Patent GB-815991-A (GB)
Title: Dibenzoate esters of aliphatic diols and process for their preparation
Filed: 1956-02-27
Abstract: The invention comprises a process for preparing dibenzoate esters of aliphatic diols wherein butyl benzoate is reacted with an aliphatic diol having 4 to 9 carbon atoms and no "tertiary hydroxyl groups," and also the dibenzoate esters of 2 - ethyl - 1 : 3 - hexanediol, 2 - methyl- or -ethyl - 1 : 5 - pentanediol, 2 - ethyl - 3 - methyl-or 2 : 4-diethyl-1 : 5-pentanediol and 2-ethyl-2-butyl- or 2-methyl-2-propyl-1 : 3-propanediol.  A "tertiary hydroxyl group" is one which is attached to a tertiary carbon atom.  Preferably, 1 mol. of the aliphatic diol is reacted with 2.5 mols. of butyl benzoate in the presence of an alkaline catalyst at a temperature of 100 DEG  to 250 DEG  C. and at a pressure from 0.1 mm. to 200 mm. Hg.  Suitable catalysts are the alkali and alkaline earth metal oxides, hydroxides, alkoxides, carbonates and borates.  Diols specified in addition to those in examples are 1 : 5-pentanediol and 2 : 5-hexanediol.  In an example, butyl benzoate, dipropylene glycol and calcium oxide are mixed in a reaction vessel fitted with a stirrer and fractionating column, distilled in vacuo to give a first fraction of butanol, a mid-fraction of butanol and butyl benzoate and a final fraction of butyl benzoate, the residue is filtered to remove catalyst, stripped, treated with a decolorizing agent and filtered to give dipropylene glycol dibenzoate.  Alternatively, the ester may be obtained as a fourth fraction in the vacuum distillation.  The dibenzoate esters of the following diols are prepared similarly: diethylene glycol, 2-ethyl-1 : 3-hexanediol, 2 - methoxymethyl - 2 : 4 - dimethyl - 1 : 5 - pentanediol, 2 : 4 - diethyl- or 2 - methyl - 3 - methyl - 1 : 5 - pentanediol, 2- or 3-methyl- or 2-ethyl-1 : 5-pentanediol and 2 - ethyl - 2 - butyl- or 2 : 2 - diethyl- or 2-methyl-2-propyl-1 : 3-propanediol.

Title: Improvements in the manufacture of organic substitution derivatives of cellulose
IPC: C08B9/00
Filed: 1929-11-28
Abstract: Halogen containing cellulose derivatives are produced by treating a carboxy or hydroxy ester or ether of cellulose by the methods known for the halogenation of simple hydroxy groups or hydroxy radicles in carboxy groups.  For example, the cellulose ester or ether, such as cellulose glycollate, hydroxy ethyl cellulose, or cellulose glycollic acid may be treated with thionyl chloride directly, or in presence of a solvent or non-solvent diluent.  By working in the presence of a non-solvent, halogenated derivatives having a fibrous structure may be obtained.  For examples, (1) cellulose glycollic acid is dissolved or suspended in benzene and treated with thionyl chloride; the excess of thionyl chloride and benzene are removed under vacuum and the cellulose derivative washed with ligroin.  (2) Oxyethyl cellulose is treated as in (1) above.  (3) Cellulose malonate, phthalate, malate, or maleate is treated with thionyl chloride as described in (1). Specifications 166,767, 277,721, 316,160, 320,842, [all in Class 2 (ii), Cellulose, &c.], 343,521, and 344,480 are referred to.

Abstract: 919,747. Sensing record cards. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. Feb. 20, 1961 [Feb. 29, 1960], No. 6138/61. Class 106 (1). Punched record cards are sensed by being moved past a column of photo-cells 53, Fig. 1, pairs of photo-cells 41, 42 and 45, 46 being provided to detect the leading and trailing edges of the card to operate a " card present " trigger 48 timing pulses from a disc 34 rotating with the card feed being passed by gate 51 to a counter 52 during the time a card is present at the sensing position. The disc 34 has teeth or transparent areas 35 which are sensed photoelectrically to produce ten pulses during the time the card moves one column pitch. The counter 52 consists of a chain of four transistor triggers interconnected to count up to ten. A control pulse is provided by the counter for each column of the record and serves to enter the data sensed into some utilization device shown as a storage matrix 55. The signal from the photo-cells 41, 42 controls a circuit 49 to reset both the counter and the storage matrix at the start of the sensing operation. The photocells 41, 42 and 45, 46 are photo-diodes and are connected in pairs in series, as shown in Fig. 9. The associated transistor amplifier responds to the masking of either cell to produce a setting output for the trigger 48. This allows the card to be fed with the cut-away corner 57 in any of four positions because the circuits will be operated by the photo-diode 42 corresponding to the other corner. Instead of column-bycolumn, sensing may be row-by-row.

Abstract: 176,789. Beck, F. C. March 11, 1921, [Convention date]. Pumps, syringes, and like appliances.-In a vaginal irrigator of the type comprising a closed liquid reservoir, a pumping device, and a vaginal obturator traversed by inflow and outflow passages, the outflow passage is connected to the reservoir so that a closed circulatory system is set up and outflow of the injected liquid from the vagina is accelerated. In an elementary form shown in Fig. 1 a closed reservoir 1 is connected to a pipe 3a and enema syringe 2 having valves 2<a>, 2b and to a returnflow pipe 5. The syringe 2 and pipe 5 are both in communication with a nozzle pipe 3<c> which traverses the obturator 4. The valve 2<b> normallv closes the syringe 2 but when open is so arranged as to close the outflow pipe 5. In the form shown in Fig. 2 the closed, reservoir comprises a liquid container 1<a> and a receiving vessel 1<b> separated by a partition 1<c> and held together by clamps. A pipe 1<d> connects the receiver 1<b> with the upper part of the reservoir 1<a>. A suction pipe 7 connected to the syringe 2 and an overflow pipe 8 connected to the return pipe 5 are arranged in the positions shown. An air inlet valve controlled from outside the apparatus may be arranged at the top of the pipe 7 so that, after irrigation, air may be pumped to the vagina to expel any remaining liquid. Fig. 3 shows a modification in which an inverted vacuum flask 1 or any other bottle serves as the closed reservoir and is connected to the pump 2 by a liquid supply tube 3a and by an air pipe 14 either of which may be put into communication with the pump by manipulation of a valve comprising a tubular plunger 3<b> operated by a rotary member 11. A return flow tube 5 passing through the tube 3<a> to the top of the inverted flask is also provided. In this form the connection between the reservoir 1 and the vaginal obturator 4 is rigid and the valve 3b is arranged in a position above the obturator 4. In further modifications the pump 2 may be arranged in the return flow pipe instead of the inflow pipe or may be replaced by any other liquid forcing means. In a modification of the form shown in Fig. 3 the transition from water pumping to air pumping may be effected by a device for connecting the orifice of the inflow pipe with the outflow pipe and vice versa.
