Title: Improvements in or relating to means for securing gates and the like
IPC: E05B65/00
Filed: 1937-05-08
Abstract: 491,335. Gate fastenings. HODSON, C.E. May 8, 1937, No. 13198. [Class 44] In a gate fastening the movable catch member has an adjustable stop which co-operates with a fixed member to support the free end of the gate in the closed position. Fig. 1 shows a depending L-shaped bar pivoted on the gate E at C and with a vertical limb which engages, under gravity, a notch in the edge of a horizontal plate D fixed on the post E<1>. The horizontal limb acts as a counterweight and its end, which may have a nut, serves as a handle to release the fastening. The vertical limb is threaded to receive a nut A which rides on to the upper surface of plate D to support the gate. Fig. 4 shows a bar C the fixed lower end of which acts as a spring biassing the bar to engaging position, movement being limited by a fixed loop E<2>. In a modification the bar is loosely mounted at its lower end and and engages under gravity, the operating knob C3 being off-set to act as counterweight. The nut A may be held in adjusted position by a locknut, and the fixed supporting plate may be independent of the catch plate D.

Title: Processing circuit for chromatic television signals
IPC: H04N9/465
Filed: 1975-04-01
Abstract: 1510316 Colour television; transistor amplifiers INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 1 April 1975 [3 April 1974] 13309/75 Headings H4F and H3T In a colour television receiver for receiving signals which require a switching operation to occur at line frequency, e.g. as in PAL or SECAM (Trade Mark) system, line frequency pulses are passed to a first bi-stable, which provides a signal at half line frequency to control the switching, and to a second bi-stable which controls the phase of the first bi-stable. If the phase of the switching operation is incorrect, the phase of the bi-stables is corrected. In the embodiment shown in Fig. 1 chroma signals C, which include a colour burst either with every line or with alternate lines, pass via a gate 203, which removes the bursts, to demodulators 210, 212 which provide the blue and red colour difference signals. The chroma signals also pass to a gate 204 which is opened at half the line frequency so as to pass only the burst associated with alternate lines to phase locked loop 217-219. Oscillator 219 provides sub-carrier of + 90 degrees phase relative to the B-Y signal. The sub-carrier is shifted - 90 degrees at 222 and passed to B-Y demodulator 210 and also to a demodulator 224. A switch 220 passes the sub-carrier direct or via phase inverter 225 to R-Y demodulator 212, switch 220 being controlled by half line frequency pulses from a bi-stable 226 which is fed with line frequency pulses at input H via a gate 232 which is inhibited if bi-stable 226 operates in the wrong phase. The subcarrier also passes via a second switch 221 direct or inverted (228) to a demodulator 227. Switch 221 is controlled by a bi-stable 229 which is phase-locked to bi-stable 226 and receives line frequency pulses. The output of bi-stable 229 also enables gate 204 which selects alternate colour bursts. Should bistable 226 have the wrong phase so also will bistable 229, and consequently demodulators 224, 227, which receive the colour components of the chroma signals via a.g.c. unit 208 and which normally provide B-Y and R-Y signals respectively, will generate Œ(R-Y) and Œ(B-Y) signals respectively. The half line frequency alternating component in these signals is detected by units 238-242 to provide the inhibit signal to gate 232 until the phase of bi-stable 226 is correct. Units 238, 239 are half line frequency filters. The filters are each as shown in Fig. 4 and each includes a positive feed-back loop 488 to increase the gain and a negative feed-back network to increase the gain at the half line frequency. The network includes resistors 489-492 and 495 and capacitors 493, 494. Resistor 492 is variable to adjust the preferential frequency of the filter.

