Title: A breaker bar assembly for severing a moving web
IPC: B65H19/26
Filed: 1960-08-15
Abstract: 891,315. Severing by tearing. FMC CORPORATION. Aug. 15, 1960 [Oct. 9, 1959], No. 28157/60. Class 31 (1). [Also in Group XVI] A breaker bar assembly for severing a moving web between two rollers comprises a bar movable into sliding frictional engagement with the web to impose tension on the part of the web which has advanced past the breaker bar to break the web between the bar and the roller on to which the web is being fed. As shown, a web W unwound from a parent roll passes through mechanism F where it is provided with evenly spaced transverse lines of perforations and then through mechanism G where it is slit longitudinally into strips, the strips being wound in the forms of rolls 24a &c. on to core sections 12a &c. which are traversed past a winding station D by means of a pair of endless chains 18. When each roll has been wound to the desired diameter, the end 76 of a camoperated pivotally-mounted breaker bar 72 is moved into engagement with the web to apply tension to the part of the web between the bar and the roll and thereby sever the web along a line of perforations. The rolls, as they are being wound, are driven by belts 30 passing round drums 32, 34, the shaft 36 of the drum 32 being rotatably mounted in bearings carried by cam-operated slide blocks 38 and the shaft 42 of the drum 34 being mounted in bearings carried by swingable brackets 44.

Title: Improvements in or relating to beverage maker
IPC: A47J31/043
Filed: 1945-10-26
Abstract: 604,320. Tea, coffee and the like. QUALITY HARDWEAR & MACHINE CORPORATION. Oct. 26, 1945, No. 28299. Corivention date, Jan. 1. [Class 129] [Also in Group XVII] An automatic beverage maker, such as a coffee maker, comprises a lower container 10 in which water, after being heated up and a substantial pressure raised above the water level 17, is transferred rapidly up a tube 30 into an upper container 11 where it passes through the coffee. Cooling of the lower container creates a partial vacuum therein, and the beverage passes into the container 10, whence it is dispensed after removal of the container 11. The latter is effected by lifting a knob 54 which raises a lid 52 and the container 11, which are secured together by a spring 56. Pressing a plunger 55 downwards releases the spring 56 from a beading 53, and the lid may be detached and used on top of the container 10. In Fig. 1, during the heating up of the water 17, the water is prevented from passing up the tube 30 by a vent 50 releasing vapour from the container 10, until the water reaches a pre-determined temperature when the pressure rise is sufficient to overcome the effect of the vent and hot water rushes up the tube 30, passes out of a hole 47 into the container 11. A valve 63 closes a hole 62, due to pressure in the container 10, until the hot water has passed to the container 11, the heating means 22 switched off and the consequent cooling of the container causes a partial vacuum therein and the valve drops allowing the water to pass through a basket 40 containing coffee, the brew settling in the container 10. The heating means may be thermostatically controlled. The containers 10, 11, may be of stainless steel, or other material, and the base 18 be of insulating material. The basket 40 has a beaded edge 46 which is slidable laterally in beaded rails 45 and can thus be removed from the container 11. In a modified arrangement, the basket 40 and valve 63 are dispensed with, and the upper part 31, of the tube, has wire-mesh insertions through which the hot water passes into the container 11, in which the coffee is placed, the brew returning through the insertions when the partial vacuum is formed in the container 10.

Title: Search-minimized optimum processor
IPC: G06F17/30
Filed: 1970-06-11
Abstract: 1317053 Trainable processors TEXAS INSTRUMENTS Inc 11 June 1970 [30 June 1969] 28363/70 Heading G4R In a trainable processor, similar to that described in Specification 1,264,387, training functions developed in the course of training are stored in a random access memory. For each set of input signals representing a training function key signals are generated to designate node locations defining a branch of a tree storage array. The key signals and training function are stored in the tree array in the random access memory. This arrangement reduces the number of storage locations required since a storage location is assigned as needed for each training function, whereas in the prior processor a location is provided uniquely for each of the possible combinations of all the quantization levels of the signals used in training. During training the processor is fed with a succession of sets of input signals u i  and a corresponding series of signals representing the desired response z i  of the processor to the signals u i . The signals are quantized and used to develop key signals which address locations in the memory. Quantized signals representing the output x i-1  of the processor in response to prior training signals are also used in the development of the key signals. The selected locations' contents are adjusted in accord with z i  and u i . The branch in the tree storage is defined by the key signal, and this signal is compared with keys representing previously defined branches, if any. If such a path has previously been defined the content of the last storage location in the path is adjusted to correspond to the present input signal set. The adjustment to the content takes the form of adding the value of the desired response z i  to the current content to provide a result which replaces the current content. The number of times that the location has been adjusted is accumulated, and the processor output signal x i  is determined by dividing the adjusted content by this number. If no corresponding path has been previously defined the key signal defines a new path in the tree. During execution, the processor provides an output signal x i  in response to an input u i , x i  being obtained from the tree storage. If the processor encounters an untrained input it replaces this input by the value of the previous output.

