Abstract: 1,063,505. Seaming non-metallic sheet material. CONTINENTAL CAN CO. Ltd. Jan. 6, 1965 [May 27, 1964], No. 594/65. Heading B5K. [Also in Division B8] A head for spin welding a closure 33 of plastics material on to a container 29 includes a non- rotatable sleeve 59, depending from a support 46, in which a cylindrical member 61 is axially slidable and urged downwardly by a spring 65 to grip the container top and hold it firmly on a platform 43 before a closure engaging chuck 77 is spun to effect the weld. The chuck is axially movable in a tubular carrier 71 mounted in a bearing 69 and rotated by a drive shaft 47 when normally disengaged clutch members 52 and 74 are brought into engagement. The clutch member 52 is loosely but non-rotatably attached to the drive shaft and is urged to a lower position by a spring 56, and the chuck is urged to a lower position by a spring 85. A central pin 86 and an offset drive pin 87 depending from the chuck engage holes in the closure. In operation, the platform 43 is raised, or the head lowered, and the chuck is brought into engagement with the closure before the member 61 engages the container, and further movement of the container towards the head brings the member 61 into contact with the container. The chuck is then forced upwards against the spring 85 and the member 61 moved upwards against the spring 65 whereupon the clutch members 52 and 74 are interengaged and the chuck rotated. The chuck may have a friction pad on its lower surface instead of the projecting pins described.

Abstract: 1,153,222. Fractional distillation. FARBENFABRIKEN BAYER A.G. 5 Jan., 1967 [7 Jan., 1966], No. 725/67. Heading BIB. Liquid mixtures are rectified in an apparatus comprising a heated perpendicular cylinder 1 surrounding a rotary fluted condenser tube 8 and rotary arms 12 with hinged wipers 11 which distribute the liquid mixture over the internal surface of the cylinder, the area of the external wall of condenser tube 8 being equal to the area of the internal surface of cylinder 1. The condensate is flung off the edges 16 of truncated cones 13. The lower end of the apparatus is connected to a boiler, e.g. a film evaporator. The upper end of the apparatus leads to a reflux condenser. Heating fluid is forced upwards through a jacket 4 surrounding cylinder 1, this jacket being provided with helical baffle plates 5. Cooling fluid is introduced through pipe 9 at the top of condenser tube 8, flows down the channel between displacement member 15 and the wall of tube 8, and is discharged through pipe 10. The rates of flow of the heating and cooling fluids are adjusted by governors so that the temperature-difference between these fluids and the films of liquid on the surface of cylinder 1 and of the condenser, respectively, is constant over the whole length of the apparatus. A condenser of star-shaped cross-section is described. Reference is made to the separation of dimethylphthalate and diethylphthalate.

Title: Method and apparatus for encasing sausage or the like encased meat product
IPC: A22C11/02
Filed: 1977-01-10
Abstract: For filling a tube (20) with a product, a rotatable filling pipe (18) is provided over which the folded-up tube extends. The product is pumped or moved through the filling pipe into the tube. A damming and distributing body (38) connected to the filling pipe is arranged in the tube downstream of the discharge end (40) of the filling pipe in order to distribute the product in the tube and to increase the pressure in the filled tube. The damming and distributing body is connected via a carrier (32) to a rotatable drive arranged on the end, opposite the discharge end, of the filling pipe. The rotating damming and distributing body exerts a torque on the product in the tube so that, by rotation of the tube, a tube element filled with the product is produced. In the above-described manner, the product is readily distributed in the tube and the pressure of the product in the tube is increased. <IMAGE>

Abstract: 1521341 Charge-coupled devices SIEMENS AG 9 Jan 1976 [11 Jan 1975] 00737/76 Heading H1K The direction of charge transfer in a twophase biased-channel CCD comprising an n-type layer 6 on a p-type substrate 1 and two electrode levels with adjacent electrodes of upper and lower levels (e.g. 31/41; 32/42, &c.) connected is determined by the magnitude of a fixed bias applied between all the electrodes and the substrate. The critical bias value is given by the expression (where e = the electron charge, N L  = layer doping concentration (atoms/cm.<SP>3</SP>), N s  = substrate doping concentration (atoms/cm.<SP>3</SP>), d= layer thickness (cm.), # 0  = dielectric constant of free space, # s  = dielectric constant of substrate material). If the applied bias (either to the electrodes or to the substrate) is less than this value charge transfer occurs within the layer 6 from right to left as viewed in Fig. 3. If the applied bias exceeds the critical value charge transfer is of the biased-channel type within the substrate 1 and from left to right. The invention is applicable to one-dimensional first-in-last-out storage registers or to two-dimensional arrays.

IPC: G10L13/00
Filed: 1996-03-07
Abstract: A channel bank speech synthesizer for reconstructing speech from externally-generated acoustic feature information without using externally-generated voicing or pitch information is disclosed. An N-channel pitch-excited channel bank synthesizer (340) is provided having a first low-frequency group of channel gain values (1 to M) and a second high-frequency group of channel gain values (+1 to N). The first group controls a first group of amplitude modulators (950) excited by a periodic pitch pulse source (920), and the second group controls amplitude modulators excited by a noise source (930). Both groups of modulated excitation signals are applied to the bandpass filters (960) to reconstruct the speech channels, and then combined at the summation network (970) to form a reconstructed synthesized speech signal. Additionally, the pitch pulse source (920) varies the pitch pulse period such that the pitch pulse rate decreases over the length of the word.
