Abstract: 731,643. Sawing. DELETAILLE, E. A. A. L. July 3, 1953 [July 4, 1952], No. 18541/53. Class 145. A reciprocating log Saw having a single blade or ganged blades is driven by a hypocycloidal gear mechanism comprising a driven crank disc 2 with a crank pin 3 on which the planet wheel 4 rotates in engagement with a sun wheel 5 rigidly mounted in a casing 1 and the pitch diameter of the planet wheel 4 is half the pitch diameter of the sun wheel 5 so that a sleeved crank pin 6 on the planet wheel imparts a straight-line reciprocating motion to the blade or blades. A balance weight 10 is fitted on the disc 2 and another balance weight 11 is fitted on the planet wheel 4. The saw may comprise a pair of pillars 14 on which a cross member 15 is vertical adjustable and a single gear mechanism may operate a saw frame sliding on the member 15 or a pair of mechanisms 21, 22 connected by a chain drive 28 may have sleeves 30 carrying one or more blades fitted on their crank-pins. For tensioning the blades, one mechanism may be adjustable on the cross-member by a screw 24 and locked in adjusted position by bolts 27. In the vertically-arranged saw shown in Fig. 6, a blade-carrying frame 32 is reciprocated by a pair of mechanisms 34, 35 connected by a gear drive or by four driving mechanisms, two at the top and two at the bottom of the frame, or by a single mechanism. The interconnection of the mechanisms, so that they run in synchronism, may also be by means of coupling rods or by electrical or electronic means. Where pairs of mechanisms are used, they may be arranged slightly out of phase so that the blade oscillates slightly during reciprocation to prevent jamming in the kerf; with this arrangement, the distances between the two crank pins will vary during reciprocations but the variation is small enough to be within the elastic deformation range of the blade.

Title: Encoding and decoding speech signals
IPC: H04K1/00
Filed: 1976-05-06
Abstract: In the method for encrypting analog speech signals with the aid of orthogonal matrices, the encrypted signals can be transmitted via a channel with restricted bandwidth. The encryption is carried out in a digital intermediate stage (ZV, S1, ZW1, ZW2, S2, M, ROM, A) in which digitised samples of the signal (E) to be encrypted are transformed using an orthogonal matrix. A specific re-arrangement of the order of the transformed samples and their subsequent transmission to the receiver as a continuous signal are carried out simultaneously. The matrix transformation and the aforementioned re-arrangement together represent an encryption method which is immune to synchronisation errors between samplings at the transmitting and receiving ends. <IMAGE>

Title: Improved method of and means for the cleaning or sweeping, by blowers, of steam generators, superheaters, water heaters, air heaters or the like
IPC: F28G1/16
Filed: 1928-06-27
Abstract: 303,489. Soc. Anon. des Etablissements Neu. Jan. 6, 1928, [Convention date]. Cleaning pipes. - Steam generators, superheaters, water heaters, air heaters &c. are cleaned by pulsations of steam or compressed air issuing from nozzles 7<a>, Fig. 3, of a blower pipe 7 which is rotated intermittently by the pulsations by means of a pawl 10 carried by a spring-actuated plunger 12 and engaging a toothed wheel 9. The blowing is reduced to its useful angle of sweeping by a cylindrical obturator 17. The pulsations are produced by the apparatus shown in Fig. 4 in which air from a compressor entering at 20 passes by an aperture 33 and tube. 24 to a cylinder 25 containing a piston 26. Upward movement of piston 26 uncovers an aperture 32 thus establishing atmospheric pressure in the space 23 above a piston 22 which is then moved by the compressed air and opens a valve 19 admitting air to the blower. The movement of piston 26 also displaces a movable weight 28 which further raising a plunger 29, equalizes the pressure on the two sides of piston 22 so that the valve closes and the piston 26 and weight 28 resume their initial position after which the cycle is repeated. Specification 283,858 is referred to.
