Title: Windshield wiper arm and blade connectors
IPC: B60S1/52
Filed: 1947-07-21
Abstract: 644,048. Automatic catches. PRODUCTIVE INVENTIONS, Inc. July 21, 1947, No. 19502. Convention date, June 25, 1943. [Class 44] [Also in Group XXIII] A connector for hingedly connecting a windshield wiper arm and blade (see Group XXIII) includes an attachment member on the blade having trunnions, a member on the arm having slots therein to receive the trunnions and movable transversely thereof between locking and unlocking positions, means cooperating with the slots when the movable member is locked and spring actuated means to retain the movable member locked. The movable member 29, Fig. 4, comprises a base 30a and two side walls 30b, each having a slot 34 slidable and pivotal on a pin 35 fixed between the side walls 19b of a channel sectioned wiper arm 19. The base 30a is formed with two neck portions 37, Fig. 5, which are upwardly bent to provide finger pieces 36, Fig. 2, which lie adjacent the exterior of the side walls 19b of the arm. The member 29 is biassed to locking position by a tension spring 31. Each side wall 30b of the member 29 is provided with a slot 40 defined by an upper jaw 32a and a shorter lower jaw 32b. When the member 29 is in the unlocked position indicated in Fig. 4 the upper jaws 32a are adjacent the rounded ends of slots 33 formed in the side walls 19b of the arm. The member 29 is retained in the unlocked position against the action of the spring 31 by necks 37 abutting detaining notches 38 formed in the lower edges of the side walls 19b. Trunnions 46, Figs. 2 and 7, fitted to an attachment means 15 connected to a wiper blade frame 14 are inserted in the slots 33 to engage with the upper jaws 32a. When sufficient pressure is exerted the member 29 will pivot in a clockwise direction about the pin 35 to release the necks 37 from the detaining notches 38. The spring 31 will then cause the member 29 to move forward and pivot in a clockwise direction due to the arrangement of the slots 34 in the side walls 30b. The member 29 then assumes the locked position indicated in Figs. 2, 3 and 5, and any tendency for it to move in an anti-clockwise direction is prevented by the necks 37 engaging portions 37a of the bottoms of the side walls 19b. The adjacent cooperating slots 33, 40 imprison the trunnions and form bearings about which the blade frame 14 can pivot so as to ensure uniform contact of the blade 13, Fig. 2, with the windshield. The blade can pivot to a limited extent relative to the trunnion sleeve 45, Fig. 7. In a modification, Fig. 17, a locking member 79 is detained in the unlocked position bythe nose 89 of a member 88 pivoted on a pin 92 fixed between the side walls 19b of the wiper arm, and controlled by a spring 93. Specification 655,260 is referred to.

Title: Aromatic acyl chlorides
Inventor: KATZSCHMANN EWALD
IPC: C07C51/62
Filed: 1960-06-02
Abstract: The chlorides of aromatic carboxylic acids, substituted in the nucleus by chlorine, are made by treating with chlorine an ester of an aromatic mono- or poly-carboxylic acid while it is exposed to light whereby the corresponding acid chloride is obtained, then introducing a catalyst, such as iron filings or ferric chloride, and continuing the chlorination to produce the desired nuclear chloro-substituted compound.  In Example 1, dichloroterephthaloyl dichloride is obtained by chlorinating dimethylterephthalate, the first stage of chlorine-treatment being carried out at 160 DEG C.-195 DEG C., and the second at 220 DEG C.  When hydrolysed, the product yields dichloroterephthalic acid.  Example 3 also describes the chlorination of dimethyl terephthalate, but in this example, the product is tetrachloroterephthaloyl dichloride.  In Example 4, dimethyl terephthalate is chlorinated, and the product is refluxed with methanol whereby the dimethyl ester of tetrachloro-terephthalic acid is obtained.  Example 2 describes the production of pentachlorobenzoyl chloride by chlorination of methyl benzoate.

Title: Improvements relating to motor control systems
Inventor: ASBURY ALLAN
IPC: H02P5/50
Filed: 1948-07-22
Abstract: 645,774. Automatic speed control systems. ENGLISH ELECTRIC CO., Ltd. July 22, 1948, No. 19606. [Class 38 (iv)] [Also in Group XXXVII] In an automatic speed control system for a number of D.C. motors, in which there is a master controller for all motors, and individual automatic controls for each motor, the reference voltage for automatically controlling each motor is derived from a potentiometer connected in cascade to the slide of the reference potentiometer of the previous motor in turn connected to a source, the voltage of which is dependent on the position of the master controller. The five motors 10, 20, 30, 40, 50 have their armatures supplied from a main generator 11 so that all their speeds may be controlled simultaneously by a master field regulator 13. The speeds of individual motors may be set by individual field regulators, e.g. 14. The speed of each motor is maintained constant by an auxiliary field supplied from an electronic amplifier, e.g. 15, according to the resultant of a voltage from a tachometer generator, e.g. 16, and a reference voltage tapped off a potentiometer, e.g. 17. The reference voltage for motor 20 is tapped from the main supply off a master reference potentiometer 28 ganged to the master controller 13. The reference voltage for motor 10 is tapped in cascade off potentiometer 27. Similarly the reference voltage for motor 30 is tapped off the potentiometer 28 and the voltages for motors 40 and 50 tapped in cascade off successive reference voltage potentiometers. The master reference potentiometer 28 may be replaced by an exciter coupled to the main generator. In an alternative arrangement, the section motors are each supplied from separate generators, and the mastercontroller varies the excitation of all the generators simultaneously. The control field windings supplied from the electronic amplifiers may in this case be either on the generators or on the motors. Reference has been directed by the Comptroller to Specification 627,922.
