Title: Improvements in counting scales
IPC: G01G19/42
Filed: 1921-07-08
Abstract: 173,472. Toledo Scale Co., (Assignees of Thomas, E. G.). Dec. 29, 1920, [Convention date]. Computing-apparatus.-Relates to a machine for counting large numhers of small articles by weighing. The machine shown is of the pendulum tpye although the invention is of general application. The machine has the usual fanshaped scale 10, which is graduated as shown in Fig. 3. The bottom row of figures indicates weight in pounds and ounces, while the rows from the heavy line a downwards are marked 50, 100, &c. as shown. Each graduation in the row marked 50 represents the position to which 50 articles of a given average weight will bring the indicator 11. The other rows are similarly graduated, and numbered with index figures to be assigned to various types of articles. These index figures may be determined for articles, by counting out say 50 articles and weighing, when the indicator 11 will give the required figure on line 50. To save counting out as many as 50 articles the scale is provided with a specimen pan 14 suspended from a knife-edge 17 at the end of the lever 13, which increases the leverage to ten times. Thus 5 objects in the pan 14 will give the game reading as 50 in the scoop 8. Index figures of articles placed in the pan 14 are indicated on the scales above the heavy line a. To facilitate reading, the pointer 11 is graduated as shown to correspond with the various scales. A poise 18 may be fitted to the lever 13 for counterbalancing the weight of containers, or for direct weighing. In place of the ratio pan, an auxiliary snale may be employed.

Title: Esters of pentaerythritol acetals and ketols
IPC: C07D319/06
Filed: 1943-11-19
Abstract: Cyclic ethers of pentaerythritol having the formula <FORM:0579179/IV/1> wherein R1 and R2 are hydrogen or alkyl groups are esterified with carboxylic acids to give the diesters.  The cyclic ethers are prepared by treating pentaerythritol with an aliphatic aldehyde or ketone so that two of the hydroxy groups form an acetal or ketal linkage.  Preferably, the cyclic ethers are made under the action of an acid catalyst and the ester under the action of a basic catalyst such as an alkali salt of the acid. When the acid employed contains up to 4 carbon atoms and the acetal is derived from a saturated aldehyde containing up to 5 carbon atoms or the alkyl groups of the ketal contain up to 4 carbon atoms, the product is a plasticiser for cellulose esters and ethers; the higher products such as those in which the alkyl groups of the acids and/or those of the ketal or acetal groupings contain 7 or 8 or more carbon atoms are ingredients for lubricants for cellulose acetate yarns.  In examples: (1) pentaerythritol is condensed with formaldehyde in presence of sulphuric acid and the formal is esterified with acetic anhydride and sodium acetate; (3) pentaerythritol is condensed with butyraldehyde and the butyral esterified with acetic anhydride; (5) pentaerythritol is condensed with acetaldehyde and the acetal is esterified with acetic anhydride.  Samples have been furnished under Sect. 2 (5) of a dibenzoyl ester of the cyclic ether and of cellulose acetate film plasticised therewith.

Title: Fluid flow control valve
IPC: E03D3/06
Filed: 1974-05-06
Abstract: 1464398 Valves E P SCRAGG 6 May 1974 [11 May 1973 4 June 1973] 19828/74 Heading F2V In a flushing valve, operation of a lever 66 lifts a pilot valve 46 off its seat to allow water to flow from a chamber 34 bounded by a flexible diaphragm 114. Pressure within the chamber falls and the diaphragm flexes upwards under the influence of water pressure below the diaphragm. This upward movement causes a surface 48 on a stem 42 attached to the diaphragm to lift from a seat 80 to allow water from an inlet 96 to flow to an outlet 56. On release of the lever 66 pilot valve 46 closes and water flows into the chamber 34 via a restricted passageway 32 and the surface 48 re-seats to stop the flow of water. The diaphragm 114 is provided with a frusto-conical strengthening plate 118 which inhibits inward collapse of the peripheral part of a rubber moulding 110, a part of which forms the diaphragm 114, while allowing the diaphragm to reverse its conicity. The plate 118 has the additional function of retarding the movement of the diaphragm 114 by trapping water between the two parts. A needle 82 attached to the pilot valve 46 cleans the passageway 32 every time the valve is operated. A cone 94 deflects dust away from the passageway: its position can be varied to vary the closing time of the valve. An adjustable stop 106 limits the travel of the lever 66. The valve may be used alternatively as a shower valve, a rose 90 being fitted to the outlet and an actuating knob 92 being provided instead of the lever 66. In a modified form of the valve, Fig. 2 (not shown), provision is made for direct lifting of the stem 42 so that operation of the valve is not dependent upon water pressure to lift the diaphragm. The valve 46 is first opened as in the above described embodiment and the actuating mechanism has a lost-motion connection with the lower end of the stem 42.
