Title: Fifo replacement data storage
IPC: G11C7/00
Filed: 1977-06-13
Abstract: 1533831 FIFO storage INTERNATIONAL BUSINESS MACHINES CORP 13 June 1977 [2 July 1976] 24608/77 Heading G4A Each storage area 0-7 has a marker bit a-h, an encoding (EXOR) circuit 10 produces from the marker bits an indication of which storage area was the first to be loaded, and each time a storage area is loaded its marker bit is inverted, whereby the encoding circuit identifies the storage areas in a predetermined cyclic sequence. The encoding circuit shown produces coded bit combinations ABC in Gray code sequence when the marker bits are set from 0 to 1 in the order a, b, d, c, g, h, f, e and are subsequently reset from 1 to 0 in the same order as successive storage areas are loaded (overwriting occurring after the first sequence). The FIFO store may form the cache memory of a multilevel storage system, the output of circuit 10 being decoded to select the storage area to receive replacement data from main storage when the requested data is not present in the cache.

Abstract: 1,110,783. Radio signalling; transistor pulseclipping circuits. E.M.I. COSSOR ELECTRONICS Ltd. 14 June, 1965 [13 June, 1964; 20 April, 1965], Nos. 24632/64 and 16674/65. Headings H3T and H4L. In an apparatus for determining the optimum carrier frequency for use in a radio transmission system, of the type disclosed in Specification 1,110,784 wherein a sequence of pulses of oscillations of differing frequency is sent from the transmitting end, receiving apparatus comprises means for detecting whether the ratio of the received pulse amplitude to the average signal level over a predetermined period exceeds or does not exceed a given value for the respective pulses in a sequence. This is achieved by the circuit of Fig. 5, the demodulated pulses being supplied to the junction of resistors 60, 64. Each pulse 48 has a duration of 50 to 250 Á. sees. and is allotted a 10 m. sees. interval during which it will be received, the 10 m. secs. intervals being spaced by 5 m. sees. intervals, Fig. 3 (not shown). At the beginning of each 10 m. sees. interval short pulses 44 discharge capacitors 61, 67 via transistors 62, 68 respectively and during the 10 m. sees. interval the incoming signal (including noise) is averaged by circuit 60, 61 and supplied to one terminal of a twostate circuit 69. A portion of the incoming signal as determined by potentiometer 65 is peak rectified by circuit 66, 67 and supplied to the other input terminal of circuit 69 so that circuit 69 will be in one state or the other in accordance with which of the input signals is the greater. The amplitude of the received pulses is also quantized and supplied to a display means, Fig. 4 (not shown), and the output of device 69 supplies an " inhibit " signal to block the display if the voltage across capacitor 61 is greater than that across capacitor 67. The " inhibit " signal is supplied via gate 70 controlled by pulses 42 at the end of the 10 m. seoa. interval.

Title: Improvements in the manufacture and production of hydroxy ketones
IPC: C07C49/17
Filed: 1931-09-05
Abstract: Methylol-ketones are manufactured from open chain aliphatic or cycloaliphatic ketones and formaldehyde or agents supplying formaldehyde, such as paraformaldehyde and trioxymethylene, by warming the said initial materials in a neutral aqueous or aqueous-alcoholic medium in the absence of condensing agents.  The reaction may be carried out at 50-200 DEG  C., preferably at about 100-150 DEG  C., and preferably in closed, pressure-tight vessels. In order to ensure the complete consumption of the aldehyde, excess of ketone, e.g. two molecular proportions or more, may be employed. In examples: (1) acetone and aqueous formaldehyde are heated to 100 DEG  C. in a low pressure vessel to produce unsymmetrical dimethylolacetone; (2) methylethyl ketone and aqueous formaldehyde are heated in an autoclave to 120 DEG  C. yielding dimethylol-methylethyl ketone; (3) acetone is heated with trioxymethylene and aqueous formaldehyde in an autoclave to 120 DEG C., producing dimethylol-acetone; (4) cyclohexanone and aqueous formaldehyde are heated in an autoclave to 120 DEG  C. to produce a compound of the probable formula <FORM:0381686/IV/1> (5) acetone is heated with trioxymethylene, aqueous formaldehyde and ethyl alcohol in an autoclave to 120 DEG  C. yielding dimethylolacetone.

Abstract: 1435003 Closure fitting T D WILLIAMSON Inc 24 May 1973 [5 June 1972] 24991/73 Heading F2P A closure fitting comprises a conduit member into which a plug is insertable to provide a fluid tight closure of the conduit, and means for releasably locking such an inserted plug in the conduit member. A plug 27, (Fig. 2) removably attached to the boring bar 28 of a hot tapping machine by a plug holder 29, held in place by a retainer rod 30, has an opening 31 and check valve 32 which when open permits the equalization of pressures across the plug. Said valve may be held open by a push rod 33. The plug is provided with an 0-ring type seal 34 and when suitably positioned, can be locked in place in the conduit member 35 by locking means engageable with a groove 38 in said plug. The locking means comprises at least one arcuate locking element 36 and an associated connector 39, disposed in the small diameter section 40b of a bore 40, said connector being provided with a threaded end for connection with a nut 41 which is situated in the large diameter section 40a of bore 40. A threaded bushing 43 is insertable into the bore 40 and a wrench 44 is insertable through said bushing for engagement with said nut. Upon rotation of the nut 41 by the wrench 44, the nut abuts either the inner face of the bushing 43 or the shoulder 42 formed by the charge in diameter of the bore 40, further rotation of the nut resulting in movement of the connector 39 which is provided with a bifucated end for connection to the locking element 36 by use of a pin 39b. Thus the locking element 36 may be retracted from or extended into engagement with the plug 27 according to the direction of rotation of the nut 41. After use, the wrench 44 may be removed and a plug 47 may be inserted. An "O"-ring 46 provides a seal between the connector 39 and bore 40b.
