Title: Alarm pistol
IPC: F41A9/26
Filed: 1932-01-09
Abstract: 376,651. Alarm pistols. WALTHER, G., Larchenberg, Mehlis, Zella, Thuringia, Germany.-(Assignee of Walther, F., Walther, G., and Walther, E., (trading as Walther, C.) ; Larchenberg, Mehlis, Zella, Thuringia, Germany.) Jan. 9, 1932, No. 688. Convention date, Jan. 16, 1931. [Classes 9 (ii) and 119.] An alarm pistol comprises a rotatable drum 5 formed with radial cartridge-receiving chambers 9a, . . d, and mounted on a journal 21 which is so bored as to establish communication between the chamber opposite the nose 8 of the firing hammer 3 and the bore 22 of the barrel 2. A pawl 13 on the sliding trigger 4 is adapted to engage successively with a number of pins 14 on the drum 5 so that the latter is rotated to bring a fresh cartridge opposite the hammer at each pull of the trigger. The cartridges 20 are fed successively into the chambers from a tubular magazine 15 which is screwed into the metal below the barrel 2. The cartridges are urged towards the chambers by a spring-controlled feed member 18 which, when the last cartridge has been delivered, enters one of the chambers and prevents further rotation of the drum. The trigger 4 is spring controlled and is formed with a rib 11 which, by engaging with a pin 10 on the spring-controlled hammer 3, first depresses and then suddenly releases the latter to fire a cartridge. A pivoted spring-controlled ejector lever 24 is struck by a shoulder 23 of the hammer when the hammer is released on firing. A claw 27, Fig. 3, of the ejector lever engages beneath the rim of the spent cartridge in the uppermost chamber 9d, and ejects it. In an alternative construction, a supplementary passage in the journal 21 establishes communication between the chamber opposite the hammer and a chamber containing a spent cartridge case. This construction utilizes the gases of explosion to perform the ejecting operation.

Title: Making synthetic resins
IPC: C08G8/28
Filed: 1941-02-20
Abstract: 547,329. Phenol-aldehyde resins. CHARLTON, W., HARRISON, J. B., WATERS, R. B., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 20, 1941, No. 763. [Class 2 (iii)] Phenolic resins suitable for blending with drying oils, e.g. tung oil, to give varnishes are obtained by heating a methylol derivative of a p-alkyl-substituted monohydric phenol, e.g. pcresol, p-tert-butyl phenol, p-octyl phenol, with an aliphatic aldehyde having 3-8 carbon atoms to 70-160‹C. in the presence of an acidic catalyst with or without further hardening at 160-190‹C. The reaction is carried out by heating in presence of an inert solvent e.g. toluene until the water of reaction is eliminated. The methylol derivative is defined as a phenyl dialcohol obtained in known manner by condensing phenols with two mols. formaldehyde in presence of alkaline condensing agents. Aldehydes specified comprise n-butyraldehyde, iso-butyraldehyde, heptaldehyde, and 2-ethylhexanal excess preferably being used to give a freely flowing product from which impurities, e.g. salts, can be removed by filtration. The resins maybe blended without frothing to give long or short oil systems. Driers, e.g. linoleates or naphthenates of cobalt or lead may be incorporated. In examples (1) ptertiary butyl phenol dialcohol is prepared by reacting the phenol with formaldehyde and caustic soda solution the product being acidified with hydrochloric acid to separate out a heavy oil which is run off and washed. The crude dialcohol is mixed with n-butyraldehyde and syrupy phosphoric acid, allowed to stand until the temperature reaches 40‹C. whereupon the water of reaction is distilled off and the residue heated to 150-160‹C. for four hours. Further heating to 180‹C. for three-quarters of an hour gives a clear hard brittle resin. The resin prior to heating may be mixed with fullers earth and then filtered.

Filed: 1923-01-11
Abstract: 217,259. Shannon, D. S. B. Jan. 11, 1923. Thermionic amplifiers and detectors. - The grid condenser of a rectifying valve is of comparatively large capacity, say from 0.0005 to 0.01 microfarads, and is shunted by a leak of comparatively small resistance, say 100,000 ohms or less. In addition the grid is connected through the leak resistance to the positive terminal of the filament battery. This arrangement is stated to increase the sensitivity of the receiver and to render the use of an elevated aerial unnecessary. As shown in Fig. 3, the grid leak m, instead of being connected directly to the positive terminal of the battery j, is tapped to a potentiometer p. The earth lead c may be taken from the upper or lower ends or from an intermediate point, of the inductance a. Fig. 5 shows the invention applied to a receiving circuit of the superregenerative type. The grid of the quenching oscillator 1 is connected through a switch to the grid of the detector-amplifier d. The positive terminal of the battery 6 is connected to the grid of the oscillator 1 through a lead 5 and the receiving inductance a. An auxiliary battery 4 is inserted in series with the battery g to feed the plate of the oscillating valve.

Title: A method of reducing the influence of fading of a viterbi-receiver having at least two antennas
Inventor: BAECKSTROEM TOMAS OLOF
IPC: H04L25/03
Filed: 1995-03-09
Abstract: Signals in synchronizing sequences and data sequences are transmitted over a fading channel to a Viterbi-receiver (11, 12). The signals are received by antennas and sampled to received antenna signals (sin,r(k)). Part channel estimates (hest,r) for the individual antennas are formed. For Viterbi-analysis, assumed input signals (sa,r( DELTA Tij,k)) for the data sequence are produced with the aid of the part channel estimates (hest,r). Part metric values (mr( DELTA Tij,k)) are formed as a difference between the received antenna signal (s,in,r(k)) and corresponding assumed input signals (sa,r( DELTA  Tij,k)) for Viterbi state transitions ( DELTA Tij). For one state transition there is formed a metric value such as the sum of a metric value ((M(Tj,k-1)) for an old state (Tj) at a preceding sampling time point (k-1) increased with a weighted (Kr) sum of the part metric values (mr( DELTA Tij,k)) belonging to individual part channel estimates (hest,r). Corresponding metric values are formed for all state transitions to the new state (Ti) and the smallest of these metric values is chosen in accordance with the Viterbi-algorithm.

Title: Multichip-type semiconductor device
Inventor: MORI YOSHIHIDE
IPC: H01L25/18
Filed: 1992-01-06
Abstract: PURPOSE:To provide a multichip-type semiconductor device of simple structure which can be manufactured through a smaller number of production processes than the number of conventional processes. CONSTITUTION:The part 21a of an outer lead 21 mounting a power transistor chip 22a is exposed from a semiconductor device 20. When a bump 23 is formed on the bottom face of a control IC chip 22b and directly connected with the outer lead 21, the control IC chip 22b and outer lead 21 are connected electrically. Thus, it is possible to simplify the structure of the semiconductor device, especially the heat-dissipating structure thereof, because heat generated in the power transistor chip is dissipated to the outside via the outer lead. Also, because the control IC chip and outer lead are electrically connected via the bump, a wire bond process for connecting the control IC chip and outer lead becomes useless so that the title multichip-type semiconductor device can be manufactured through a smaller number of production processes than the number of conventional processes.