Title: Improvements in or relating to photographic camera shutter mechanism
IPC: G03B9/08
Filed: 1948-01-07
Abstract: 677,314. Photographic shutters provided with diaphragms. INTERNATIONAL POLAROID CORPORATION. Jan. 7, 1948 [Feb. 7, 1947], No. 28419/50. Divided out of 677,228. Class 98 (i). A photographic camera shutter comprises a rotatable diaphragm disc having apertures of different diameters, a rotary closure element for closing the camera exposure aperture when at rest, means for varying the extent of the rotational movement of said element and thereby varying the exposure time, and common means for rotating the diaphragm to change the aperture and for actuating the means for varying the exposure time. As described, the shutter is of the kind substantially identical with that described and claimed in Specification 677,228 to which reference is made, except that means for effecting time and bulb exposures are not described, and is modified as shown in Fig. 2 so that a single adjustment for different light values alters both the shutter speed and diaphragm aperture. An apertured diaphragm plate 256 having teeth 276 and a cam 296 is rotated by a knob 274 through a pinion 272 so as to bring a selected light value " 2 "-" 14 " in the window 266. This rotation brings a stop aperture into register with the exposure aperture 270 where the plate is held by a ball catch 300 while rebound springs 260, 262 for exposures less than <SP>1</SP>/ 7  second, which springs are carried on pivoted arms 278, 280 urged against the periphery of the plate 256 by springs 286, 288, are moved into or out of the path of the shutter blade lug as determined by followers 290, 292 on the pivoted arms engaging the cam 296, a fixed rebound spring 264 being provided for exposures of <SP>1</SP>/ 7  second, so that exposures corresponding to different light values are given by different aperture and shutter speed combinations. Instead of separate rebound springs there may be used a single circumferentially-movable spring as in the embodiment of Specification 677,228, a spring of adjustable stiffness or a spring having several portions of different stiffness, which portions may be moved into the path of the blade lug. Alternatively a single rebound spring could be mounted on the shutter blade and arranged to engage adjustably positioned rigid lug members.

IPC: C12P19/42
Filed: 1957-09-13
Abstract: Cobalamins are obtained in a continuous process which comprises fermenting a suitable liquid nutrient medium under substantially anaerobic conditions with a cobalamin producing species of the genus Propionibacterium in a first zone and while adding nutrients to this zone, passing cell-containing medium from the first zone into a second zone at such a rate as to maintain the concentration of cells and volume of medium in the first zone substantially constant, contacting the cell-containing medium in the second zone with oxygen preferably in sufficient quantities to give microaerobic fermentation conditions, while withdrawing cell-containing medium containing cobalamins from the second zone at such a rate to maintain the concentration of cells and volume of medium in the second zone substantially constant and thereafter concentrating or recovering the cobalamins contained in the cell-containing medium withdrawn from the second zone.  A suitable nutrient medium comprises a source of assimilable nitrogen, e.g. corn steep liquor, a source of assimilable carbon, e.g. glucose or lactose, and a source of assimilable cobalt, e.g. cobalt chloride or nitrate.  Species of the genus Propionibacterium which may be utilised are P. freudenreichii, P. shermanii or P. technicum. Anaerobic conditions may be maintained in the first zone by carrying out the fermentations under an atmosphere of nitrogen or a non-oxidising gas.  Contact with oxygen in the second zone may be effected by passing oxygen or air through the medium or by mechanical agitation.  The preferred fermentation temperature is 30 DEG C. and preferred pH range 6,5-7,5.  The process is exemplified in detail.
