Title: Pressure Pipe for Encapsulated Refrigerating Machines.
IPC: F25B31/02
Filed: 1968-01-01
Abstract: 1,175,161. Resilient vibration isolators. DANFOSS A.S. 1 Jan., 1968 [19 Jan., 1967], No.47/68. Heading F2S. In a refrigerator a pipe which conveys refrigerant to a compressor can itself serve as a resilient vibration isolator for the compressor. The invention provides a pipe for such use which is so constructed as to have portions of different natural frequency. There are required to be at least three such portions, the natural frequencies of which differ from each other by one third of an octave. In the example shown each of the portions 1, 2, 3, 4, 5 and 6 is one " wavelength " of a sinuous undulation whose amplitude diminishes by 40% from one portion to the next. There is a straight pipe length between portions 4 and 5 and another, 8, at one end of the pipe.

Abstract: A beet-harvester comprises a pair of inclined elongated lifting elements rotatable side-by-side in opposite directions, each element having a tapered lower end-portion and having a first helical winding extending externally along the entire length of the element, and a second helical winding extending only along the tapered end-portion between adjacent turns of the first helical winding.  Above the elements is an endless conveyer with pendant rubber pusher-plates which travel up the elements at the same rate as the beets are fed thereby and prevent their slipping back, fixed guards being mounted at each side of the elements to prevent lateral escape of the roots. Each element is mounted on a shaft carried on upper and lower bearings the lower shaft-bearing lying inside the element adjacent to the tapered end-portion which is separated from the body of the element by a slit, through which passes a bracket supporting the bearing.  Several pairs of elements are mounted side by side and are driven from the towing tractor.

Title: Facsimile synchronizing signal generator
IPC: H04N1/36
Filed: 1948-01-02
Abstract: 666,485. Electric synchronous movements. TRIGGS, W. W. (Faximile, Inc.). Jan. 2, 1948, No. 148/48. Class 40 (iii). [Also in Group XL (c)] A facsimile synchronizing signal generator comprising a source of periodic synchronizing signals, a switching device for passing predetermined ones of said signals to a utilization device, and an element for conditioning said switching device to pass said predetermined signals, is characterized in that a storage element is connected between said switching device and said conditioning element in order to mask irregularities in the operation of the latter. A synchronizing segment 11 (Fig. 2), driven by the shaft of a facsimile transmitter applies positive bias over a timing circuit 15, 16, to the control electrode 9 of a thyratron 5. The next pulse from a square-wave generator 22 therefore fires the thyratron 5 and produces a square output pulse for synchronization purposes. The timing circuit 15, 16 maintains the control electrode at a sufficient potential even in the presence of poor rotary switch contact, so that the thyratron will still fire when the next generator pulse arrives. In a second embodiment (Fig. 4) the synchronizing segment 11 removes negative bias from a thyratron 26 to allow the next square-wave from a generator 30 to pass and so condition a second thyratron 37 to conduct when it receives a square-wave from a second generator 44. The square-waves from the second generator 44 arrive slightly later in time than those of the first generator 30. Synchronizing pulses are taken from the cathode resistor 43.

Title: Method and system for sorting without comparator

Filed: 1972-01-04
Abstract: 1383991 Data sorting system DIRKS COMPUTER SYSTEMS CORP 4 Jan 1972 [7 Jan 1971] 329/72 Heading G4M  A data sorting system successively stores data  in one of two predetermined areas depending on the value of predetermined bits. A sequence of data words each containing an identifying key field and a record unit address is fed to a processing register and then to a holding register 11. A multiplexer enables successive examination of the least significant bit of each key field and the key field and address are fed to an address register A and stored in a location depending on whether the bit is " 0 " or "1". Before entry of the key fields a " 0 " address counter  and a " 1 " address counter in each of register  A, B are set to all zeros and all "1"s respectively. Each time a key word is fed to the appropriate register the " 0" counter is incre-  mented or the " 1 " counter is decremented and used to store the keyword and address in the appropriate location. This continues until the two counters have the same value when a comparator (Fig. 5, not shown) causes transfer of the stored key fields and addresses to register B.  The words are fed via the multiplexer to control register B as described above, however, the words are allocated according to the value of the  next to the least significant bit of the key field and the " 0 " address counter is set to all zeros and incremented successively to transfer all the words from the "0" bit section. When the  " 0 " counter has the same value as the " 1 " counter the latter is set to all " 1 "s and decremented for each word transferred. When the two counters have equal values the transfer is complete: The process is continued under the control of successively more significant bits of the keyfield with the " 0 " section of the register being the first section read during .transfer.  When all keyfield bits are read the words are in  numerical order of the keyfields and the whole data held in the record unit addresses may be accessed. Preferably the data is held in circulating stores and the bits may be interlaced or the  words may be consecutive.
