Title: Process far preparing diesters of cis-propenyl-phosphonic acid
IPC: C07F9/141
Filed: 1969-05-12
Abstract: Diester derivatives of cis - propenyl phosphonic acid are obtained by treating a diester of ethynyl phosphonic acid with tetramethyl diborane, generally in an inert solvent, to yield a trans diester of 2 - (dimethyl boryl) vinyl phosphonic acid and treating the latter with iodine in the presence of a base e.g. an alkali metal- or alkaline earth metal hydroxide, preferably in an inert solvent. The reaction is generally conducted at below 40 C., preferably - 10 to 0 C. The diester product may be hydrolysed to the free cis - propenyl phosphonic acid e.g. by treatment with a mineral acid in the presence of a buffer, or by treatment with trimethylchlorosilane or toluene sulphonic acid and the phosphonic acid may then be epoxidized to ( )(cis - 1,2 - epoxypropyl)phosphonic acid, e.g. by treatment with H 2 O 2 in the presence of an alkali metal pertungstate. The racemic mixture of ( )(cis - 1,2 - epoxypropyl)phosphonic acid thus obtained can be resolved into its optically active components by the crystallization of salts of the acid prepared by reacting the acid with an optically active base, e.g. quinine, d - [alpha] - phenethylamine, strychnine or quinidine and the resulting salts, after isolation, can be treated with a base, e.g. NaOH, NH 4 OH or CaC0 3 to form the corresponding salt e.g. of (-)(cis - 1,2 - epoxypropyl)phosphonic acid from which the free acid may be obtained e.g. by passage through an ion exchange resin at 0-5 C. on the hydrogen cycle. The ( ) and (-) (cis - 1,2- epoxypropyl)phosphonic acid and salts thereof have antimicrobial properties. The ester derivatives of ethynylphosphonic acid may be prepared by treating 3-pyranyloxy- 3 - methyl - 1 - bromo - 1 - butyne with a diester derivative of sodium phosphite to yield the diester derivative of 3 - hydroxy - 3 - methyl - 1 - butynyl phosphonate and then treating the latter with caesium carbonate at elevated temperature and under reduced pressure. The sodium diester phosphite may be prepared by treating a phosphite diester with sodium hydride.

Title: Float glass apparatus with means for inserting wire
IPC: C03B18/12
Filed: 1969-06-14
Abstract: In the manufacture of float glass, a wire inlay is introduced downwards into the glass strip when it is at a temperature of about 1050 C. by means of a wire inlay guiding means which is maintained clear of the glass surface and the surface of the glass downstream from the point of introduction is heated to ensure an even plane surface. As shown in Fig. 1, molten glass 1 is cast on to a bath 4 of molten tin 3 and in the first and hottest zone 3A spreads out to a glass strip 11 of width determined by side limiting bodies 5 of graphite which have a central hole (6) for the supply of cooling fluid which, if porous graphite is used, may be a protective gas or liquid tin to assist movement of the glass strip 11. In the midlde zone 3B, the tin is cooled by side cooling tubes (13) and bottom tubes 12 to maintain the glass at about 1050 C., the zone 3B being deeper than adjacent zones and with barriers 14 to ensure an even cooling. Above this zone, and set into roof 28 of the bath 4, is the wire inlay supply and guiding means comprising supply rolls 24, feed rolls 22, 23 and guide bodies 20, 21 all except the tips of the bodies 20, 21 being enclosed in a gas tight housing 26. After the wire inlay 10 is introduced into the strip 11, the strip passes to zone 3C where heaters 31 re-form the top surface of the glass which may otherwise show cuts from the wire inlay. As shown in Fig. 4, in zone 3B, the bodies 5 and deeper bath are replaced by a graphite barrier 41 with cooling tubes 40, the barrier 41 having projections 42 for limiting the width of the glass strip 11. The guide bodies 20, 21 are curved as shown and are provided with heat-insulated outer and bottom surfaces and are hollow with coolant flowed therethrough. To supply separate wires, the guides 20, 21 are replaced by double-walled guide tubes. The guides 20, 21 may be adjustably mounted to vary the height relative to the glass and also the inclination. As shown in Fig. 7, the body 20 may be replaced by a pair of guides 70, 71 with a space between through which hot protective gas via duct 75 is blown on to the glass strip 11 and which depresses the strip 11 and tin 3 below it to form a curve 74 so that the wire inlay 76 can be led into the strip 11 at the level required. In a further embodiment (Fig. 8, not shown), the wire inlay 76, led over guide body 21, enters the glass strip which is raised over a barrier (80), the top part (82) of which is of porous graphite and molten tin is pumped with a central hole (81) so as to pass through the barrier to give a layer (83) of tin below the raised glass layer (84). Reference has been directed by the Comptroller to Specification 1,157,406.

Title: Ionization-type fire or smoke sensing system
IPC: G08B17/10
Filed: 1976-07-12
Abstract: To render an ionization-type sensing element essentially immune to changes in ambient conditions, principally temperature or operating voltage, while still using low-current draining circuits to sense response of the ionization chamber of the sensor, the threshold response level of a field effect transistor (FET) is arranged to have approximately the same temperature response characteristic, within the range of ambient temperature considered, as the ionization cell so that the overall circuit or system combination of the cell and FET amplifier will have a response which is essentially independent of ambient temperature or similar conditions. The source path of the FET is connected to a voltage divider which is so dimensioned that the voltage division ratio (R2/R1) is related to the temperature coefficient ( alpha ) of the base-emitter voltage of the FET and the temperature coefficient ( beta ) of the measuring ionization cell chamber:

Patent ES-8100473-A1 (ES)
Title: Electromagnetic Temperature Control Arrangement for Refrigerators
IPC: F25D21/00
Filed: 1980-03-20
Abstract: In refrigerators having two compartments 2,3 (Fig. 1) for respectively preserving fresh and frozen foods, the frozen food compartment normally held at about -18 DEG C cannot be used to freeze foods because regulations require a considerably lower temperature (e.g. -30 DEG C) that will freeze foods within 24 hours. The temperature control arrangement includes a two-way switch 26 (Fig. 3) which can be set by the user to cause the frozen food compartment to reach such a low temperature that foods can be frozen within a prescribed or determined period. A temperature sensor 14 e.g. an NTC Thermistor is located in the coldest part of the fresh food compartment and is connected in an arm of a bridge circuit means for comparing the compartment temperature with a first or a second reference temperature value set up on pot 25 and R50 and selectable by switch 16. Means e.g. a triac 33 Fig. 3 controls the operation of the refrigeration circuit compressor 6 in dependence upon the result of the comparison. Selection of the first reference temperature signal causes the temperature in compartment 2 to be held at, for example 4 DEG C and hence the temperature in compartment 3 to be held at, for example, -18 DEG C. Selection of the second reference temperature signal causes the temperatures in the compartments 2 and 3 to be held at, for example, 1.5 DEG C and -30 DEG C respectively. A thermistor 15 responsive to evaporator temperature, is connected in a second bridge circuit coupled to amplifier C. This functions to activate the compressor 6 when a given temperature is detected indicating that defrosting by a heater M is completed. The defroster heater may be timer controlled.
