Inventor: CASTELLUZZO JAMES
IPC: B26B1/08
Filed: 1987-08-06
Abstract: A utility knife (10) employs a slide (16) having a cantilevered lever (138) for capturing a blade (18) therein. A leading blade in a reservoir (24) is capturable by the slide (16) using a tooth (158) resiliently affixed to the slide (16) which is positioned to enter a locking hole (82) in the blade (18). The tooth (158) may be withdrawn from the hole (82) in the blade (18) whereby the blade (18) may be removed for reversal and reinsertion or for discard. When the captured blade is removed, the slide (16) may be returned to the loading position for capturing the next blade from the reservoir. As long as a captured blade (18) is engaged by the tooth (158), the slide (16) is prevented from returning to the loading position, and the loading blade in the reservoir is prevented from advancing.

Abstract: A carrier recovery circuit comprises first and second mixers (14,15) for mixing a received PSK signal with first and second reference signals. A remodulator (12) extracts a preamble from each burst of the PSK signal and supplies the extracted carrier to a carrier recovery means (13) to cause it to derive a reference carrier from the extracted preamble. A phase detector (18) is connected to the outputs of the first and second mixers (14,15) for detecting a phase difference between the PSK signal and the reference carrier, the detected phase difference being applied to a resettable noise reduction circuit (19,20) for reducing amplitude fluctuations contained in the phase difference, the noise reduction circuit (19,20) being arranged to be reset in response to each of the bursts to discharge energy stored as a result of the noise reduction and eliminate interburst phase errors which occur as a result of interburst frequency variations. A variable phase shifter (16) controls the phase of the reference carrier in accordance with the output of the noise reduction circuit (19,20) and supplies quadrature versions of the phase controlled carrier to the first and second mixers (14,15) as the first and second reference frequency signals.

Abstract: Digital-to-analogue converter especially intended for controlling video image lines. This high-speed, medium-precision converter is constructed so as to provide a sizeable output dynamic which is not overly limited by the threshold voltages of the NMOS technology transistors used in this converter. To obtain this sufficient output dynamic with moreover a sufficient low level, sufficiently constant to drive a bipolar follower stage, there is provision for an output stage of the converter with a capacitor (C) which makes up for the grid/source voltage drop of an output transistor (T1). The capacitor (C) is periodically recharged during line flybacks or frame flybacks of the video signal controlled by the converter. <IMAGE>

Abstract: A chamfering device for a hand-held power tool driving a rotary file or cutter member (10) having a mainly conical cutting head (11). The device comprises a portion (16, 17, 19) which with a play encloses part of the circumference of the cutting head and which has an opening (20) which exposes the remaining part of said circumference for engagement with a workpiece (21). The cutting depth during said engagement is determined by support surfaces (18, 22, 23) intended for contact with the workpiece in the axial and radial directions relatively to the axis of rotation of the cutting head (11). 
     By means of a first part (2), the device is intended to be attachably and removably fastened to a front portion (1) of the power tool, in an axially adjustable position. A second part (12) is rotatably connected to the first part (2) and comprises the opening (20) and the support surfaces (18, 22, 23). At least one radial support surface (22,23) is so located and designed that, when the chamfering device is moved along a workpiece (21), said surface is, by means of the contact pressure against a lateral surface (25) of the workpiece, guided to follow changes of direction of said lateral surface, whereby the rotatable second part (12) is kept so oriented that the cutting head (11) remains exposed relatively to the workpiece.

Abstract: To restore the direct voltage value in video signals, a signal sampling and integration has previously been carried out. The reference value was held during the video clamping period. To restore the direct voltage value of video signals, a transconductance amplifier (TCA) is now used, the voltage of which is switched over at the rate of video clamping pulses (KL) for setting the operating point (Bias). The output signal of the transconductance amplifier (TCA) is supplied to a holding capacitor (HC), integrated (IG) and used as feedback signal for the transconductance amplifier (TCA). The carrier dispersal of video signals can be suppressed by more than 55 dB and low-frequency interference signals such as hum components in the fundamental frequency can be suppressed by more than 40 dB. <IMAGE>

Abstract: During transformative coding of audio signals, the bits are allocated to the spectrum components for purposes of quantification. After a preliminary approximative quantification, there remains the problem of distributing the still available bits of a data block among the spectrum components, in order to obtain the highest possible precision. The following steps are followed during a process of precise quantification: a) determination of values as absolute values, b) standard conversion of the values obtained by means of a control value, c) summing of all values greater than 0, d) determination of a control value from the saved bits and from the previous sum, e) allocation of the remaining bits to values on the basis of the characteristic values. The invention finds application in audio systems with which a high-quality transmission at a low data speed is sought.

Abstract: In a MAC receiver the device effects a format conversion, going for example from a 16/9 format to a 4/3 format. This is ordinarily obtained by rereading from pixel memories, preexisting in the receiver, at a speed lower than that for writing. With the aim of retaining the normal speed of delivery of pixels at the output of the device, the memory-address generators are modified so that, without modifying the clock speed, reading from the memories is effected with, at regular intervals, rereading of the same value twice in succession. As compared with the pixels which would be obtained by reading at reduced speed (line 50), pixels (line 51) are obtained at normal speed, and the values thus read are then summed in pairs with a weighting (i, j, k, l) which varies with each clock beat (line 52), the same cycle returning periodically with the same periodicity as the rereading operations. <IMAGE>

Abstract: The so-called camera-shake induced artefacts are eliminated by choosing a 2D FT type of imaging method and by choosing a phase coding step which is a multiple of a useful coding step determined by the height of the image field to be represented. It is shown that, after the calculation of the image reconstitution by Fourier transformation, the central image corresponds to the representation of the continuous components of the magnetic moments of the particles situated in an explored cross-section of the body being studied. It is also shown that these components are not affected by any variations in the rate of a cyclic phenomenon which perturbs the images (generally the cardiac cycle).

Abstract: A branched exhaust pipe of an internal-combustion engine (1) has two pipe branches (5, 6), which lead to a primary catalyst (4) and form a bypass to the latter, respectively. The corresponding division of the exhaust gas stream is effected with the aid of bimetal tongues (10a, 10b), which assume the respectively desired position as a function of the temperature of the exhaust gas stream. The primary catalyst (4) is thus only supplied while the exhaust pipe is still cold; overheating of the primary catalyst, which reaches its operating temperature rapidly at low mass flow, is thus excluded due to the automatic blocking of the pipe branch leading to the primary catalyst. <IMAGE>
