Patent GB-838247-A (GB)
Title: Improvements in or relating to transistor circuit arrangements
IPC: G11C19/28
Filed: 1957-11-22
Abstract: 838,247. Electronic stepping registers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 22, 1957 [Nov. 27, 1956], No. 36486/57. Class 106 (1). In a transistor chain circuit in which the presence or absence of stored free charge carriers in the base zone of a transistor determines the free charge storage in the base zone of a succeeding transistor by means of pulses fed to the transistor collectors at predetermined time intervals, the collector of the preceding transistor is connected through a resistor conducting in both directions to the base of the succeeding transistor, the value of this resistor together with that of a resistor in the collector circuit of the preceding transistor being sufficiently large to prevent any appreciable leakage of free charge carriers from the succeeding transistor in the interval between successive pulses supplied to the two transistors. In the circuit shown, Fig. 1, odd and even transistors receive pulses alternately from separate sources A, B, Fig. 2, each pulse being followed by a charge-erasing pulse A', B' applied to the bases. If initially no transistor contains free charge carriers, the first pulse A will charge the bases of even transistors 2, 4, 6 by current flow through resistors 19, 21, 23. When the following pulse B is received, these transistors will be highly conductive and no charge will be imparted to the bases of the odd transistors 3, 5. If free charge carriers are introduced into transistor 1, e.g. by a light pulse, when the next pulse A is supplied, a current I 1  will flow, thus preventing a charge being imparted to transistor 2: thus the next pulse B will not cause transistor 2 to conduct (see absence of I 2 , Fig. 2) but will charge transistor 3 which then conducts (current I 3 ) upon receipt of the next pulse A and so on. Thus the charge imparted to transistor 1 is shifted along the chain as absence and presence of charge alternately (see also I 4 -I 6 , Fig. 2). The circuit may be used for shifting binary information, e.g. in a calculating-machine or automatic telephone system. Specification 835,907 is referred to.

Title: Confection Coating Machine and Apparatus for Use therewith.
IPC: A23G3/20
Filed: 1966-08-16
Abstract: 1,151,121. Coating with comminuted material shaped products, e.g. frozen moulded confections. FMC CORP. 16 Aug., 1966 [24 Aug., 1965], No. 36551/66. Heading A2A. Apparatus for coating shaped products, e.g. frozen, moulded confections on sticks, with comminuted coating material comprises an upwardly inclined screw conveyer 64, which feeds coating material, from a supply bin 62, into the coating chamber of a coating machine D, e.g. of the impeller type described in Specification 1,048,842. The screw conveyer is provided with an upper inlet opening 123 and a lower inlet opening 125 and with a baffle 124 (near the lower edge of the upper inlet opening 123) to intercept and deflect any coating material tending to flow out of said upper opening when coating material is being fed from the bin into the screw conveyer 64 only through the lower inlet opening 125. The apparatus also comprises a discharge trough 66, which is positioned to receive excess coating material from the coating chamber and return it to the conveyer 64, or to the bin 62 if the conveyer is full. The screw 114 of the conveyer 64 may be rotated, e.g. through reduction gearing, by a variable-speed D.C. electric motor 180. The screw may vary in pitch, e.g. so that its capacity for handling coating material at the upper inlet opening is twice that at the lower inlet opening. The conveyer 64 and bin 62 are pivoted, at 82, to a carriage 60, e.g. so that they can be turned into an inoperative position indicated by phantom lines. The carriage 60 has adjustable telescoping legs 70 terminating in wheels 74 and castors 76. In coating frozen confections on sticks S, the confections, in their moulds and with their sticks pointing upwards, are conveyed from forming apparatus C, in the direction of the arrow T, beneath an endless travelling conveyer 22 having grippers, which are lowered to grip the sticks at a de-frosting station E and then raised to remove the loosened confections from the moulds. The conveyer 22 then carries the confections to an oiling station H and thence to the coating machine D, where comminuted coating material is hurled at the oiled confections by rotating impellers.

Abstract: 1,235,278. Grinding; end mills. FRANZ KUHLMANN K.G. PRAZISIONSMECHANIK UND MASCHINENBAU. 21 July, 1969 [22 July, 1968], No. 36551/69. Headings B3D and B3K. A device for supporting a die sinking cutter 28 during grinding comprises a rectilinearly moveable grinding table 3, means for converting the table movement into rotary motion for a shaft 5 drivingly coupled to a further shaft 10, an arm 16 pivoted about the further shaft 10, adjustably supporting an indexing head 26, and means for transmitting rotary motion of the further shaft 10 to an indexing head spindle 27 for rotating the cutter 28 when supported thereby, so that a grinding wheel (not shown) may engage an edge of the cutter 28 on movement of the table 3. A steel band 14 held in a holder 13 engages a friction wheel 6 on the shaft 5, so that on moving the table 3 motion is transmitted to the shaft 5, and hence, through gears 7-9 and a further steel band 33, to a friction wheel 24, which drives the spindle 27. The cutter 28 is located for grinding by sliding the head 26 axially of the arm 16, a locating feeler 40 being provided, supported by a detachable holder 38, while gauge blocks 43 allow setting to a required cutter radius. For grinding, the table 3 is placed in a starting position fixed by an adjustable stop 44, the holder 38 is detached, and the grinding wheel is positioned. On moving the table 3 the arm 16 is pivoted for grinding of the hemispherical tip region 28a of a chosen cutter edge, until engagement of stops 17, 18 limits pivoting. The arm 16 is then moved rectilinearly with the table 3 to grind the axial region 28b of the cutter edge.  An exemplary die-sinking cutter, Fig. 3, is formed at its tip with spherically disposed teeth 28a, one of which has an edge 28c, projecting to the axis of the tool.

