Title: Stylus shielding and unshielding apparatus for a  phonograph
Inventor: FEKETE FERENC
IPC: G11B3/40
Filed: 1984-01-04
Granted: 1985-10-08
Abstract: ABSTRACT          A new and useful phonograph stylus-shielding apparatus and a stylus-unshielding apparatus are provided in combination with a phonograph and recorded-message carrier.  The phonograph includes a housing having a top wall provided with an opening for receiving the recorded-message carrier.  A turntable is rotatably mounted in the housing in alignment with the opening and a tonearm is pivoted to the turntable for rotation thereby.  A reproducing stylus extends upwardly from the tonearm for engaging the recorded-message carrier when it is in position within the opening.  The stylus-shielding apparatus automatically shields the stylus from access through the opening when the recorded-message carrier is removed from the opening and the stylus-unshielding apparatus automatically unshields the stylus when the recorded-message carrier is positioned within the opening.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to the preparation of iyophll-ized, adsorbed polyvalent vaccines.  According to the invention tetanus, diphtheria, pertussis and optionally typhus antigens concentrated to 5 to 15 doses/3 ml are adsorbed at a pH value of 3 to 6 to an insoluble carrier concentrated in the same way as the antigens, then the pH of the mixture is adjusted to a value of 5 to 6 and iyophllized together with a protective material commonly used in iyophllizing processes.  Before administration the iyophllized vaccine is diluted to the concentration required by a physiological saline buffered to a pH value of 6.8 to 7 by a phosphate solution.

Abstract: ABSTRACT:           For processing a signal applied to an input of audio signal processing devices, for example a speech signal received via a microphone (2) in a speaker-identi-fication or speech recognition system, the signal must have a specific level.  For this purpose the signal is applied via an amplifier (4) with variable gain.  Before processing begins the gain is set to an initial value.          During processing of the speech signal it is checked at regular time intervals in which range of a plurality of predetermined amplitude ranges the amplified signal is situated and whether overloading takes place and the fre-quency which the amplitude of the signal occurs in each of the amplitude ranges is counted.  When the signal ends the optimum gain setting is determined from the histogram of frequencies.  In the case of a signal which is specific of an individual speaker and which must be processed in speech recognition or speaker identification systems this optimum gain setting may be stored in a memory (28) at a location assigned to the speaker, and when the system is subsequently used by the same speaker this value is used as the initial setting of the amplifier gain.  In this way the gain is set to an optimum value during the first time that the system is used by a specific speaker and it is corrected continuously when the system is used again by the same speaker.

Abstract: Abstract Two monoclonal antibodies (3-3 and 3-40) were produced which identify two new leukemia associated antigens.  Both antibodies reacted with most cell lines derived from patients with T lymphoblastic leukemia (T-ALL), but were not detected on suspensions of normal hematopoietic cells; including thymocytes, by cytotoxicity, absorption of indirect immunofluorescence assays.  Analysis of fresh leukemic cells indicated that mAb 3-3 only reactd with T-ALL cells, while mAb 3-40 reacted with some non-T non-B          ALL cells and a few acute myelocytic leukemia (AML) cells, as well as T-ALL cells.  The 3-40 antigen was also found histopathologically in frozen sections of several normal tissues, including the epithelial cells and a few lymphoid cells of the thymus, and some malignant tissues, while the 3-3 antigen was not found in any tissue studied.  A "double absorption" assay provided additional serological evidence that the two antibodies identify different antigenic determinants.  Biochemical analysis indicated that the molecules immunoprecipitated by mAb 3-3 and mAb 3-40 have molecular weights of 35-40,000 daltons.  It is demonstrated that the 3-3 and 3-40 antigens are markers for human T-ALL and can be used along with the nonmal T lymphocyte antigen, 3A1, to discriminate T-ALL from cutaneous T-cell lymphoma (CTCL), adult T cell leukemia (ATL) and T cell chronic lymphocytic leukemia (T-CLL).

Abstract: ABSTRACT         A teaching machine is adapted to be used in combination with a card in order to pose a question to a user of the machine and to accommodate both a first case wherein a voice signal is audibly reproduced before the user enters his answer to the question into the machine and a second case wherein a voice signal is audibly reproduced after the user enters his answer into the machine.  The machine includes a signal reproducer adapted to cooperate with a card upon which a control signal, a correct-answer signal encoding a correct answer to the question and a voice signal are recorded and to reproduce the recorded signals from the card.  A user of the machine enters a test answer to the question into the machine via a keyboard.  A first memory responds to the correct-answer signal as reproduced by the signal reproducer for storing the correct answer, and a second memory responds to the keyboard for storing the test answer.  A comparator responds jointly to the first and second memories for making a comparison between the correct answer and the test answer and for producing an output signal in accordance with the comparison.  Lamps are responsive to the comparator output signal for indicating to the user whether the test answer is correct.  An audio channel is jointly responsive to the control signal and the voice signal as reproduced by the signal reproducer for audibly reproducing the voice signal before making the comparison in the first case and after making the comparison in the second case.

The integrated system has a pair of traction winch drums for conveying the wire rope, and a chain wheel for conveying the chain cable. The chain wheel is coaxially mounted with one traction winch drum, and has a wire rope groove with a groove diameter substantially the same as that of the traction winch drums. A sheave positioned directs wire rope between one of the drums and the chain wheel, and is so positioned that a wrap of wire rope is formed about the chain wheel whenever the system is operating on wire rope exclusively. A drive mechanism is provided for rotating the traction winch drums and chain wheel, including a common drive shaft, and a clutch mechanism which permits the traction winch drums and the chain wheel to be located simultaneously or separately. Simultaneous rotation of the chain wheel and traction winch drums is timed so that wire rope is conveyed at the same speed by the traction winch drums and the chain wheel. The chain wheel is effectively integrated into the traction winch functions, the wire rope groove of the chain wheel basically serving as the first groove of a traction winch.

Abstract: ABSTRACT        Chlorine is produced by oxidizing byproduced hydrogen chloride.  An offgas containing hydrogen chloride as a byproduct is reacted with oxygen at 300 -500°C in the presence of a catalyst which contains chromic oxide (Cr2O3) as a principal component.  The resulting gas is cooled rapidly and then washed with water to recover vaporized chromium.  The hydrogen chloride is then absorbed in water to recover it as an aqueous hydrochloric acid solution.  The still remaining portion of the resultant gas is washed with sulfuric acid to remove water from the same, followed by compression and cooling.  The resulting liquefied chlorine is separated.  The still remaining gas composed principally of oxygen is thereafter returned to the oxidation step.
