance of the account of each customer, first determining means for determining whether said amount is to be dispensed by comparing the amount with one of the off-line balance and on-line balance, second determining means for determining whether said amount is to be dispensed by comparing the amount with the other of the two balances, and means controlled by the first determining, means to render the second determining means operative. A cash dispensing terminal can be manually set into an on-line or off-line mode. Assuming it is set to the on-line mode, a secret number read from the customer's card is compared with a memorized number entered manually. Assuming equality, the customer is requested to enter the amount required manually, and this amount information and his savings' account number read from the card are sent to a remote CPU where the account number is used to access the on-line balance of the account from a store. The CPU compares the amount required and the online balance, and if the latter is sufficient, the stored balance is updated and the terminal is signalled to dispense the cash. On the other hand, if the on-line balance is not sufficient, the terminal is signalled to switch to the off-line mode. In the off-line mode (which is also used when the CPU is not in use), the terminal compares the amount required with the off-line balance read from the card and if this balance is sufficient it is updated on the card and the cash is dispensed, whereas if it is not sufficient, cash is not dispensed. Whether cash is dispensed or not, the card is returned to the customer. By inserting his card and pressing a reference button, the customer can cause his on-line and off-line balances to be displayed at the terminal (the online balance being obtained from the store associated with the CPU using the account number from the card and the off-line balance being obtained from the card): this enables the customer to obtain a required sum partially from his on-line balance and partially from his off-line balance by using the respective modes in turn, which is useful if neither balance alone is sufficient but both together are. Alternatively such a sum can be obtained from the two balances automatically. The system is also applicable to giving credits or cash loans, or vending articles or services.

Title: Improvements in the control of electric generating plant
IPC: H02P9/00
Filed: 1926-02-02
Abstract: 274,921. English Electric Co., Ltd., and Deriaz, P. Feb. 2, 1926. Regulation, automatic.-An electric generator 1 driven by a prime-mover such as a hydraulic turbine is regulated for constant power output by a centrifugal governor 5 operating upon a rheostat 3 in circuit with the field winding 2. The control member of the prime-mover is set for as efficient operation as possible, and should the load resistance increase so that the current decreases, the set will increase in speed, and the governor will increase the field so that the voltage of the generator is increased both by the increase in speed and also by the increase in excitation and thus the power output is restored to its constant value. A separate field winding 7 prevents the set running away should the governor 5 fail. Also the governor 5 or a separate governor may act upon the control of the prime.mover outside the range in which the rheostat 3 normally functions.

Abstract: 762,292. Connecting and eccentric rods. GRATZMULLER, J. L. Feb. 5, 1954 [Feb. 5, 1953], No. 3456/54. Class 122 (1). A driving connection between a rotary shaft A and a reciprocating element, such as a pump plunger 21, comprises a disc member 27 pro. vided with two parallel bores 28a and 32 in which are journalled respectively the shaft crank or eccentric 28 and a pin 31 having a diametral bore 31a in which the plunger, after passing through a segmental slot 27a in the member 27, enters with substantial clearance, the end of the plunger and the pin 31 being pivotally connected by a gudgeon pin 33 housed in a bore 33a at right angles to the bore 31a and passing through a hole 33b in the plunger 21 and the slot 27a being deep enough to accommodate the angular movement between the plunger and the member 27. The pin 33 is inserted when the plunger is at one extremity of its angular movement in the slot 27a and removed, when the plunger is in a similar position, through a bore 34 in the member 27 which is then aligned with the bore 33a. As the normal angular movement of the plunger is less than that allowed by the slot 27a, the pin 33 is consequently locked in position.
