Abstract: 1282328 Feeding biscuits between endless conveyers BAKER PERKINS Ltd 9 Dec 1970 [21 Oct 1969] 51587/69 Heading B8A Apparatus for varying the number of lanes of biscuits 1 being fed on an endless conveyer belt surface 5, comprises a number of inclined exit channels leading to the conveyer, each defined between respective guides, platforms 13 for the reception of biscuits 1 from each lane being fed, each platform 13 being mounted to tilt about an axis parallel with the direction of feeding so as to cause a biscuit to slide sideways into an associated exit channel, and cam controlled mechanism for co-ordinating the sequence and direction of tilting of the platforms in such a way, that substantially equal numbers of biscuits pass along each of a number of exit channels different from the number of platforms. As shown, there are two groups of four input lanes each feeding a respective platform 13. Leading from each of the latter is a respective platform 16, each of which is tapered in plan view and is of equilateral triangular (base downward) shape in crosssection. Each tapered end of the platforms 16 is disposed between a pair of exit channels 20. The eight input lanes thus feed ten exit channels. The lateral tilt of the platforms 13 is brought about by links 29 and 30, to cams 31 (only one set of links 29 and 30 shown in full lines in Fig. 3). The arrangement may be modified to feed 12 or 16 exit lanes. In a further arrangement, 4 input lanes may be reduced to 3 exit lanes.

The shoots can be emptied into funnel 14 one after another. The upstream ends of the walls (15, 16) are disposed such that alternative ones of said ends are at a greater distance from the end of the table 3 at which the funnel 2 is located than the other wall ends, to ensure that all the channels on table 3 receive objects from funnel 2. Object level control means in the form of a vane (not shown) is located between the funnel 2 and the channels to prevent objects being fed into the channels in double layers. The walls (15, 16) may be attached to a cover (not shown) which is located over the table 3.

Abstract: 1307132 Dewaxing petroleum fractions ESSO RESEARCH & ENG CO 30 Oct 1970 [13 Nov 1969] 51707/70 Heading C5E In a process for dewaxing a petroleum fraction 2 the oil is cooled by passage through a chilling zone 3 which comprises a number of stages 4 and cold dewaxing solvent from the lines 11 is injected into the oil at a velocity of at least 50 feet per second whilst the mixture is continuously agitated by means of a rotating impellor 12 having a tip speed of at least 300 feet per minute so that substantially instantaneous mixing and cooling occurs with the temperature in each stage remaining substantially constant. The solvent is injected through jets having diameters of # inch or less and a length to internal diameter ratio of at least 20 : 1 and disposed so that the jet velocity decays to about the tip velocity of the mixing impellors by the time that the jet flow reaches the vicinity of the maximum impellor discharge velocity. The feed, which suitably boils between 500 and 1300 F., e.g. a lubricating oil fraction, is passed upwardly or downwardly through a mixing tower having 6 to 50 stages so that it is cooled at an average rate of 1-10 F. per minute. Suitable solvents are propane, ethane, butane, dichloromethane and/or dichloroethane, or a mixture of methyl ethyl ketone and methyl isobutyl ketone with each other or with benzene or toluene. After leaving the cooling tower the slurry of wax crystals formed can be further cooled by a scraped surface, e.g. to 0 F., before filtering at 15.

Abstract: 1446937 Protective arrangements ELECTRICITE DE FRANCE (SERVICE NATIONAL) 8 Nov 1973 [9 Nov 1972 2 Nov 1973] 51884/73 Heading H2K An automatic system, Fig. 2, for isolating a faulty section T4 of a medium voltage electrical power distribution network and restoring service to the rest of the network comprises, between a normal and an auxiliary power source 51, 52 at opposite ends of a network divided into two parts by a cut-out point 129, distribution stations P 1  to P 5  and C 1  to C 3 , provided with fault detectors and connected in the network, each station being provided with cut-out switches for automatically breaking the network in case of a fault and isolating the faulty section, power being fed to stations on either side of the faulty section then from the normal and auxiliary power sources respectively. At least some stations, Fig. 3, have in association with the cut-out switches a service restoration device 110 comprising a transmitter 114 armed by a fault detector 112 in the absence of voltage in the network and actuated by fault detectors 116, 117 when fault current passes to deliver a position pulse at a time instant defined by a time delay 120 dependent upon its position in the network and a receiver 115 responsive to such position pulses to pass them to selectors 123, 124 associated respectively with the normal and auxiliary power sources, which selectors step in accordance with the received position pulses to a final position which defines the faulty section of the network and causes operation of the appropriate cut out switches to isolate the faulty section. Power is then restored to the rest of the network. The signal from the transmitter 114 is an audio frequency pulse which is fed to the low voltage terminals of the power transformer 105 of the distribution station. The final position of the selectors may be used to control a light signal which indicates the position of the fault in the network. Reversing means are associated with the selectors to take account of changes in direction of power flow. Embodiments of the invention applied to feeder lines are described, and in one case, Fig. 8, not shown, a third power source is available.

Title: A magnetic device.
Inventor: KAENEL REGINALD ALFRED
IPC: G11C19/10
Filed: 1966-11-29
Abstract: 1,158,182. Domain stores. WESTERN ELECTRIC CO. Inc. 29 Nov., 1966 [30 Nov., 1965], No. 53383/66. Heading G4C. [Also in Divisions H3 and H4] In a storage device comprising a magnetic medium through which data in the form of locally reversed magnetic domains is propagated, provision is made to reverse the direction of propagation when the first domain reaches the output end, if a utilization circuit is not ready to receive the output. As shown, multifrequency signals from a subscriber's pushbutton telephone are converted at 20 into pulses on 2 out of 7 lines a to #. Each pair of pulses energizes a corresponding line pair such as 19C, which coact with a strobing pulse on a line 17 to locally reverse the direction of magnetization of a domain in a wire 12. Further strobing pulses operate a driver 15 pulsing a winding 16, causing the reversed domain to shift to the right. At each shift the driver reverses a domain in a second wire 11 and shifts any previously reversed domains in that wire to the right. When the reversed domain in the wire 12 passes the coil 14 it sends a pulse to the driver inhibiting reversal of further domains in the wire 11. Thus the number of reversed domains is equal to the number of shifts required to bring the reversed domain in the wire 12 to the coil 14, and corresponds to the selected digit. The reversed domans are read out from the wires 11 and 12 at 40a and 40b respectively when required and represent the correct number of dialling pulses for a digit and an interdigit spacing respectively. Where a reversed domain is read out it sets an output busy trigger 34 which enables an AND gate 51, so that the next domain is detected by windings 44 and operates a driver 16 to cause the direction of shifting to reverse. Reverse shifting continues until a reversed domain reaches the input position or until a new clock cycle is initiated, at which point forward stepping is again initiated. Trigger 34 is reset periodically after sufficient delay to ensure the utilization circuit is ready to receive the next pulse. A circuit enables an AND gate 46 for a predetermined longer period to effect the required interdigit spacing.
