Abstract: ABSTRACT OF THE DISCLOSURE       There is disclosed a torque wrench, including a main body, an actuator including a piston/cylinder arrangement and cooperating spool valve which selectively supplies pressurised fluid to either side of the piston member.  The actuator is supported in the main body and adapted to act upon and selectively reciprocate a thrust member relative to the main body, the thrust member being adapted to engage and pivot a torque arm for providing a torque output at an output shaft via a ratchet arrangement incorporated between the torque arm and the output shaft.  The torque arm is supported independently of the thrust member and is not physically connected thereto.  The exposed area of the piston member on a return side thereof is relatively smaller than the exposed area on the opposite or power side thereof, whereby the swept volume during a return stroke is relatively smaller than the swept volume during a power stroke, to thereby produce a low force relatively high speed return stroke and a high force relatively low speed power stroke.          A return spring biases the torque arm to a home position during a return stroke of the piston member.          The torque arm has a curved surface adapted for engagement by a correspondingly curved surface on the thrust member to maintain high force transmitting area contact as distinct from point or line contact.Means are also provided to measure the amount of rotation of the output shaft to allow utilisation of the "turn of nut" technique often used with torque wrenches.

Abstract: PROCESS FOR PRODUCING PRECISION PARTS FROM PHOTOSENSITIVE                   MATERIAL Abstract of the Disclosure A double exposure and double etch technique for producing precision parts from a photosensitive material is described.          The process is described in terms of producing an array of ink jet charge electrodes which comprise a series of small through holes on accurately defined centers.  The process comprises the steps of exposing the photosensitive material through a mask to develop an undersized through hole and heat treating the photo-sensitive material to change its characteristics so that an etchable material is produced in the exposed area.  The material is then etched to form the undersized through hole which is sub-stantially tapered.  The material is then exposed again with a full sized mask including any conductor patterns and the material is again heat treated.  The material is again etched and this etching, in the nature of a surface etch, reduces the taper because of the lower etch rate of the unexposed material as compared to the much higher etch rate of the previously unetched tapered material.

Abstract: ABSTRACT OF THE DISCLOSURE   It is known to generate microwave frequencies by locking the funda-mental output frequency of a microwave oscillator to a multiple or sub-multiple of the output frequency of a highly stable crystal oscillator operating at a lower frequency than the microwave oscillator.  Phase-locked loops are used together with frequency multipliers or dividers.  One problem is that the frequency lock range decreases as successively higher and weaker harmonics are used for locking.  This limits the practical harmonic locking range to multiples of approximately less than ten.  The present invention eliminates this problem and allows microwave signals which have a frequency greater than 10 times the reference frequency to be phase locked without an impractical reduction of the capture range.  As well, in conventional phase locked loop systems which use multipliers, fm modulation which is intentional-ly injected must have a modulation index less than 1Ø  The present invention eliminates this problem and increases the allowed modulation index by a factor N, where this the division ratio of the frequency divider used in the feed-back loop.  The present invention uses a microwave parametric frequency divider to phase lock a microwave oscillator to a stable reference oscillator without the need for frequency multipliers.  The output f1 of an rf oscillator is divided by N and  fed to one input of a phase detector.  The phase detector has another input fed by a reference oscillator of predetermined frequency f2. The phase detector has an output fed to a control input of the rf oscillator which causes the rf oscillator to produce a frequency of Nf2 which is directly fed to the rf output of the apparatus.  Note that no multiplier is required.

Abstract: ABSTRACT:           In a digital transmission system of the type in which a bit stream is divided into consecutive transmission frames and in which extra bits are inserted in given bit position of each transmission frame the bit stream is scrambled in a transmitter terminal station and transmitted via a plurality of regenerative repeaters to a receiver terminal station, in which the transmitted bit stream is descrambled and the inserted extra bits are selected from the bit stream.           Both the scrambler and the descrambler comprise a generator for generating a given fixed scramble pulse pattern. In addition, both the transmitter and the receiver terminal station comprise a transmission clock pulse counter which, on attaining its final counting position, supplies a setting pulse which adjusts the pulse pattern generators in the scrambler and the descrambler to an initial generation state, By chosing a fixed relation between this final counting position and the number of bit positions per transmission frame it is possible to select with simple means the extra bits, inserted in the consecutive transmission frames, in the repeaters and the receiver terminal station without the necessity of first descrambling the received scrambled bit stream.

Abstract: ABSTRACT OF THE DISCLOSURE             In a microwave oven there is described an improved oven wherein the bottom or lower surface of the oven cavity is formed with a recess of non-uniform cross sectional configuration for the purpose of achieving more uniform heating of a food stuff.  In known microwave ovens, a recess of unidorm configura-tion is formed into the lower surface of the oven cavity which results in an uneven heating of the food stuff placed atop a platform or turntable mounted above the recess.  In this inven-tion, the lower surface of the oven cavity is formed with a recess of non-uniform configuration to thereby randomly reflect microwave energy, thereby resulting in the exposure  of the food stuff placed atop the turntable to uniform intensities of microwave energy and thus to more even heating.
