Title: System for verifying the identity of a person
IPC: G07C9/00
Filed: 1977-02-21
Abstract: 1532944 Verification NCR CORP 21 Feb 1977 [1 March 1976] 07151/77 Heading G4R The identity of a person is verified from an electrical signal representing a reference utterance by (1) sampling the electrical signal, (2) computing a plurality of moment variants from the samples to form an identifier moment invariant vector, (3) comparing the vector with a plurality of stored imposter moment invariant vectors derived in a similar manner from other people to provide a plurality of weighting factors forming a weighting vector which maximizes the difference between the identifier and imposter vectors. As described i (= 23) moment invariants MI are computed for each person k according to the formula where y i  = value of the sampled signal at time x i , N = number of samples and p+q#6 (p, q integers). For a plurality n of utterances by the same individual k, average moment invariants for  are calculated and the difference E kj  between each reference vector and the average computed i.e.  where for The difference E hr  between each stored vector belonging to a particular class r (r = 1 .... m) of people and the average is also computed, i.e. where C ik  is the weight for the ith component of the vector so that the C ik  coefficients form the weight vector for person k and are selected to minimize E kj  and maximize E hr . This is effected by using a separation function:- where and a ih  and a ik  are standard deviations of A ijk , B trh . The value S ik  = 0 is selected if B ih  is less than A ik . An error threshold level T 1k  for the person k is computed such that the probability of an error resulting from the rejection of a correct hypothesis is equal to the probability of an error resulting from the acceptance of an incorrect hypothesis. From this a second threshold T 2k  is derived by multiplying T 1k  by a selected ratio factor. In a bank customer verification system, the computed data items relating to a customer (i.e., the moment invar iant vector, weight vector and threshold level T 1k ) are recorded on for example a magnetic credit card. When used, from the reference utterance of the person the coefficients of the moment invariant vector MI i  are computed and using the moment invariant vector and the weight vector recorded on the card an error value is computed and compared with the threshold T 2k  derived from the recorded threshold T 1k  to verify the user.

Title: Improvements in hydrogenation of monosaccharides
Filed: 1953-03-16
Abstract: <PICT:0740560/IV(a)/1> Non-gelling, non-crystallizing high-viscosity polyol compositions are made by introducing a monosaccharide and an alkali metal or an alkaline earth metal hydroxide into water to form a mixture containing from 40 to 70 per cent by weight of monosaccharide and from 0.15 to 0.4 hydroxyl equivalents of hydroxide per litre; heating the resulting mixture to 40-80 DEG , preferably 50-65 DEG  C.; maintaining the mixture at the said temperature for a time corresponding to a time-temperature point within the polygon ABCDE; adjusting the pH of the resulting solution to a value of from 7 to 5.0, preferably 7-6; and hydrogenating the resulting solution in the presence of a hydrogenation catalyst, at a temperature of 120-170 DEG  C., preferably 140-160 DEG  C., and a hydrogen pressure above 500, preferably 1500-2000, pounds per square inch.  Glucose, invert sugar, fructose, mannose and xylose are specified saccharides, glucose and invert sugar being preferred.  Readily crystallizable products such as mannitol may be removed and the composition mainly comprising sorbitol is obtained non-gelling and non-crystallizing by limitation of the quantity of sorbitol in the syrup (determined by means of a pyridine-sorbitol complex) so that its pyridine number is not substantially above 60, such limitation being effected by working within the conditions of the polygon.  Neutralization before hydrogenation may be effected by means of acids or by ion-exchange materials.  Reduced supported nickel hydrogenation catalysts are preferred.  Hydrogenation may be effected as in Specification 721,260.  Calcium hydroxide is the preferred hydroxide and preferably not over 0.3 hydroxyl equivalents are used per litre. With invert sugar limits imposed by ABCGF are preferred and with glucose those set by AHCDE.  Particularly preferred for invert sugar are temperatures of 60-65 DEG  C. for about 6 hours and for glucose 50-55 DEG  C. for about 16 hours.  Examples illustrate the conversion of glucose and invert sugar into humectant polyol syrups, alkali treatment being with sodium, barium or calcium hydroxides, any mannitol obtained in the processes being removed after crystallization.

Title: Improved trench digging apparatus
IPC: E02F3/30
Filed: 1949-03-22
Abstract: 657,733. Scoop arm excavators. HAMILTON & CO., Ltd., C. W. F. March 22, 1949, No. 7774. Convention date, March 25, 1948. [Class 68 (i)] A scoop arm excavator particularly adapted for trench digging as the scoop arm 4 during the digging stroke is constrained to follow the course of the trench, but on the return stroke is deflected sideways from the course of said trench so that the excavated earth is dumped clear thereof. The scoop arm 4 is universally mounted in a head 2b secured to a yoke 2 surrounding the front of the tractor vehicle. The yoke is adjustable about the pivoted attachment to the vehicle, and at the rear carries a weight to counterbalance the scoop assembly. On the head is a guide plate having a slot 12 therein, the slot being in alignment with the course of the trench, and during the digging stroke a tapered roller 11 on a bolt, axially mounted in the end of the scoop arm, projects therethrough so constraining the arm to follow the course of the trench. Towards the end of the digging stroke, the roller clears the slot in the guide plate and its re-entry is prevented by a V-shaped pivoted plate 13, the roller lifts up and then drops behind it on leaving the slot. On the return stroke, this plate deflects the roller to one side of the guide plate which is formed as an arcuate guide so that the arm is deflected sideways clear of the course of the trench and returns to said course at the end of the return stroke when the roller again enters the slot. To which side of the trench the arm moves is determined by an adjustable plunger acting on the arm to bias it to one side or the other. The scoop is pivotally mounted at the end of the arm, it being held in position during the digging stroke by an abutment 25 on the arm 4. At the end of the digging stroke, a chain 31 and rod 32 cause the scoop to rotate slightly about the pivots 9 so ensuring that the excavated earth is well within the scoop and at the same time the arm 24 with an abutment 28 is pulled clear of and below the abutment 25, and on the return stroke the opposite faces of the abutments 25, 28 engage, so locking the scoop in a dumping position during the sideways travel from the course of the trench. Towards the end of the return stroke, the weight of the scoop causes the abutment 28 to disengage the underside of abutment 24 and return the scoop to the original position ready for the next digging stroke.

Abstract: 1,196,531. Gate for foundry sand hopper. M. W. HARTMANN MFG. CO. Inc. 19 Feb., 1968, No. 8015/68. Heading B8S. [Also in Division F1] At the bottom of a foundry sand hopper (not shown) gate body 11 is fixed on which is mounted gates 23 and 24 pivoted at 19 and 20 and interacting by gears 39, 41. The gates are operated by air cylinder 47 of which the piston 48 and cylinder casing are secured to the respective gates at 53 and 54. Control of gates 23, 24 (Fig. 2).-This is effected by the engagement of boss 77 fixed on gate 23 with knob 76 of valve 70 in the pneumatic circuit. The operator pulls cord 84 to cause air to enter cylinder 47 to pivotally open the gates 23, 24. At the end of the opening movement, boss 77 engages knob 76 to cause reversal of the movement of the cylinder so that the gates now close, whereupon the action of opening and closing repeats itself. the movement being rapid so as to facilitate the discharge of the material from the hopper. Pneumatic circuit (Fig. 5).-The action is started by the operator pulling the cord 84 to operate valve 80. This allows air from 81 to operate valve 60 to cause cylinder 49 to open the gates 23, 24. Gate 23 moves rightwards and engages knob 76 to close valve 70 and permit air via line 69 to operate valve 60 to cause cylinder 49 to close the gates. This repeats.
