Title: Differential pulse code modulation transmission system
Inventor: PETERS JOSEPH HUBERTUS
IPC: H04N19/593
Filed: 1983-10-10
Granted: 1986-04-10
Abstract: Differential pulse code modulation transmission system comprising a transmitter and a receiver. In the transmitter there is subtracted from an information signal x(n) to be transmitted, a prediction signal y(n) for the purpose of generating a difference signal e(n), which is quantized and converted into a quantized difference signal in a quantizing arrangement 6. This difference signal is applied to a prediction circuit 7 for generating the prediction signal. It is also transmitted to the associated receiver. In that receiver a similar prediction signal is generated by means of a similar prediction circuit, which prediction signal is now added to the received quantized difference signal. In order to limit the influence of transmission errors in this transmission system, without an excessive increase in equipment, the quantized difference signal is applied in the transmitter and in the receiver to a cascade arrangement of a non-linear network 16 and an auxiliary prediction circuit 17, which produces an auxiliary prediction signal. Before the quantized difference signal is applied to the prediction circuit, the auxiliary prediction signal is first added thereto.

Abstract: An improved method for the preparation of prostaglandin analogs which comprises preparation of two equivalents of an alkyl or alkenyl lithium reagent in an aprotic solvent mixture such as pentane or hexane and tetrahydrofuran, conversion of said reagent by addition of 1 equivalent of copper (I) cyanide to a copper reagent, conversion of said copper reagent to the blocked prostaglandin analog by the addition of a 2-alkylcyclopent-2-en-1-one reagent and quenching of the resultant reaction mixture with aprotic media or an active acylating agent and finally optionally deblocking the resultant product is disclosed. This method is an improvement over previous methods in that more modest temperatures and less hazardous and/or less complex reagents are used and in that for some analogs the method is shorter than previous methods.

Abstract: A system employing a method that detects the occurrence of keywords in continuously-spoken speech evaluates both the keyword hypothesis, and the alternative hypothesis that the observed speech is not a keyword. A general language model is used to evaluate the latter hypothesis. Arbitrary utterances of the language, according to this model, are approximated by concatenations of a set of filler templates. The system allows for automatic detection of the occurrence of keywords in unrestricted natural speech. The system can be trained by a particular speaker, or can function independently of the speaker.

Abstract: (57) A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided. The stapling instrument incorporates a staple height adjusting mechanism which enables the gap between its jaw members to be adjusted to select different staple heights to be produced when the staples are formed. Preferably, the stapling instrument includes a pair of elongate jaw members, one of which supports a staple cartridge adapted to receive at least two laterally spaced longitudinal rows of staples, and the other provided with an anvil adapted to form the staples. A pusher bar and knife assembly slidable longitudinally relative to the jaw members sequentially drives the staples from the cartridge and forms the staples against the anvil to produce a pair of laterally spaced rows in the tissue. The pusher bar and knife assembly includes a knife blade for cutting the tissue along a line between the longitudinal staple rows. A set of jaw support members is carried by the knife blade which travel along the elongate jaw members as the pusher bar and knife assembly is advanced to provide local support to the jaw members. The angular orientation of the knife blade relative to the jaw members is adjustable by the staple height adjusting mechanism to vary the vertical spacing between the jaw support members as the gap between the jaw members is varied.

Abstract: Sulfates of glutathione monoalkyl esters ( alkyl y -L-giutamyl-L-cysteinylglycinates ) are new and can be prepared by reaction of glutathione with an alcohol in the presence of sulfuric acid. This process forms virtually no diesters, which are toxic compounds and must be completely removed when the sulfates are used as medicine. In addition, since pure glutathione monoester sulfates can be isolated from reaction mixture, high-purity free glutathione monoesters, which have importance as therapeutical and preventive medicines, can be obtained by treatment with a neutralizer or by mere desalting.

Abstract: The gear drive or transmission comprises toothed elements whose radial spacing from a drive shaft can be selectively altered. There are two sets of such toothed elements whose aforementioned radial spacing can be infinitely varied in increments or sets. Each set of the toothed elements has operatively associated therewith at least one planetary gear which always meshes with one of the toothed elements of the associated set. The drive shaft generates, on the one hand, between the toothed elements and each of its associated planetary gear, on the other hand, a relative revolving or orbiting motion. Coacting with each planetary gear is an intermediate gear train which is positively or form-lockingly connected with one of the freely rotatably mounted starting elements of a differential gearing. A compensation element of the differential gearing is rotatably mounted at the end of a radially protruding arm rigidly connected for non-relative rotational movement with the drive shaft. The autorotation and the revolving or orbiting motion of this compensation element is transmitted by a gear train to a power take-off shaft. Since the toothed elements and thus the planetary gears are infinitely radially adjustable there also is altered the circumferential velocity at their point of engagement, so that there results the infinite variability of the transmission or gear ratio.
