Title: Improvements in carriage-stop mechanism for typewriting machines
IPC: B41J21/06
Filed: 1930-02-28
Abstract: 341,326. Typewriters. ELECTROMATIC TYPEWRITERS. Inc., 60, Commercial Street, Rochester, New York, U.S.A.-(Assignees of Crumrine, C. W.; 60, Commercial Street, Rochester, New York, U.S.A.) Feb. 28, 1930, No. 6674. Convention date, July 25, 1929. [Class 100 (iv).] Margin stops ; tabulating-mechanism.-A yielding stop-member can be rocked to co-operate alternatively with margin stops or tabulating-stops on the carriage. The tabulating-stops may co-operate with a rebound-preventing catch provided with a detent which is set and released by the stop-member. In the mechanism shown in Figs. 1, 4, and 5, a stoplever 27 having lugs 39, 40 for engaging margin stops 18,19 and tabulating-stops 20 on the carriage 14 is carried by a lever 29 freely mounted on a pivot 30. The stop-lever has a slot 41 engaging a lever 42 which is connected by a link 47 to a tabulating-key, and is carried by a bell crank 44 abutting on a rod 48 operated by a margin-release key. The lever 29 is held in normal position by a spring 34 and, after the stop-lever has moved longitudinally, yieldingly arrests the carriage by engagement with one or other of two stop-pads 37. The pivot 30 is carried by an arm 31 which is secured at one end 32 to the framework and is formed with a bend 31<a> which yields when the carriage is arrested. The lug 39 is normally in the path of the margin stops, the margin-release key being depressed to rock the stop-lever for margin release. For tabulating, the lug 40 is moved into the path of the tabulating-stops by depressing the tabulating-key and thereby causing the lever 29 to rock on a vertical axis in opposition to a spring 33. The stop-lever is held in tabulating position by means of a spring-urged pivoted dog 58 and a co-operating finger 64 on the stop-lever. The dog is normally restrained by the finger but when the stop-lever is moved into tabulating position the dog is swung and obstructs the finger. When the stop-lever is moved longitudinally, the finger clears the dog and on return of the stop-lever the dog is returned to normal position. A reboundpreventing catch 66 pivoted on a pin 65 co-operates with a detent 59 on the dog 58. The catch is moved aside by the tabulating-stop and is then locked by the detent, so that on return of the stop-lever the tabulating-stop is obstructed by the catch, and thereafter the dog 58 is returned and the detent is released from the catch. Carriage-releasing arrangements.-The stop-lever 27, when moved into tabulating position, rocks a lever 50 and a finger 55 thereon moves escapement dogs 22 out of engagement with the feed-rack 21.

Title: Improvements in or relating to a method and apparatus for Seismic Detection
Inventor: WHITE JAMES EDWARD
IPC: G01V1/46
Filed: 1968-02-12
Abstract: 1,193,382. Seismic prospecting. MARATHON OIL CO. 12 Feb., 1968 [11 Feb., 1967], No. 6872/68. Heading H4D. In a system for detecting inhomogeneities in the earth by reflection of acoustic energy, an energy field having a predetermined spatial pattern is radiated from within a borehole and echo signals are sensed by a detector in the borehole and insensitive to energy with that pattern, whereby the detector discriminates against directly-received energy and responds to echoes and other waves not having the predetermined pattern. The field is generated by energizing four barium titanate cylinder segments 47, or a transducer assembly similar to that disclosed in Specification 1,193,381 (see Division H4), with signals of selected amplitude and phase for propagating shear or compressional waves (either as pulses or with varying frequency) in the earth. Similar transducers 46 receive echoes of these waves and their electrical outputs are combined such that received waves with the same spatial pattern as the transmitted waves give no nett output. Thus if the earth formations are symmetrical about the borehole zero nett output is obtained, but inhomogeneities (i.e. asymmetry) modify the field pattern and result in a nett output. The receiving transducer outputs may be recorded individually for later addition by computer. In a modification, acoustic shear wave energy is generated by the impact of a moving mass against a stationary mass contacting the borehole wall, the impact being tangential to the borehole wall.
