Title: Improvements in or relating to the production of knotted pile fabrics
IPC: D04G3/00
Filed: 1966-09-07
Abstract: 1,129,914. Hand-made carpets. PANGAFIN SOC. ANON. HOLDING. 7 Sept., 1966 [10 Sept., 1965], No. 40013/66. Heading D1K. Pile fabric having knots as shown in Fig. 5 is made by first preparing strips of pile tufts 8, Fig. 11, the ends of the tufts being attached to adhesive bands 10, 13. The tufts 8 are assembled from differently coloured yarns as required for the pattern; alternatively, each strip of tufts may contain yarns of only one colour, gaps being left where other colours occur in the pattern, a full row of tufts then being obtained by superimposing, several strips. The strips can be cut from long lengths of yarns having adhesive bands applied at intervals. To knot the pile into an open mesh canvas, a pile strip is folded in two and hung on hooks 32, Fig; 20. The canvas is then imparted on the shanks 33 of a row of grippers 34. Next, the hook assembly 31, 32 is taken off its support 75 and swung downwards to bring the pile tufts 8 into the grippers 34, Fig. 21. After closing the grippers on to the tufts, the hook assembly 31, 32 is disengaged from the tufts and replaced on its support 75. Finally, the loops of the tufts 8 are stripped off the shanks 33 together with the canvas, thereby forming the tufts into knots.

Title: Centrifugal pump with canned motor
IPC: F04D1/06
Filed: 1959-11-26
Abstract: 925,881. Bearings; lubricating. H. KRAEMER. Nov. 26, 1959, No. 40127/59. Classes 12 (1) and 12 (3). [Also in Groups XXVI and XXXV] A centrifugal pump is driven by an electric motor of the type in which the rotor is enclosed in a jacket 12 and the stator is shielded by a cylindrical liner 10. Liquid from the highpressure end of the pump enters the motor through passages 8 to cool the motor and lubricate the bearings. The liquid enters each bearing through the gap between the flanges 21 and 23 of stationary and rotary parts 17, 19 of the bearing and flows through longitudinal grooves 27 provided in either the stationary part 17 or the rotary part 19. On leaving the left-hand bearing, the liquid passes through holes 26 into the low-pressure side of the last stage of the pump, while the liquid leaving the right-hand bearing passes through the hollow shaft to the pump inlet 2. End movement of the shaft due to the thrust exerted by the pump increases the gap between one pair of bearing flanges 21, 23 and decreases the gap between the other pair, the resulting variations in the resistance to flow through the bearing causing a corresponding decrease in the fluid pressure in chamber 16 and a corresponding increase in the fluid pressure in chamber 9. The resultant differential end thrust on the motor rotor balances the end thrust of the pump. The diameter of the flanges 21, 23 of one bearing may differ from that of the other bearing or may be adjustable, as by means of removable rings. The cross-sectional area of the grooves 25 of one bearing may be different from that of the other bearing or may be adjustable, as by the use of inserts.

Title: Phase-locked loop
IPC: B62D33/06
Filed: 1974-09-20
Abstract: 1480581 Automatic phase control ROBERT BOSCH GmbH 20 Sept 1974 [22 Sept 1973] 41029/74 Heading H3A A phase locked loop for multiplying the frequency of an input signal f E  comprises: a digital frequency multiplier 17 having a multiplication factor which may be less than unity; an up/ down counter 15 controlling the multiplication factor of multiplier 17; and a second counter 16 fed with the output from the multiplier, and producing an output which adjusts the stored value in the counter 15 in dependence on the contents of the counter 16 at the beginning of an excusion of the input signal. The output signal f A  is produced by multiplying the frequency of a clock signal f O  in multiplier 17 by a factor determined by the count in counter 15, and the input signal f E  is sampled, in sampler 10, by the clock signal f O  to provide periodic pulses which set counter 16 to an initial count determined by memory 19. The sampler 10 output is also applied to one input of a NAND gate 14. The output pulses from multiplier 17 cause counter 16 to count down, and if the frequencies are correct, this counter arrives at a count of "1" at the time of arrival of the next pulse from sampler 10. With the counter 16 in this state logic circuit 20 provides an inhibit pulse at NAND 14. The multiplication factor is set by the value stored in memory 19. If the frequency of the input f E  increases, counter 16 will not have counted down to "1" before the arrival of the next pulse from sampler 10, logic circuit 20 will provide an enable signal to NAND gate 14 and will also provide, at the output of OR gate 23, a signal which instructs counter 15 to "count up". The pulse from sampler 10 is thus passed through NAND gate 14 to increase the count in 15 and hence increase the multiplication factor of multiplier 17. If the frequency of input signal f E  decreases, counter 16 will count down to zero before the arrival of the next pulse from sampler 10. In this case, logic circuit 20 again enables NAND gate 14 but the output from OR gate 23 instructs the counter 15 to count down, so that the count and hence the multiplication factor are decreased. A modification, Fig. 2 (not shown), includes a further counter (101) and will apply several correction pulses to counter 15 instead of single ones.
