Title: Aparelho de testes para vela.
Inventor: SOUZA MILTON MIGUEL RODRIGUES
IPC: H01T13/58
Filed: 1997-11-27
Abstract: "APARELHOS DE TESTES PARA VELA", refere-se a presente adição da invenção do aparelho de testes para velas resistivas aplicado no sistema elétrico mecânico de ignição de motores a explosão. O eletrodo central de ignição da vela resistiva é cortado em duas partes e emendado ou colado novamente com uma massa resistiva especial condutora de eletricidade. Esta resistência é programada para alcançar cerca de 6K olhms, porém a massa fora das especificações ou mesmo a soldagem das partes interrompidas mal feitas irá ocasionar uma resistência muito maior que a desejada criando interrupções na centelha da corrente elétrica, produzindo falhas no motor, um consumo maior de combustível e um motor não confiável. Os testes que existem no mercado são muito complicados, caros de difícil interpretação e alguns casos não confiável, porquê passar uma corrente de alta intensidade por uma vela tais como: 15, 20, 30 mil voltz, a corrente pulará vez ou outra dificultando sua análise. No caso de velas novas não temos como testar com confiança a rapidez a não ser por esse processo desenvolvido desde uma corrente de baixa intensidade pelo eletrodo de ignição e chegando as lâmpadas leds testes acendendo e piscando as mesmas. O circuito recebe 110/220 voltz (1) e passa pelo interruptor (2) penetrando no transformador (3) que libera 9,30 voltz que recebe um regulador de voltagem 7808 cv (4) e libera 7,5 voltz que vai até a lâmpada piloto (6) antes recebe na parte positiva uma resistência de 3K olhms (5). Da parte negativa sai um fio que vai ligar a parte negativa da lâmpada led pisca-pisca teste (6), da parte positiva das lâmpadas leds testes sai um fio que vai ligado na parte metálica do suporte de acoplamento da cabeça da vela (8) antes porém recebe um capacitor de 100 10 voltz, e resistências conforme o necessário ponto de equilíbrio. Do fio (11) corrente positiva sai um fio que terá a ponta teste, que encostada no eletrodo de ignição (13) da vela fechará o circuito acendendo as lâmpadas testes e piscando.

Abstract: The invention relates to a hand-held firearm comprising a muzzle silencer (9) and a barrel (11) which is provided with transverse bores and is surrounded by an expansion area (15) into which the transverse bores extend. The transverse bores (14) enable the muzzle velocity of the bullets to be less than Mach 1, in spite of the use of conventional ammunition, and there is consequently no supersonic boom of the bullet. To selectively eliminate the reduction in firing energy involved therein and be able to shoot with maximum firing force, the transverse bores (14) are selectively closable by a locking device (16) which is preferably in the form of a sleeve (16) which surrounds the barrel (11) and is mounted for rotation thereon and is furthermore provided with an actuating member (21) for setting the open or closed position. The actuating member may take the form of a tube section (21) surrounding the barrel (11) in spaced relationship thereto at least over part of its length and delimiting the expansion area (15), with its both ends connected with the barrel in sealed relationship and mounted on the barrel (11) for rotation. The tube section is connected with the sleeve (16) for rotation therewith (FIG. 2).

Title: Producing sand cores - with gas for hardening the binder fed to moulding box as liq. and vaporised inside box
Inventor: BLACHOWSKI HERMANN
IPC: B22C9/12
Filed: 1993-06-01
Granted: 1994-05-19
Abstract: A predetermined volume of hardening liq. is fed to the moulding box or to a component of the box and vaporised by a heating device inside the box. The gas then flows through the moulding sand and hardens the binder. Reaction-free pressurised air is then blown through the box to remove any excess hardening gas. The hardening liquid is metered through a feeding channel (9,10) to the gassing plate (3). As it flows to the opening (14) which connects with the core box (2) it is heated and evaporated by electrical heating units (12,13). After hardening pressurised air is blown in via opening (16). The passage (11) travelled by the gas is zigzag and has vaporising ribs etc., to increase the vaporising efficiency. USE/ADVANTAGE - Producing sand cores. By vaporising the hardening liquid just prior to blowing through the core box, gas is not lost by condensation during transportation. Also the amt. of cleaning air required is reduced leading to cost savings.

Title: Fossil fuel power station process
IPC: F02C3/34
Filed: 1994-03-08
Granted: 1995-06-08
Abstract: In a process to convert fossil fuel into work, fossil fuel is burned to directly surrender heat energy to a process. In this process the fossil fuel is burned with oxygen in the presence of carbon monoxide returned from the combustion output to produce a gas mixture of between 800 and 1500  deg C which drives a gas turbine. The pressure differential between the combustion chamber and the carbon dioxide recovery stage is achieved by condensation on the one hand, and evaporation of the returned carbon dioxide and pre-heating of the combustion chamber, by an internal process of compression to at least 7.2 MPa and expansion undertaken by means of a powerful gas turbo-charger. The novelty is that the recirculated carbon dioxide is liquefied and that the products from the combustion gases are completely removed to the surrounding, while the liquefied carbon dioxide, pressurised to around 40 MPa, is used for recuperative cooling of the working agent after the gas turbine and the compressor, during the course of which it evaporates and is pre-heated.

Title: Method and testing device for determining the minimum rock stress
Inventor: FASKE BERND
IPC: E21B49/00
Filed: 1994-04-12
Granted: 1995-05-11
Abstract: The invention relates to a method and a testing device for determining the minimum rock stress of underground geological formations. Hitherto known methods are relatively costly and time-consuming and require a high investment in equipment. The invention makes it possible reliably to determine and evaluate the stress condition of a geological formation in-situ within a test interval using a further-developed testing device. Testing is performed directly and involves a low outlay on equipment, being carried out by means of on-line depth manometers and the results being evaluated in an above-ground PC station. In the method a significant proportion of the test-gas volume is prepressurised, introduced up to the test interval and compressed there until crack formation occurs. A pressure balance takes place between the foot and the head of the testing device such that axial anchoring of the testing device in the bore hole is not necessary. The fluid which arises in the test interval is passed into a fluid take-up tube which has been used to hold the prepressurized test-gas volume.

Title: electromagnetic transmission system for locating objects
Inventor: SIEBELINK MARCO ROBERT
IPC: G01S5/04
Filed: 1997-01-15
Granted: 1998-07-16
Abstract: The system can be used in place of the conventional electromagnetic passive responder system. It avoids the main disadvantage of the passive system, i.e. the cost and complexity of the field generators and the relatively short detection range. The length of the coded transmission pulse from the signal source is very small compared with the repetition rate. The ratio between pulse length and repetition time is between 0.1 and 0.001. As the transmitter is switched to stand-by between pulses, the drain on the power source between pulses is very small.