Abstract: 1461493 9 - # - D - Arabinofuranosyl hypoxanthine nucleotides ICN PHARMACEUTICALS Inc 26 March 1974 13349/74 Heading C2P The invention comprises compounds (I) of the general formula wherein Z is H, a C 1 -C 6  alkyl, C 7 -C 10  aralkoxy or OH group and AP is a phosphorylated 9 - # - D - arabinofuranoside wherein the phosphate group is attached at the 31- or 5<SP>1</SP>- position or to both the 3<SP>1</SP> and 5<SP>1</SP> positions to form 3<SP>1</SP>,5<SP>1</SP>-cyclic phosphates. The phosphorylated moieties (AP) when phosphorylation is at the 5<SP>1</SP>-position may have the structure: wherein R 1  is OH, -O-C 1 -C 6 -alkyl or OM and R 2  is OH or OM where M is ammonium, substituted ammonium (e.g. triethyl ammonium), or an alkali- or alkaline earth metal or other metal which forms a physiologically acceptable compound. When the phosphate group is in the 3<SP>1</SP>-position it may likewise have the structure (R 1 )(R 2 )P(O)O- and the AP group in the 3<SP>1</SP>, 5<SP>1</SP> cyclic phosphate may have the structure wherein R 1  is as defined above. The products may be obtained by reacting the corresponding 9-#-D-arabinofuranosyladenine nucleotide with glacial acetic acid and sodium nitrite in water, e.g. for from 15 to 24 hours at 10‹ to 30‹ C. and recovering the product, e.g. after treatment of the reaction product mixture with an alkali metal carbonate. The 5<SP>1</SP>-phosphate may be obtained in this way or by treating 9-#-D- arabinofuranosyl-hypoxanthine with POCl 3  in trimethyl phosphate at about -5‹ C and pouring the product into ice water containing NaHCO 3 . The 5<SP>1</SP>-O-methyl phosphate is prepared by treating the corresponding adenine nucleotide with sodium nitrite and acetic acid in water as above. The 5<SP>1</SP>-phosphate derivative in which Z is OH and R 1  and R 2  are each OH is obtained by treating 9-#-D-arabinofuranosyl-N<SP>1</SP>- oxide 5<SP>1</SP>-phosphate suspended in water and glacial acetic acid with sodium nitrite under icecool conditions and is converted to the N<SP>1</SP>- benzyloxy derivative by treatment first with 1,5-diazabicyclo[5,4,0]undec-5-ene in dry dimethyl sulphoxide and then with benzyl bromide. Examples are also given for the production of the N<SP>1</SP>-methyl-5<SP>1</SP>-phosphate, N<SP>1</SP>- methyl - 5<SP>1</SP> - O - methylphosphate, the 3<SP>1</SP>,5<SP>1</SP>- cyclic phosphate and the 3<SP>1</SP>-phosphate derivative. Detailed examples are also given for the production of 9-#-D-arabinofuranosyladenine- 51 - O - methyl phosphate, 9 - # - D - arabinofuranosyladenine - N<SP>1</SP> - oxide - 51 - phosphate and 9 - # - D - arabinofuranosyladenine - 31- phosphate which are used as intermediates. The products I when obtained in free acid form may be reacted with a base to form the corresponding salts, e.g. the Na, Ca, Ba, K, ammonium or substituted ammonium salts, thus the disodium salt can be prepared by reaction with NaHCO 3 . The products have antiviral activity and may be used in admixture with a pharmaceutically acceptable carrier.

Title: Improvements in or relating to bituminous emulsions
IPC: C08L95/00
Filed: 1924-05-31
Abstract: 243,398. Hay, G. S. May 31, 1924. Emulsions, making.-Bituminous emulsions are prepared by mixing with liquid or molten bituminous materials a proportion (up to about 10 per cent) of an emulsifying agent comprising starch or other farinaceous substance or dextrin and an aqueous solution of alkali. The starch or dextrin may be replaced in part by fatty acid, and starch may be used in the form of an alkali gel. According to one example asphalt is melted at a temperature of 215-235‹ F., starch or dextrin is incorporated, and a dilute solution of caustic potash then added. Boiling water is finally poured in to bring the emulsion to the required consistency, and the mixture is agitated until emulsification is complete. The process mav be modified by (1) using in place of caustic potash other alkalis such as caustic soda or sodium or potassium carbonate or silicate, (2) mixing the ingredients in a cold state, and (3) varying the order or manner of mixing, as by adding the alkali before the emulsifier or by adding the bitumen to the emulsifier or to a mixture of the emulsifier and alkali. The emulsions are intended for use as a binding medium in roadmaking or in the manufacture of fuel briquettes, for impregnating concrete, or for preserving building or fencing materials such as stone or wood or roofing materials such as felt. Specification 230,177 is referred to.

Abstract: 845,093. Moulding foamed polystyrene. DEUTSCHE FRIGOLIT G.m.b.H. April 24, 1959, No. 14138/59. Class 87(2). [Also in Group XXV] Large blocks of foamed polystyrene are made by filling pre-foamed small particles into the separate chambers of a common mould, the chambers being separated by perforated parallel partitions 7 which extend vertically of the mould and are slightly movable in a direction normal to their main surfaces, closing the mould, subjecting the resin to a short heating by injecting steam, then interrupting the steam supply and slowly cooling the formed blocks before removing them. The partitions 7 are connected by means of edge holes 7a, Fig. 1a, to inwardly projecting pins 7b of the adjoining walls 2, 5 of the mould, the pins having play in the edge holes thus permitting equalisation of the expansion pressure of the pre-foamed material which arises when the softening temperature is attained. Steam is introduced through the perforated walls 2, 3, 6 of the mould from pipes 8 and since the partitions 7 are also perforated, the initially crumbly mass is rapidly traversed by the steam and any condensate is driven out of the mould through the perforations of the remaining walls. To facilitate removal of the moulded bodies after cooling, the cover 4 is hinged and two adjacent side walls 5, 6 are hinged to the two other side walls 2, 3. These hinged side walls are held together by releasable locking means, other releasable locking means being used to secure the hinged side walls to the bottom 1 and the cover 4 to the side walls.