Filed: 1968-08-06
Abstract: 1,199,678. Stringed musical instruments. MICRO FRETS CORP. 6 Aug., 1968 [19 April, 1968], No. 37409/68. Heading G5J. Each string 150, Figs. 2 and 3, of a stringed musical instrument of the type having a fingerboard, has a longitudinally displaced or displaceable separate support nut as shown at the end of the fingerboard 112. Each nut comprises a roller 128 upon which the string rests, and a string guide 130, at the top of which is a yoke 132, having therein a groove 134 for receiving the string. The string tension depends on the height of the roller 128 above the support plate 122, which is controlled by the tension screw 124. A slot 136 in the guide 130 facilitates longitudinal adjustment of the nut position before final attachment to the neck through the fixed support block 138. The dotted line in the Figures represents the position normally occupied by a conventional one-piece linear support nut. The individual support nuts are disposed on either side of this, tuning being effected by adjustment of the nut position and thus the string tension. In a modification (Figs. 4 and 5, not shown) a longitudinal adjustment screw (240) operating on the string yoke (226) is located generally parallel to and longitudinal of the fingerboard. In a further modification (Figs. 6-10, not shown) each nut (320) slides in one of several channels in a common support (314) on the guitar neck. The string rests in a groove (324) or passes through a hole in the nut. In another embodiment, Fig. 11, the support nuts 420 are fixed non-adjustably in predetermined locations about the conventional linear nut positions. The invention may be applied to fretted or non-fretted instruments.

Title: Air cooled condenser for the vapours from a distillation column
IPC: B01D5/00
Filed: 1958-11-21
Abstract: A condenser for a distillation column 1 is built up of air-cooled units 4 arranged in an annular channel around the upper part of the column, each unit comprising finned-tubes 5 in an air-duct 7, a fan 8 for inducing a stream of air through the duct, and a movable flat 14 for controlling the proportion, in the stream of air, of fresh air to recirculated air, i.e. air which has already passed through a preceding unit, whereby the temperature of the condenser can be regulated.  In the apparatus shown, there are four condenser <PICT:0900406/III/1> <PICT:0900406/III/2> units 4a . . . 4d, arranged in the annular channel formed by the wall of the column 1 and the outer wall 16.  The vapours from the head of the column are distributed to the units through conduits 2a . . . 2d.  Each duct has an outlet-opening 11 leading into the annular channel, and an outlet-opening 12 leading to the atmosphere.  A flap 14 is mounted for adjustment about a vertical axis at each of the common edges of openings 11 and 12.  If the openings 11 are closed by the flaps 14, the fans 8 draw in fresh air from the open top of the annular channel, impel it through the condenser units 4, and then discharge the air through openings 12 to the atmosphere.  If it is desired to use mainly recirculated p  air, the openings 12 are closed by flaps 14.  But with the flaps 14 in the position shown, the condenser units are fed partly with recirculated air and partly with fresh air.  The flaps may be automatically adjusted by electrical relays controlled by thermostats in the air-ducts so as to maintain a uniform temperature of the stream of air flowing over the finned tubes of the condenser.

Title: Method for preparing ribonucleoside-5'-phosphates or their salts from ribonucleosides
IPC: C07H19/04
Filed: 1963-09-24
Abstract: A process for selectively introducing a phosphate group into the S1-position of a ribonucleotide comprises blocking the 21- and 31-positions by reacting the ribonucleotide with an aliphatic, alicyclic or aromatic aldehyde or ketone in the presence of a phosphorus-containing compound which catalyses the blocking reaction and is ROP(O)(OH)2, P(O)X3, P(O)(OH)X2, P(O)(OH)2X, PX5, (where R is monovalent hydrocarbyl which may be substituted, X is halogen and n is zero or a whole number), metaphosphoric acid, orthophosphoric acid, P2O5 or a mixture of any <FORM:1056428/C2/1> 2 or more of such compounds, and subsequently phosphorylating the S1-position in known manner without separating the 21,31-O-hydrocarbylidene-nucleotide from the phosphorus-containing compound.  The phosphorus-containing compound may itself be used as phosphorylating agent or a further agent may be added.  The blocking reaction may be effected in the presence of a dehydrating agent which is a compound having a double bond conjugated with a carbonyl group, e.g. benzalacetone, dibenzalacetone or mesityl oxide, a compound having an acetylenic bond, a compound having an alkoxy radical and a double bond on the same carbon atom, a compound having 2 alkoxy groups on the same carbon atom, a cyclic ether or an orthoester.  The phosphorylation may be effected in the presence of an organic base and/or a condensing agent such as a carbodiimide, cyanamide, ketenimide or nitrile. Solvents may be used.  The blocking group and the ester group if any on the phosphate moity may be removed in either order, e.g. the former by acid hydrolysis and the latter by alkaline hydrolysis or catalytic reduction. Salts may be formed and may be converted to the acid form by ion-exchange procedures. Uridine diphosphate and its Ca salt are obtained in Example 44. Specified nucleotides include nicotinamide nucleotide as well as the conventional naturally occurring ones.  Reference has been directed by the Comptroller to Specification 1,013,164.
