Title: Apparatus for generating output selection signals associated with each of a plurality of information data records
IPC: G03G15/00
Filed: 1974-10-22
Abstract: 1492065 Card reader XEROX CORP 22 Oct 1974 [25 Oct 1973] 45571/74 Heading G4M Data from cards is selected for processing, e.g. electrophotographic printing under the control of data read into a memory from a set of three program cards. For each program sequence the three program cards are a control card, a care/don't care card and a mark/no mark card. Data read from each card is fed to the corresponding memory configuration of control memory and decision means 8 and the channel mark/care memories and compare means 3-7. The first card presented is the control card which determines whether an AND/OR decision is required, whether to print or strip data and which of two counters 9, 10 is to be used. The second card carries data indicating whether each of the 16 bits in each of 5 columns (A to E) of the data cards is to be compared or not compared with preselected data. The third card defines the value of the bits used for the comparison. When all the program cards have been read and stored a program/read flip-flop is reset to establish a read mode and the data cards are read using the same reader, and the data from each card is compared with the stored data from the first program card. The leading edge of a card fed into the reader is detected to produce a pulse for a threshold setting interval. Lead control networks associated with a clock track and the five data channels establish a threshold level which depends on ambient light level and on the nature of the cards. Data on the cards is situated between clock pulses on the pulse track so a clock pulse is first detected to enable feed of a marker bit to a shift register. The first bit in each data channel is read and fed into channel format conversion networks. When all the 16 bits of data have been read and the 17th clock pulse has been detected the marker bit from the shift register enters a counter to prevent further shifting of data in the stages of the conversion networks. Data is then fed via a multiplexer to the read/write memory address and selection control network 2 which supplies data from channels A to E to the mark/care memories and compare means 3-7. If an incorrect number of clock pulses is received a start memory cycle pulse is not produced. The data is compared with the stored mark/ no mark data using Exclusive OR gates (Fig. 4, not shown) and the result fed to gates controlled by the AND/OR control data. Data from these gates is fed to gates controlled by the stored care/don't care data to produce a select decision output. The data may be carried by data cards or microfiche which may be sorted.

In a process for the production of fresh water from salt water wherein part of the salt water is frozen by contact with a liquid refrigerant, e.g. butene-1 or iso-butene, to form ice crystals, the unfrozen salt water is removed by centrifuging to leave the ice crystals each covered by a salt water film, the crystals are contacted by the vapour of the refrigerant to form, by melting, a thin film of water between the crystal and the salt water film, and the resultant crystals are centrifuged to separate the residual salt water therefrom. Following contact with the refrigerant vapour, the crystals comprise superimposed layers of fresh water, salt water, and liquid refrigerant, the final centrifuging removing these layers except for part of the fresh water. Batch or continuous processing may be used, and the centrifuge separating forces should preferably be in the range 50 g. to 150 g. Specification 954,926 is referred to.

Abstract: 1485217 Reducing NO x  in exhaust gases MITSUBISHI CHEMICAL INDUSTRIES Ltd 4 Nov 1975 [9 Nov 1974] 45818/75 Heading C1A [Also in Division F4] Nitrogen oxides are removed from an oxygencontaining exhaust combustion gas from a furnace burner by intercepting the combustion flame with a flame interceptor, and supplying an ammonia source to a zone at more than 700‹ C. downstream of the interceptor so as to contact ammonia with the combustion gas. The ammonia source may be NH 3  or a precursor that generates NH 3  under the reaction conditions.

The ammonia source may be diluted with inert gas, air, steam or exhaust combustion gas before supply to the reaction zone. The ammonia source may be cooled, to avoid premature decomposition, by using a jacketed feed pipe. Examples describe the operation of a combustion furnace in which the flame contacts and is intercepted by a perforated porcelain plate, providing a flame-free zone at 900‹ C. into which NH 3  or NH 3  plus H 2  is injected, optionally through a plurality of nozzles.

Title: A process for the production of glutamic acid
IPC: C12P13/14
Filed: 1961-12-27
Abstract: L-glutamic acid is produced by adding to a culture medium containing a carbon source, a nitrogen source and one or more inorganic salts, such a number of cells of an L-gluatamic acid producing microorganism, to give a concentration at least equal to the concentration at the "stationary phase", i.e. that concentration at which the rate of propagation of new living organisms is balanced by their death in that medium, culturing under aerobic conditions and recovering the accumulated L-glutamic acid from the cultured medium.

Filed: 1966-10-18
Abstract: 1,196,405. Resilient mountings. D. V. WATKINS. 17 Oct., 1967 [18 Oct., 1966], No. 46621/66. Heading F2S. A vibration isolating mount, for apparatus such as a check weigher required to be protected from low frequency vibrations of a supporting foundation such as a factory floor, employs springs of the form shown in Fig. 2. A coil spring 1 when "crippled" into C-shape and stressed by a force tending to further distort the C-shape has virtually zero stiffness and therefore can serve as a resonator with very low (1 c/s) natural frequency. This is the basis for its use as a suppressor of low frequency (down to about 5 c/s) vibrations. The invention provides a vibration isolating system in which (Figs. 3 to 5, not shown) a plurality of such crippled springs are each fitted with knife edges 4 which engage V-blocks 6 mounted on supporting and supported members, lateral displacement of the supported member being restrained by resiliently mounted tie-rods (18). The system can be tuned by adjusting the position of the knife edges on the straight terminal portions 3 of the springs. The knife edges may alternatively be on the supported and supporting members and the V-blocks on the springs.
